What is PE-RT?
PE-RT
PE-RT is heat-resistant polyethylene, which is the English abbreviation of Polyethylene of raised temperature resistance. It is a non-cross-linked polyethylene that can be used in hot water pipes. Some people highlight its non-cross-linked characteristics and call it ” High temperature resistant non-crosslinked polyethylene”.

It is a medium-density polyethylene produced by a special molecular design and synthesis process. It adopts the method of copolymerization of ethylene and octene and obtains a unique molecular structure by controlling the number and distribution of side chains to improve the resistance of PE. hot sex. Due to the presence of octene short-chain branches, the macromolecules of PE cannot be crystallized in a sheet crystal, but run through several crystals, forming a connection between crystals, which retains the good flexibility of PE, high Thermal conductivity and inertness, while making it better in pressure resistance, this modification method is similar to the common PPR currently on the market. PE-RT pipes can be used for all usage levels of hot water pipes specified in ISO10508.
Introducing PE-RT
PE-RT pipes and fittings are high-temperature-resistant piping systems produced in accordance with CJ/T175-2002 with ethylene-octene copolymer as the main raw material. The raw material it uses has a unique molecular structure, with linear ethylene as the main chain, plus controllable branches, so it has good water pressure resistance. Its softness is particularly good, it is easy to bend and will not deform during construction, it has outstanding low-temperature impact resistance, is safe and hygienic, has hot-melt connections, reliable interfaces, and never leaks. It is an ideal pipe for low-temperature hot water floor radiant heating.
About Temperature
Low-temperature hot water floor radiant heating is an extremely ideal heating method. It uses low-temperature hot water as the heating medium, heats the floor through plastic pipes buried in the floor, and radiates heat evenly to the room. It is an energy-saving heating system that adjusts the microclimate of the room.
Low-temperature hot water floor radiant heating successfully solves the problem of heat source tension in high-space, large-span, and low-window buildings improve the comfort of heating, and gives people a comfortable feeling of warming the feet and cooling the head, which is in line with the physiological adjustment of the human body Features, promote blood circulation of the human body, reduce floor noise at the same time, realize automatic temperature control of households and rooms, eliminate dust and odor of cooling equipment, and have a service life of more than 50 years.
PE-RT floor heating pipe–performance characteristics
1.
Lightweight, easy to transport, and install.
2.
It has good flexibility, which makes it convenient and economical to lay. Recyclable, in line with environmental protection requirements;
3.
When the pipe is bent, the stress in the bending part can be quickly relaxed, and there will be no “rebound” phenomenon, which is convenient for construction and operation, so as to avoid the damage of the pipe at the bend caused by stress concentration during use;
4.
The friction loss in the pipe is small, and the fluid conveying capacity of the pipe is 10% larger than that of PE-X pipe with the same pipe diameter;
5.
The brittle crack temperature is low, and the pipe has excellent low-temperature performance, so it can be constructed under low-temperature conditions in winter, and there is no need to preheat when bending the pipe, which can solve the problem caused by the inability to construct due to the low temperature in winter in northern my country Economic loss, the minimum bending radius is 5 times the outer diameter of the pipe;
6.
Good chemical corrosion resistance, no rust, and long service life. Generally, after several years of use of steel pipes, the inner wall of the pipe becomes rough due to severe corrosion, and the flow resistance increases, which greatly reduces the water delivery capacity;
7.
Under the conditions of a working temperature of 70°C and pressure of 0.82MPa, the pipeline can be safely used for more than 50 years;
The pipe does not add any toxic additives during the production process, the inner wall is smooth, does not scale, does not breed bacteria, and can be safely used in drinking water transportation and other fields;
8.
The impact resistance is twice that of PE-X pipe;
9.
The heat dissipation performance is good, the thermal conductivity is 0.4 W/(m·K), and it can save a lot of energy in heating applications, so the use of PE-RT in the heating field can give full play to its excellent characteristics;
10.
Weldability: After the system pipeline is damaged, it can be repaired by socket hot-melt welding or electric fusion welding.
