Pe rt pipes made of heat-resistant plastic. PE-RT pipes type II. Maximum deviation, mm
We always want to start a text in a non-trivial way. And here is just another opportunity and that same case. Due to the fact that the price list for this system is limited to only two positions - you should not expect multi-letter texts in the description, but it is better to immediately familiarize yourself with the prices we offer.
The material for the manufacture of PE-RT pipes (polyethylene with high temperature resistance) is a copolymer of polyethylene with octene, characterized by increased temperature resistance. Heat-stable polyethylene still welds and processes well hand tools; being flexible, it withstands pressure well and has many characteristics superior to the previous cross-linked one (PE-X).
Difference polyethylene PE-RT from polyethylene PE-X in the molecular structure of the pipe. PE-RT has a larger number of carbon bonds and does not require the introduction of additional components for cross-linking (silanes or peroxides) of molecules during production, which makes the structure of the material homogeneous.
PE-RT pipes are better than PE-X:
- More flexible at temperatures close to zero;
- They are characterized by a homogeneous material structure;
- Many connection options (butt welding, press connections, compression, sleeve welding);
- Recyclable;
- Does not require laboratory testing of the degree of crosslinking.
- They have better thermal conductivity compared to PE-X. PE-Xa has 0.324 W/m, PE-RT has 0.344 W/m.
PE-RT pipes are better than PP-R:
- Withstands high pressures and more long time at higher temperatures than PP-R pipes;
- They have better thermal conductivity compared to PP-R (PP-RCT, PP-R Beta). PP-R - 0.206 W/m, PE-RT - 0.344 W/m;
- Big throughput pipes with equal diameters.
Distinctive characteristics of PE-RT pipes:
- have high mechanical strength to external influences;
- Working temperature is 70 °C with a maximum of +90 °C;
- Maintainability;
- Light weight;
- Low noise (regardless of the fluid flow rate in the pipeline).
Single layer pipes
Yes, you guessed it - consisting of one layer, i.e. monolayer. SLT Aqua PE-RT pipes are produced in various standard sizes.
They are intended for installation:
- Underfloor heating;
- Cold and hot water supply;
- Radiator heating;
- Snow melting systems;
- Technological pipelines.
The exceptional flexibility of the material and high thermal conductivity make it possible to install complex systems without losing the functional properties of the pipeline and maintaining maximum heat transfer.
Pipes can be produced in diameters of 10, 12, 16, 20, 25 and 32, 40 and 50 mm with a wall thickness of 2 mm and above. The SLT Aqua company produces PE-RT pipes in two sizes: 16x2.0 mm and 20x2.0 mm. The starting material is LG Chem SP980 raw material.
The PE-RT pipe with a diameter of 16 mm and a wall thickness of 2 mm, used for the installation of water heated floor systems, heating systems, hot water supply and hot water supply, has a mass of only 0.085 kg/m and can be bent with a radius of curvature of up to 80 mm.
Anti-diffusion coating - a layer of ethylene-vinyl-alcohol EVOH (or EVAL) is applied to the outer surface of the main body of the pipe or its inner part.
The presence of an oxygen barrier in pipes is not prerequisite application and refers to an additional, although not mandatory, measure to protect the system from oxygen penetration. Modern systems reliably protected from contact with external air, therefore, as a rule, they do not need additional protection. That is why we recommend SLT AQUA pipes specifically for the installation of heated floors. They do not contain an oxygen barrier, but this does not affect the mechanical, thermal and chemical characteristics pipes, but reduces their cost and weight. Take this into account, since only 4% of oxygen passes through the surface of the pipes, and the remaining 96% passes through the threaded connections.
The distinctive color of such pipes is red. You can buy them in coils of lengths of 100 m, 150 m and 200 m. On request, we can supply pipes in coils of up to 600 m. The greatest demand is for PE-RT pipes for heated floors 20x2 mm and 16x2 mm. They are connected using brass and polyphenylsulfone press and compression fittings- methods for fastening familiar to plastic pipes, as well as welding methods - socket and butt (electric welded fittings are not yet available). This makes them the most convenient to use and almost universal.

PE-RT- it is modern and versatile polymer material, characterized by a large margin of safety and high resistance to temperature influences. Pipes from PE-RT type and 2 can be used for heating, cold and hot water supply. They are also widely used to protect power supply and communication cables. Compared to other types of polyethylene pipes, products made from PE-RT type 2 have the following advantages:
Widest operating temperature range. Permissible constant temperature of the coolant is 95°C. At the same time, flexibility is maintained sub-zero temperatures, down to -50°C, which eliminates the formation of cracks during storage and transportation in winter time. When the water inside freezes, the pipes are also not damaged; after defrosting, they retain their original shape.
Resistant to corrosion and chemical attack. Pipes made of PE-RT are not affected by hard water and can withstand acidic and alkaline environments. Deposits do not form on the walls of polyethylene pipes, reducing throughput.
Flexibility and elasticity. Pipes of small diameters are suitable for hidden wiring and can be concreted. PE-RT pipes with a diameter of up to 110 mm inclusive can be supplied in coils, which allows such pipes to be laid using the trenchless method, as well as inside old metal pipelines without dismantling them.
High operating pressure. For pipes with sufficient wall thickness, the nominal operating pressure is 16 atmospheres at a temperature of the transmitted medium up to 95°C. Thin-walled pipes are designed for constant pressure up to 10 atmospheres.
Fast installation. The length of the section in the bay allows you to do without intermediate connections. This also reduces the amount of waste.
Low thermal conductivity allows minimizing heat loss in heating networks.
Reliable connection. PE-RT pipes can be welded just like any other polyethylene pipes- end-to-end or using electric welded fittings.
Using PE-RT pipes for cable laying
Type II PE-RT pipes are often used for cable installation. In this case, they can be used as standard pipes, and pipes specially designed for this purpose with an additional protective layer.
Manufacturers offer several options for pipes designed for laying power, telecommunications and signal cables, as well as fiber optic lines. For example, the Tekhstroy company produces a series of TEHSTROY TR (temperature resistant) pipes made of polyethylene with increased heat resistance. High stability to temperature fluctuations allows you to lay a pipe at any depth, including above the depth of soil freezing. Operating temperature ranges from -20°C to +95°C.
The TEHSTROY TR series includes single-layer pipes with a nominal outer diameter Dn and pipes with an additional protective layer, sold under the brand Technical Construction TR-1 Prosafe. The protective shell, made of thermoplastic polymer, may have a red or green color. Both types of pipes are available in diameters from 16 to 630 mm, which allows you to choose the optimal size for both mains and single signal and communication lines.
The use of pipes with a protective layer allows pipelines to be laid directly into the ground, as well as along the bottom of reservoirs with or without burial into the ground. Using the HDD method often reduces installation costs, since it does not require earthworks and greatly reduces the number of joints.
Pipe Thermotech Thermosystem® (old name Thermotech >MIDI< Composite) является модернизированным вариантом труб PE-RT, полностью изготовленной из материала Dowlex 2344 (тип 1) и 2388 (тип 2) (PE-RT, trademark Dowlex is owned by DOW Chemical Corp.) with a large number bonds between molecules, with an oxygen barrier (EVOH) hidden inside the pipe between layers of polyethylene. Because All layers are polymers, then as a result of sequential connection of layers, a pipe is formed as a single whole, stable under conditions of temperature and pressure fluctuations, with a small linear elongation, resistant to mechanical stress.
Let's decipher the abbreviation PE-RT - PolyEthylene of Raised Temperature resistance - polyethylene of increased heat resistance - the secret lies in the large number of carbon bonds in the molecules. The side chains of the linear Standard Polyethylene (PE) molecule are formed by a combination of butene molecules. Two carbon atoms are used to connect the main chains to each other, so the probability of intertwining is low. The side chains of the linear PE-RT polyethylene molecule increase the number of connecting Carbon atoms to 6, while the degree of intertwining is much higher. If the source material for PEX - Polyethylene, with the same monomer content, is not “cross-linked”, then it will provide much less strength under prolonged exposure to pressure.
Warm floor pipe Thermotech Thermosystem®– has an anti-diffusion layer OXYDEX (EVOH polyethylene), which prevents the penetration of oxygen and an anti-creaking layer, which form a single whole with the pipe.
Anti-diffusion layer OXYDEХ: During the production of pipes, a thin layer of modified polyethylene, 0.1 mm thick, is applied to the surface of the “main” PE-RT pipe. This is followed by the same layer of EVOH (ethyl vinyl hydroxide) plastic. Previously, this anti-diffusion layer was applied on the outside of the pipe. Over time, some manufacturers and Thermotech pipes, incl. They began to apply another protective layer of polyethylene on it.
New polymer pipes from Thermotech - ThermoSystem pipes made of PE-RT type II polyethylene - are more flexible and more reliable compared to the old ThermoSystem pipes (12, 17 and 20 mm) due to the placement of an anti-diffusion layer on the inner surface of the pipe with a protective layer polyethylene. The oxygen barrier is protected from mechanical damage by the entire thickness of the pipe wall
The EVOH layer acts as a diffusion barrier for oxygen, and the polyethylene layer increases the adhesion between the pipe and the diffusion barrier. The barrier is tightly glued to the pipe, making bends of small radii possible without the formation of folds. Oxygen-tightness of pipes Thermotech complies with the DIN 4726 standard (Deutsches Institut fur Normung), and is less than 0.1 g/m2. for 24 hours at 40 °C. OXYDEX layer in pipes Thermotech reliably protected from mechanical damage by a protective layer of polyethylene. The melting point of the anti-diffusion layer is 180° C. These properties allow the use of such pipes at operating temperatures of the carrier up to 95°, and in short-term modes – up to 110° C, that is, mainly in hot water supply and heating systems, heated floors.
Oxygen penetrating the system does not cause any harm to the pipes themselves; it only reacts with the metal parts of the system, causing accelerated corrosion of heating boilers, pumps, radiators, shut-off and control valves and other metal equipment. This process is especially accelerated when using pipes in systems with elevated temperatures, i.e. in heating systems (especially radiator systems). Unfortunately, it is not included in SNiP permissible value oxygen penetration in plastic pipe systems. Therefore, in reality, pipes without a diffusion layer are often used, which after 5 years leads to the failure of the steel elements of the system. To prevent this from happening, it is necessary to use only pipes in heating systems that meet the requirements of the German standard DIN 4726. It should be noted that today only a few companies can offer pipes that meet the requirements of this standard.
This pipe can withstand high pressures. The service life of PERT pipes is determined by nomograms depending on temperature and pressure working environment(as well as all other polymer pipes). According to Russian certification, PE-RT pipes are classified as type “t” (heavy), i.e. withstanding pressure of 20 kgf/cm2.
The THERMOTECH brand produces 5-layer unreinforced pipes for heating and water supply systems:
- Thermotech Thermosystem PE-RT I diameters 8x1, 12x2 mm, 17x2 mm, 26x3 mm
- Thermotech MultiPipe PE-RT II diameters 16x2, 26x3,
- Thermotech Thermosystem PE-RT II diameter 20x2, 32x3 mm
Advantages of Thermotech pipe
Thermotech = reliable + easy to install + inexpensive!
Extreme flexibility and strength without the use of a crosslinker. The secret lies in the large number of carbon bonds in the molecules. To understand the difference, answer the question: what kind of shoes do you prefer to buy - with edging sewn to the sole (analogous to molecular cross-linking of polyethylene) or with a glued sole (analogous to chemical cross-linking of polyethylene or glued plastics)?
The service life of the pipe is over 50 years. It requires virtually no maintenance during operation, which further facilitates the work of public utilities.
Able to withstand high pressures and temperatures. The service life of PERT pipes is determined by nomograms (see appendix) depending on the temperature and pressure of the working medium. According to Russian certification, PE-RT pipes are classified as type “t” (heavy), i.e. withstand pressure 20 kgf/cm2
Polyethylene pipes are 5–7 times lighter than steel pipes. Pipes are produced seamlessly in standard coils 12 * 2.0 mm (1000 m), 16 * 2.0 mm (750 m), 20 * 2.0 mm (650 m), 25 * 2.3 mm (350 m), 32 *3.0 mm (50 m). This significantly reduces transportation costs and makes the work of installers easier.
The temperature linear expansion of PE-RT pipes is several times less than that of standard PEX pipes. When the temperature changes by 50°C, the linear elongation of PE-RT pipes is only 0.3%, and when the temperature changes by 90°C – 0.7%. When cooled, the pipe completely returns to its original shape.
Joining polyethylene pipes is much cheaper, simpler and takes less time. The pipes are connected using brass compression fittings and takes seconds. The entire installer's tool consists of pruning shears and wrench. Therefore, even a non-specialist can change or install the plumbing himself.
No squeaking in underfloor water heating systems.
Due to the low surface roughness (0.125 microns), the pipes are not subject to overgrowing, therefore require virtually no maintenance during operation and are silent at almost any flow rate.
Frost-resistant and able to withstand several freeze-thaw cycles (for example, water).
It has high maintainability. Multiple joining and undocking of the fitting is allowed, while the pipe at the joint retains its properties.
Can be used for transportation food products, aggressive liquids and gases.
Fully meet the requirements of modern industry for the aesthetics of work and operation of pipelines.
Warranty periods: shelf life 3 years, service life 7 years.
The pipe is resistant to impact chemical substances and mechanical wear.

How do pipes for heated floors behave at subzero temperatures? We do not object to the use of pipes in conditions with low temperatures. Moreover, well-known facilities with PE-RT pipes have been operated without problems for years in arenas with artificial ice in Europe.
PERT pipes maintain high strength even at temperatures down to -40°C.
The DOWLEX 2344E material, compared to other polymers, has higher thermal conductivity at negative temperatures (2-3 times higher), which means more power refrigeration units may be reduced.
In Thermotech pipes inner surface- mirror-like, they have a very low roughness (0.125 microns, class 10), this is less than PEX pipes and significantly less than any metal-plastic pipes. The thing is that in metal plastic pipes The main load is borne by the aluminum layer and therefore the polymer layers in such pipes are of worse quality than in plastic pipes. Reducing hydraulic losses in Thermotech pipes will reduce the power of circulation pumps.

Differences between pipes >>>
Many private houses are heated using water heated floor systems. This factor is explained by the efficiency of this type of heating. The coolant circulating through the pipeline laid under the floor has a much lower temperature than in radiators. This means that much less energy resources are spent on heating it.
Warm floors do not spoil the interior of the premises at all, since they are hidden from the eyes of others by the finishing coating. And the air, heated over the entire surface of the floor, is always directed upward, creating favorable microclimate, and increasing the level of comfort.
Ideally, the use of such heating systems should be envisaged at the stage of building a house. Otherwise, you will need to carry out calculations and large-scale work that requires certain skills and craftsmanship. In addition to choosing high-quality heating and pumping equipment, it is necessary to pay close attention to the choice of consumables, the main of which is the pipe.
It is a mistake to believe that any pipe can be laid in a concrete screed. Increased demands are placed on this element of the system, since the service life of the heated water floor and the quality of operation of the entire system will depend on it.
And although on construction market This consumable material is presented in a huge assortment; not every one of them meets all quality and safety requirements.
Which pipe is suitable for laying the water circuit and will not only extend its service life, but also save money? What do the designations PEX and PE-RT mean? What are the advantages of PERT polyethylene, which recently appeared on the Russian market?
Requirements for pipes
In most cases, the contours of a water heated floor are filled with a heavy concrete screed, closed finishing. Even after removing tiles or removing part of the laminate, it will be impossible to visually inspect the system for leaks or any other malfunctions.
Therefore, any pipe that is part of a water-heated floor system must meet strict requirements stipulated by the special conditions of its operation.
The main element of water heated floor systems has a standard diameter, which can correspond to the following values:
It should be noted that when using consumables a smaller diameter reduces heat transfer, which leads to a reduction in the distance between the loops of the circuit and, accordingly, to an increase in material consumption. In addition, the small diameter of the pipe leads to overloads of the pumping equipment. It is also inadvisable to use pipes of too large a diameter, since in this case the thickness will increase concrete screed and, as a result, the load on the floor.
DIY water heated floor
What materials are pipes for heated floors made from?
So what material should be preferred when installing water-based floor heating systems? And here you should not rely on sellers’ assurances that all their goods comply necessary requirements. Such carelessness can lead to problems that arise already at the installation stage of the systems.
Several materials are used in the production of pipes for heated floors.
- Polypropylene. This option is the most budget-friendly. And this is perhaps his only positive quality. It will not be possible to mount a circuit from a single piece of pipe, since they are sold in small meters. This material is not highly plastic, so laying the contour is possible only if a large step is observed between the loops. And most importantly, polypropylene has a very low coefficient heat transfer, so the system will be ineffective.
- Metal. Metal pipes can be made of copper and corrugated steel. These materials are of high quality and durability. But their significant disadvantage is high cost, unaffordable for most of the population.
- Polyethylene (PEX and PE-RT). This also includes metal-plastic. In the production of all varieties we use different kinds polyethylene, and each pipe has a special structure and is processed using various technologies. These materials are distinguished by ease of installation, resistance to mechanical and temperature influences, as well as affordable cost.
PEX pipes
First of all, you need to understand what the term “cross-linked polyethylene” or PEX means. Many household items are made from polyethylene. However, in original form this material is sensitive to high temperatures.
And it’s all because of the structure of the material, the molecules of which are not connected to each other in any way. This drawback is eliminated by using a special treatment of polyethylene, which allows the molecules to be “cross-linked”, due to which the polyethylene becomes stable and does not melt under the influence of high temperatures.
Pipes for heated floors
As a result of such processing, the PEX pipe acquires another positive quality, which is the ability to return to its original shape. That is, if during the operation of water heated floor systems the pipe experiences overload or is subject to mechanical stress that changes its position, after reducing the intensity of the load it will take on its originally specified shape.
Cross-linking of polyethylene is done using different technologies, denoted as follows:
It should be noted that when arranging water circuits it is most often used PEX pipe. The next two varieties are used much less frequently due to their lower quality. And PEX-d pipes in last years and are not used at all.
PE-RT polyethylene pipes
The designation on the pipe “PE-RT” means that it is made of polyethylene with increased heat resistance. This concept does not say that cross-linking technology was applied to it, since the unique PE-RT material already has all the necessary qualities. A distinctive feature of the PERT pipe is the possibility of connection in the circuit using welding or fittings. Regardless of the type of work performed, PERT does not lose its strength and ductility.
PERT polyethylene is also used in the production of metal-plastic pipes, distinctive feature which is the presence of an internal aluminum layer. If a PE-RT polyethylene pipe is produced without an internal metal layer, it is protected from oxygen penetration by other means, for example, by an airtight layer of OXYDEX.
A water heated floor mounted from a PERT pipe has higher performance characteristics. This material, unlike PEX, has increased elasticity and the ability to withstand heat up to 124.7°C. Considering the lower cost of production of PE-RT polyethylene, the installation of heated floor systems from PE-RT pipes is somewhat cheaper, while meeting all the requirements for this method heating

General information about PE-RT pipes
PE-RT pipes are manufactured in accordance with technical specifications made of special polyethylene with increased heat resistance. This ensures a wide range of product operating temperatures ranging from - 20°C to +95°C. Short-term exposure to temperatures up to +110°C is allowed without any damage to the integrity or deformation of the existing pipeline.
Service life at correct installation and compliance with operating conditions exceeds 50 years.
Due to its increased resistance to high temperatures, the PE-RT pipe can be successfully used to supply hot water to residential and industrial facilities. PE-RT pipes for cable lines are designed for laying and protecting high-voltage and other lines from mechanical and temperature influences. A protective polypropylene shell provides reliable protection cable from damage during installation and long-term operation.
Due to the flexibility of the heat-resistant PE-RT pipe (RT - resistance rise temperature), it can be laid using a small number of fittings. This significantly reduces the cost, speeds up and simplifies installation work.
A protective coating that is resistant to scratches and significant mechanical damage allows the PE-RT pipe to be laid using both trench and trenchless methods, and connected using fittings by welding.
