Polypropylene pipes: description, types, photo installation, properties, marking

Polypropylene pipes are a popular material used for arranging water supply systems and heating various premises. Their popularity is explained by their long service life, resistance to low and high temperatures, corrosion, and reasonable price. The main thing is to choose a quality product. For this reason, you need to know which polypropylene pipes for heating are best to choose. We have compiled for you the TOP 10 types and manufacturers of this building material.

What properties do different types of polypropylene pipes have?

Polypropylene is a thermoplastic synthetic non-polar polymer. The polymerization method using a Ziegler-Natta catalyst was invented in 1957, and since then the production of products with an isotactic structure characterized by high strength

, heat resistance and a high degree of crystallinity.

Polypropylene is a material that is resistant to acid, alkaline and saline solutions, as well as other inorganic substances. It does not absorb liquid and retains its electrical insulating properties over a wide range of temperatures.

Based on polypropylene, various modified materials are produced, such as thermoplastic, high-strength plastic and other environmentally friendly products. Recycling and recycling are a technological process, due to which polypropylene is actively displacing products made from other types of plastics from the world market.

Polypropylene melts at a temperature of +164…+170 °C

, Brinell hardness ranges from 40 to 70 MPa, brittleness temperature - from
-10 to -15 ° C
, tensile failure stress (kgf/cm2) - from 250 to 400, flexural modulus of elasticity (kgf) - from 6700 to 11900 .

A huge number of products that are popular on the market today are made on the basis of sheet propylene. To produce this material, the extrusion method is used. Depending on the shade, smoothness and other factors, sheets are divided into two classes. They are used for the production of pipeline systems, connecting them together in different ways, one of which is welding.

Types of polypropylene pipes

Polypropylene (accepted international designation - PP) has been used for quite a long time for the manufacture of pipes as a base material. However, only the development of modern technologies has made it possible to obtain products that can be used for hot water supply and heating systems.

Polypropylene itself is characterized by its pronounced inertness to the chemical effects of a possible liquid coolant medium. However, in terms of heat resistance and strength, different types can differ significantly from each other.

So, pipes made of this material are divided into three main types, which have their own designations:

PP-N are intended for cold water only

• PP-N is the first type of polypropylene pipes, inert to chemical influences, but not resistant to elevated temperatures. Therefore, they are intended for cold water supply, sewerage, drainage systems, ventilation and other applications where elevated temperatures are not expected. Very often, this type of pipe is prevalent for industrial production lines, as it is highly resistant to increased internal pressure.

The range of possible applications of PP-V pipes is somewhat wider, but for heating they are still “weak”

• PP-B is the second type of polypropylene pipes, which has all the same advantages of PP-N, but, in addition, has the ability to withstand temperature loads of low amplitude. Therefore, they can be installed on separate main sections of “warm floor” systems. And also in hot water supply circuits, provided that the water or coolant does not heat above 50 degrees.

However, the main scope of application of PP-B is different. Most often, such pipes are used for sewer systems, since the material from which they are made has a sufficient degree of impact strength and heat resistance for this area.

Only PPR pipes are fully suitable for heating systems

• PPRC, PPR or PP-3 is the most advanced type of pipes that is used in hot water supply and heating systems, that is, where temperatures can exceed 50 degrees and there is a possibility of increased compression loads. Increased heat resistance and mechanical strength are achieved thanks to special production technologies, in which ethylene molecules are introduced into the molecular lattice of propylene during synthesis.

PPR are pipes that are most widely used in domestic conditions, as they have a pronounced resistance to internal pressure and temperature changes.

Polypropylene pipes (PPR), used in domestic conditions, in turn, are divided into several types, depending on resistance to baric loads: PN -25; PN -20; PN -16; PN -10. Their main characteristics are given in the table:

Each type of pipe is produced in a fairly wide range of diameters, internal and external: on which the wall thickness depends

Naturally, the values ​​of diameters and wall thicknesses directly affect the resistance of pipes to temperature and pressure, which, in principle, determines the duration of their possible operation in certain conditions:

The data presented in the tables is the result of long-term testing of pipes under various conditions, which even theoretically may arise during their operation, so it is worth taking them into account in the process of selecting the required material.

Polypropylene pipes can have different colors, but when choosing them you should not pay special attention to it (perhaps only from an aesthetic point of view) since the external color does not in any way determine the characteristics of the products and does not affect their quality.

A red or blue stripe may be applied to the surface of some pipes - it serves as a specific indicator of the purpose of a particular type. Thus, blue color is applied to cold water supply pipes, and red indicates the ability of the products to withstand elevated temperatures in the hot water system or heating circuit.

When purchasing pipes, be sure to pay attention to their markings.

In addition to colored stripes, the pipes are marked with letters, which indicate their characteristics and intended purpose for installation in certain water supply or heating systems, and you also need to pay attention to it. The meaning of the marking indicators corresponds to the information given in the tables.

As can be seen from the presented characteristics, PN-20 products are optimally suited for the heating system, but the ideal option would still be PN-25 pipes, which have pronounced resistance to elevated temperatures and pressure, even with a good margin.

Czech

The Czech Republic is represented on the domestic market by Wavin Ekoplastik and Fv Plast

Wavin Ekoplastik

The Czech company Wavin Ekoplastik uses random, a PP-R copolymer, for cold water supply pipes. And for heat-resistant pipes - high-quality heat-stabilized PP-RCT, similar to those from German manufacturers.

The products of this company are in demand in the domestic market due to high quality fittings and shut-off valves. Additional components allow you to lay a pipeline of any configuration. The price of Wavin Ekoplastik products is not much different from their German counterparts, and their reliability is not inferior to them. The only disadvantage of products from the Czech Republic is the not very attractive gray color of the products, which requires decoration.

Fv Plast

FV-Plast pipes are inferior to Ekoplastik in popularity due to the poorly developed dealer network in our country. The quality is no worse than that of its closest competitor. The pipes of this company are designed for use in cold and hot water supply pipelines, underfloor heating and heating systems.

It is necessary to note the exceptional lightness of FV-Plast pipes, which facilitates the installation of heated floors.

The FV-Plast company has made the production of reinforced polypropylene pipes a priority. The technology involves reinforcement with aluminum foil and fiberglass.

The manufacturer has provided a wide selection of related parts: fittings, shut-off valves and pipe fastening systems.

Conclusion: Having examined both options for Czech pipes, we can state that they do not differ in quality from German ones, and the price is still lower. The only indicator in which they are inferior is the fairly large coefficient of thermal expansion of unreinforced pipes.

Marking of polypropylene pipes

When choosing polypropylene pipes, in addition to the PP type and the presence of reinforcement in the marking, you must also look at the maximum operating pressure. According to GOST, this parameter is designated PN and a number from 10 to 25.

Marking of polypropylene pipes

Depending on this designation, PPR pipes are distinguished as follows:

1. PN10 – thin-walled for cold water and “warm floors” with water up to +450C.
2. PN16 – universal for cold water and hot water supply up to +600C.

1. PN20 – thick-walled for water with temperatures up to +950C.
2. PN25 – with reinforcement for hot water supply and heating (also up to +950C).

For a short period of time, one or another PPR pipe for water supply can withstand exceeding the specified temperatures. But with prolonged excessive heating, it will gradually begin to collapse. And as a result, its service life of half a century declared by manufacturers will be significantly reduced.

Main pipe diameters according to GOST

The diameter in the marking of PPR water pipes is indicated as the outer diameter. Moreover, the larger it is and the higher the PN, the thicker the pipe wall. Products of 16–20 mm are used for installing water pipes throughout the apartment and cottage. 25–32 mm is for the riser. Larger diameter options are intended for pipelines in multi-storey buildings, main networks and sewerage.

How to correctly calculate the diameter of a pipe based on its purpose

How to choose

Everyone's selection criteria are different. Some are interested in the question of what it costs, others study the functionality, others choose the best options, and others check the wall thickness. Everyone is right in their own way. However, experts recommend paying attention to the following indicators:

1. Diameter. Much depends on the scope of application. For internal apartment water supply, a sufficient diameter of 20 - 25 mm. Suitable diameters for risers are from 32 to 40 mm.
2. Maximum permissible pressure. All polypropylene structures, except PN10, are suitable for domestic use. They are produced with thin walls, but withstand significant pressure (10 atm.). They won't serve for long. Trunk pipelines are installed from thicker elements.
3. Thermal expansion coefficient. Depends on the choice of installation method. Thus, PN 20 models are not laid using the open method. It can bend and lose its original characteristics, as well as spoil the appearance of the object. The open method is provided for laying polypropylene structures reinforced with aluminum or fiberglass.
4. The maximum permissible temperature reading. The type of coolant that is to be transported inside the pipeline plays a big role. Products PN 16 are suitable for cold water supply systems, PN 25 - for heating systems, PN 20 - for hot water supply.
5. Strength. The indicator is high, but if the products are strongly compressed or when bent, cracks may occur. This must be taken into account during the installation process.
6. Heat resistance. It is assumed that the ambient temperature is not expected to be too low. The optimal option is +15 degrees Celsius, although it will withstand temperatures of 171 degrees, only for a short time.
7. Density. The indicator is 0.91 kg/cc. Polypropylene is wear-resistant and hard, and will withstand interaction with abrasive particles.
8. Persistence. Not afraid of unfavorable environments. It can become unusable only after prolonged “communication” with a strong acid or high temperatures. Salts and impurities cannot harm the product.

Which company is better to purchase products depends on personal preferences. Advice is inappropriate here. Where can I buy? According to buyers, it is best to visit branded stores. There is more choice, and you can chat with a professional manager who will not only introduce you to new products, but also help you make the right choice. You can order products online in an online store, having previously read user reviews, reviewed the product offered, and made sure of the integrity of the supplier.

Aluminum reinforcement

There are solid and perforated reinforcement with aluminum foil.

Continuous reinforcement with aluminum foil is the most economical option for reinforced pipes.

In this case, a thin layer of aluminum is located between the layers of propylene, due to which the structure of the pipe is significantly strengthened. But these types of products, as well as others, are distinguished by a number of limitations in operation:

• the water temperature should not reach +60 °C, otherwise the pipe may become deformed and burst if overheated;
• all joints should be cleaned before soldering, which will significantly reduce the time spent on installing the system;
• the temperature at which aluminum-reinforced pipes freeze is only -5 °C. Therefore, when using this type of polypropylene pipe in a private house, it is strictly forbidden to turn off the heating;
• Experts do not recommend using these types of products to supply hot water, since due to constant temperature changes, the aluminum layer may collapse over time.

Aluminum perforation means a mesh with small holes. During the extrusion of polypropylene pipes, viscous material enters the perforations, thereby ensuring adhesion between the polymer and metal.

Thanks to aluminum reinforcement, the coefficient of thermal expansion is significantly reduced. However, some difficulties may arise during the installation of engineering systems. When socket welding, the aluminum shell and outer layer of polymer are first removed, and the pipe is cleaned to an amount that corresponds to the depth of its insertion into the fitting.

There are types of polypropylene pipes that do not require removal of the outer layer during installation. They, in turn, also have some disadvantages:

• Only the outer layer of the product, equal to half the wall thickness, is attached to the fitting;
• a nozzle for welding equipment is required;
• After you cut the pipe, it will need to be trimmed.

Glass fiber reinforcement

Types of pipes marked PPR-FB-PPR consist of two layers of polypropylene, between which fiberglass is located, which is why this product is called a “fiberglass” pipe.

A pipe reinforced with glass fiber compares favorably with a product with aluminum reinforcement:

• installation does not require calibration and cleaning;
• material and time costs are reduced due to the fact that the soldering procedure is similar to the connection of solid plastic pipes or other stripped polymer products;
• a pipe reinforced with fiberglass does not delaminate because it has a homogeneous structure;
• Glass fiber increases the rigidity of the pipes.

The disadvantage of a fiberglass pipe is that its thermal expansion is 6% higher than that of products with aluminum reinforcement.

Internal reinforcement with polypropylene

These types of products are essentially metal-plastic pipes, the outer layer of which is made of polypropylene. Such pipes are resistant to high temperatures.

The disadvantages of this type of polypropylene pipes are characterized by:

• multilayer - the presence of adhesive joints of two different materials;
• attaching only the outer layer of the product to the fitting;
• the possibility of contact of reinforcement with the transported medium.

Metal-polymer polypropylene pipes

Modern types of polypropylene pipes are distinguished by a classic five-layer metal-polymer construction, shown in the figure below:

This type of polypropylene pipes is used for water supply and heating systems.

Modern polypropylene products have a multilayer construction, just like metal-plastic products. The only difference is that for a classic metal-plastic pipe, PEX or PE-RT polyethylene is used as a polymer, and not polypropylene.

Below is a small table that will help you understand the technical characteristics of all types of polypropylene pipes and the features of their application:

Properties of polypropylene

Polypropylene is a synthetic polymer product in the form of a white powder; a profile is made from it by melting or pressing. This is the hardest and most resistant type of plastic, not subject to corrosion.

The main physical properties of polypropylene are durability, reliability, wear resistance, and resistance to high temperatures. It is not susceptible to the action of chemicals, salts and alkaline solutions, so these substances in water are not dangerous for this pipeline.

Polypropylene products:

• weigh less than steel;
• do not emit substances harmful to health - suitable for installation in domestic premises;
• the inner surface is smooth, which does not allow scale deposits;
• the level of thermal conductivity is low;
• good sound insulation;
• high electrical insulation;
• heat capacity index 2.0 kJ/(kg.°C);
• permissible temperature level -15 - +120;
• density value – 0.92 kg/cm³.

Polypropylene softens at +140 degrees, and the melting point is +175 - this is the temperature of steam.

This factor makes a polypropylene pipeline suitable for cold or hot water supply (especially reinforced ones) , where the temperature of the coolant is kept at +95, but it cannot be used as a steam pipe.

When heated, polypropylene becomes soft, and after cooling, all its physical properties return to it, and it becomes hard again, so assembling a water main from these products is appropriate, and the process of connecting pipeline elements is quite simple. It is enough to heat its ends and join them; it is also possible to connect them with couplings.

The main disadvantage of polypropylene is its plasticity. When heated, the product softens and can be easily bent. But when such a profile is bent, the internal diameter decreases significantly and the throughput level decreases.

In addition, this material is afraid of light; the product may lose its shine, crack, or fade. To avoid this, various components are added to polypropylene.

It is worth noting that polypropylene does not tolerate frost well; it becomes brittle at temperatures ranging from minus 5 to 15 degrees. This material deficiency can also be eliminated by adding ethylene or ethylpropylene rubber.

The standard pressure indicator for polypropylene products is 30 kg per 1 cm2. But according to manufacturers’ recommendations, it should not exceed 10 kg.

MANUFACTURERS OF POLYPROPYLENE PIPES

Domestic and foreign manufacturers offer a wide selection of high quality polypropylene pipes. Moreover, the products of Russian concerns (Valtec, Pro Aqua) are not inferior to foreign brands.

In our company you can order Valtec products. It is used for external and internal communications and has an optimal combination of price and quality. As the official distributor of this Russian-Italian manufacturer, we have the opportunity to offer you Valtec PP pipes and fittings at a better price than our competitors.

Türkiye

Turkey, one of the first countries producing polypropylene pipes, conquered the Russian construction market. Among Turkish manufacturers, the most recognizable are TEBO, PILSA, VALTEC, KALDE, JAKKO.

TEBO

TEBO technics polypropylene pipes comply with all European standards and have a number of competitive advantages:

• High quality raw materials supplied from Germany and South Korea;
• Wide range of models;
• Long service life;
• No marriage.

A wide range of pipes and related materials provide a full cycle of installation operations for engineering communications for any purpose. The TEBO technics brand produces pipes with diameters from 20 to 160 mm, fittings, manifolds, shut-off valves and components. The service life of products for hot water is 30 years, for cold water - 50.

In addition to conventional PP pipes, the model range has been expanded to include reinforced pipes. Pipes reinforced with aluminum have a minimal coefficient of linear expansion. Fiberglass provides increased lateral stiffness.

PILSA

The most famous brand among professional builders. PILSA Plastik Inc. widely represented in 50 countries around the world. PILSA Plastik Inc is part of the Wavin industrial group, the largest European manufacturer of polypropylene products. Of particular interest to consumers is the versatility of using Pilsa pipes at temperatures from -10°C to + 95°C. The elastic material prevents frozen water from destroying the pipes.

Pilsa brand products have a number of advantages:

• Low thermal conductivity;
• High heat resistance;
• Good throughput;
• Pipes and connections do not require maintenance;
• Attractive appearance.

The range of pipes and additional elements is perhaps the richest of all possible. Excellent quality and low price guarantee the company great demand among customers.

But popularity carries with it danger. In the markets you can find fakes from Chinese handicraft workshops.

VALTEC

VALTEC offers consumers single-layer and multi-layer pipes and fittings made of high-strength polypropylene PPR-100 with diameters from 20 to 110 mm. The pipes are intended for drinking and domestic cold and hot water supply systems, as well as for process pipelines transporting non-aggressive liquids and gases. The company produces multilayer polypropylene pipes VALTEC PP-FIBER, reinforced with glass fiber and PP-ALUX - aluminum foil.

The form of delivery of pipes is 2 and 4 meter sections. A fairly modest set of fittings and shut-off valve elements.

The construction market reacts sluggishly to the products of this brand.

KALDE

KALDE is well known for its quality products. The line is represented by unreinforced, aluminum and fiberglass reinforced pipes with a diameter of 20 to 110 mm.

Advantages of KALDE reinforced pipes:

• Reduction of linear expansion by 75%;
• Increased throughput by 20%;
• High impact strength at low temperatures;
• High stability.

All pipeline elements are made of white and gray polypropylene.

The range of fittings includes polypropylene, combined with metal, threaded brass, compression and press fittings. In addition to pipe products, there is no shortage of manifolds, wall kits, ball valves and valves on the market. The manufacturer offers coarse filters, equipment for installation and welding.

JAKKO

Jakko was founded in 2002 in Kazakhstan as a joint venture with Turkey. The company quickly established a wide dealer network in the CIS and ensured the supply of high-quality products. In 2006, it switched to its own production in Turkey.

This brand produces a standard set of polypropylene products in the diameter range from 20 to 125 mm. The brand is little known, the products are little studied, and the reviews are contradictory. For this reason, it is very difficult to recommend Jakko products. Practitioners refer to the identity of Jakko products in terms of quality and range of related materials with VALTEC. And here the price of products in a particular region can play a decisive role.

Characteristics of PPR pipes and scope

Each PPR product is marked with encrypted data on the diameter and wall thickness, operating pressure, service class, pipe material and much more.

There are several modifications of polypropylene, each of which has its own operating characteristics:

1. PPH – products made from homopolymer, used exclusively in cold water supply.
2. PPV pipes are made of block copolymer, the scope of application is cold water supply and installation of heated floors.
3. PPR is the most common material - a random copolymer of polypropylene, used in the installation of heated floors, for hot water supply and water heating.
4. PPs – polypropylene with improved heat-resistant properties, rarely used in domestic water supply systems.

For cold water supply and drinking water supply, it is enough to use PN10 pipes made of homopolymer, since the low temperature environment practically does not cause linear expansion, and the pressure in the household pipeline is below 1 MPa.

In heating systems and for supplying hot water, it is advisable to install reinforced pipes with fiberglass or aluminum foil (basalt fiber has only recently appeared on the pipe market and has not yet gained much popularity).

Reinforcement in a hot water pipeline is necessary as it restrains the linear expansion of polypropylene and prevents deformation of the pipes. Products with an aluminum layer can be used in any conditions, since the metal foil provides additional rigidity without practically increasing the outer diameter. Fiberglass is best used indoors.

Important! If the pipeline section will pass through open air, it must be protected from ultraviolet rays. The ideal solution would be to use a polyurethane foam shell.

Kinds

Which variety is best to buy depends on many factors, including the scope of application. But first it’s worth finding out what products are produced. Popular models are available without reinforcement and reinforced. The last option is divided into the following groups:

1. Fiberglass reinforced. They are characterized by high rigidity and low thermal expansion.
2. Reinforced with aluminum foil (perforated or solid). In production, a static polypropylene copolymer is used. They come in gray color. Quite durable. They have automatic stabilization.
3. Reinforced with basalt fiber. The reinforcing layer is basalt. A distinctive feature is heat resistance and resistance to pressure changes.

You can find both smooth and corrugated designs on the market. Corrugated products with large diameters are used for sewerage equipment, drainage systems, drainage of rainwater and groundwater. The maximum operating temperature is 60 degrees Celsius. It will briefly reach 100 degrees. No special equipment is used to install the systems. The main advantages of the designs are considered to be:

• significant throughput;
• increased ring rigidity;
• resistance to corrosion and chemical components;
• opposition to the influence of stray currents;
• high hydroabrasive wear;
• long service life.

The main reasons for choosing polypropylene pipes for the heating circuit

The reasons, which, in fact, are the advantages of polypropylene pipes are as follows:

• Polypropylene has a distinctly low weight, which greatly simplifies its delivery to the work site and installation itself - no special devices or equipment are required.
• If you have the necessary tools, polypropylene pipes are easy to install, and welding techniques can be learned very quickly.
• The manufacturing material is absolutely harmless for residential premises, since it does not change its chemical composition even with strong heating and does not emit toxic fumes into the air.
• Thanks to the stabilizers included in polypropylene, pipes can withstand water hammer and thermal loads, and even freezing of water inside without rupture.
• The smooth inner walls of the pipes promote uniform, turbulence-free and noise-free circulation of the coolant.
• Both the pipes themselves and their components are inexpensive. A wide selection of components allows for installation of a circuit of any complexity.

A little training and any owner can carry out independent installation

• A circuit made of high-quality pipes, if installed correctly, will last at least 20–30 years.
• The aesthetic appearance of the pipes makes it possible not to spoil the interior, and the contour itself usually does not require either painting or additional decoration.

So, polypropylene pipes with a reinforcing aluminum layer are excellent for heating circuits of autonomous and central systems. In addition, the installation of this material is quite simple and feasible even for people who have no experience in such work. After several training sessions on the installation of individual components, the assembly process of the entire circuit can be carried out on your own.

Which PPR pipes are more convenient to install?

The easiest and fastest way to install, of course, is single-layer polypropylene pipes. For installation it is enough:

• cut the product with a hacksaw or pipe cutter,
• rub away burrs on the edges,
• connect structural elements using a fitting or special glue (liquid welding).

We recommend that you read: Replacing old pipes with polypropylene on your own

The principle of installing multilayer PPR pipes is the same, however, in this case cold welding is not suitable, since it will only glue the outer layers and will not provide a reliable connection.

Therefore, multilayer pipes are best connected by hot welding or using special multilayer threaded fittings.

Attention! Do not attempt to thread a pipe or fitting yourself. There is a high probability that the resulting threads will not match, which means the connection will not be airtight. It is better to buy fittings with ready-made standard threads.

Pipes with aluminum reinforcement require special preparation before installation. If layers of fiberglass pipes are literally soldered into each other, then aluminum foil is connected to polypropylene using glue, which means there is a possibility of delamination.

To avoid this negative consequence, before welding PPR pipes with aluminum reinforcement, it is necessary to remove a small section of foil and solder the inner and outer layers of polypropylene together. Thanks to this action, water will not be able to penetrate between the layers, which means there will be no threat of deformation and destruction of the pipeline.

Fittings for water supply system made of PP pipes

The name “fitting” itself comes from the English “fit”, which in translation sounds like “to assemble”. With their help, pipes are joined in a straight line, at an angle, and form contours and branches. In this case, the pipeline can include both pipes of the same diameter and different ones.

Many enterprises produce polypropylene pipes; they are constantly expanding their range of products. It includes both simple and complex fittings for polypropylene pipes. These elements for connecting pipes are threaded, crimped, and welded.

The water supply system is created using the following types:

• couplings;
• corners;
• tees, crosses;
• sweeps;
• adapters.

The first of them, with a barrel-shaped geometry, is the simplest. The internal diameter of the “barrel” is identical to the external diameter of the pipe. Its purpose is to connect pipes of equal cross-section. The water pipeline requires complete tightness; only welding can provide it.

The process of welding polypropylene pipes is quite possible to do independently. All work does not involve any heavy physical effort

To do this, the connecting elements must be made of the same material as the PPT. Since these parts are bell-shaped, they are put on the pipe. The connection occurs after heating the two parts. If unheated pipe can be inserted into the fitting, it is not suitable for piping installation.

Classification of fittings for PP pipelines

The material from which polypropylene fittings are made may have a different composition, which affects thermal stability.

Based on this feature, there are 3 types:

• homopropylene - abbreviated as PPG, marking - RRN, PP-1;
• block copolymer - denoted by the abbreviation PPV, markings - PPV, PP-S, PP-2;
• round copolymer - PPR, labeled - PP-3, PPRC, PPCR.

The first type is polypropylene with the inclusion of special modifying additives - nucleators, fire retardants, antiseptics. They impart a certain set of properties to the final product. Both pipes of this type and fittings are suitable exclusively for cold water supply.

The second is a polymer made up of homopolymer micromolecules arranged in a precise order. The finished product made from this material has high impact resistance. Since it can withstand high temperatures, it is suitable for hot water pipes.

Polypropylene has high impact strength. It is resistant to abrasion and bending. Has excellent dielectric characteristics, low gas and vapor permeability

The structure of the rondom copolymer is crystalline. The product does not lose its properties over a wide temperature range - -170 - 1400⁰. Elements made of this material can have a cross-section from 1.6 to 11 cm. They are used in many engineering networks. The characteristics of polypropylene also include such a parameter as MRS. This is a characteristic of the shortest duration of strength.

It is related to the maximum permissible pressure in the line. This pressure is guaranteed to ensure the impeccable service of the pipeline when transporting water with a temperature of 20⁰ for 50 years. The indicator is directly related to the thickness of the pipe wall.

Pressure values ​​are encoded in the abbreviation PN with a digital prefix. It indicates the maximum permissible pressure during operation. The higher the digital designation, the greater the pressure load the pipe can withstand.

Examples: PN10 - a pipe with a designated pressure of 10 bar, a pressure of 16 bar corresponds to a PN16 pipe.

You can select both connecting elements and pipes for assembling heating and plumbing systems made of polypropylene according to their intended purpose:

• for passing cold water;
• for transporting hot (maximum 70⁰) water.

There are also pipes used to create heating systems: low-temperature (maximum 60⁰) floor systems and radiator systems up to 90⁰.

Features of polypropylene couplings

PP couplings have thickened walls. The pipes are inserted into the coupling joint using some effort.

Installation of a fitting with a diameter less than 5 cm is performed manually. Before connecting pipes using fittings, the pipes are cut at right angles and burrs are removed

The main thing is that the part of the pipe that gets into the coupling is absolutely smooth. The pipe is inserted into the connecting element until it stops, after fitting it is removed and heated on a welding iron to firmly and hermetically connect the parts of the PP pipeline.

Transition elements for products of different diameters

Products of different sections are connected using a special type of adapters. It performs the same role as the coupling, but connects different diameters. If you need to continue the polypropylene pipe with a metal one, these connecting elements are also used.

In this case, they differ from simple couplings in the presence of an internal thread on one side. This adapter hermetically connects smooth sections of the water main.

Corners and their scope of application

Plumbing is not always a perfect straight line. Sometimes it becomes necessary to form a right angle. Polypropylene is a rigid material and inflexible in working condition. But it can be bent if only preheated. Another thing is that you don’t need to do this.

If a polypropylene pipe is heated and then bent, the outer wall at the bend will become thinner. This will worsen the strength characteristics of the entire system. Folds will appear on the other side of the pipe, reducing its throughput.

When the design temperatures and pressures increase slightly, a leak may occur. The best solution in this situation is to use a fitting bent at the appropriate angle.

The bending angle is 45, 90⁰. There are corners with carvings on one side. So, when installing a faucet in a bathroom, use a corner with a cross-section of 2 cm on one side and a 3-quarter internal thread on the other.

Using tees and crosses

In situations where it is necessary to bring together more than two bends, tees and crosses are used. For example, it is necessary to supply water from the riser to the bathroom or to the kitchen sink.

Such fittings have many modifications. Some pipes run at a 90⁰ angle, others at an acute angle. To install shut-off valves on connections of this kind, fittings are produced with threads on one side. The second side is intended for welding.

The use of tees and crosses allows you to quickly and efficiently assemble polypropylene pipeline branches. To install shut-off valves in plastic pipelines, fittings are produced, one of the sides of which is equipped with a metal thread

The temperature and heating time of polypropylene parts are strictly regulated. The following article will introduce you to these values, in which, in addition to these important parameters, you will find a detailed guide to connecting PP parts by soldering.

Bypass elements for water mains

In the case of laying a water pipeline passing along a complex trajectory, it is impossible to do without bypass curved parts. They are necessary when the pipe needs to be laid to bypass obstacles located near the wall. They change the direction of the highway smoothly.

Visually, these parts are similar to squares, but their bend is more round. With their help, it is possible to rotate the water supply by 120⁰.

The bypass element is mounted using socket welding. The bypass ring is compatible with solid polypropylene pipes, as well as with reinforced reinforcement frames

They produce polypropylene bypass fittings from PPR brand PP. Such elements also fit well into corner joints, and this is important when communications are located externally.

Correct selection of fittings by diameter

The selection of plastic fittings, as well as the connection method, is carried out based on the material of the pipes. In any case, a diagram is first created, then the type of connecting elements is determined.

Fittings for diffuse welding or soldering are suitable for a system of polypropylene pipes. This is an inexpensive method, but it provides a monolithic and 100% tight connection of polypropylene pipes used in the assembly of heating, sewer and water supply networks of any complexity.

The diameters of the connecting elements are related to the diameter of the pipes. In turn, the latter value is interconnected with such a parameter as the throughput of the water supply system. When selecting the required diameter, you need to take into account several nuances.

The marking of pipe products includes the outer diameter, the value of which also takes into account the rather thick walls of the pipe. Therefore, with the same outer diameter, the permeability of a polypropylene pipe will be less than, for example, a metal-plastic one.

The polypropylene pipe inside is absolutely smooth, as opposed to steel. No deposits linger or accumulate in it. So if initially the internal diameter of this type of pipe was the same, the PP pipe will provide more efficient passage.

The greatest demand is for PP fittings and pipes with a diameter of 20 to 40 mm. There are also plenty of larger size products on the market, but they are not as popular

For water supply in a cottage or apartment with a standard set of water intake points, the best option would be a pipe with a diameter of 20 mm. Large diameters (50 mm) are more suitable for implementing water supply schemes for microdistricts.

Fittings are not needed in this case. Docking is done by welding. To include check valves and gate valves into the system, steel flanges are used.

Applying propylene to the internal surfaces of pipes

We are talking about metal-plastic pipes that have an outer polypropylene layer. They tolerate increases in temperature well.

The disadvantages of these products include the following:

1. The presence of several layers. Three different substances are connected into one structure using an adhesive method.
2. The fitting is attached only to the outer layer, which makes the connection not very strong.
3. The transported medium often comes into direct contact with the reinforcement, which is why the material can gradually wear out.
