Product Description

Product Description

PE-RT is the abbreviation of Polyethylene of raised temperature resistance . It is a non-cross-linked polyethylene that can be used for hot water pipes, also known as " high temperature resistant non-cross-linked polyethylene " . It is a medium-density polyethylene produced by special molecular design and synthesis process, which improves the heat resistance of PE . It retains the good flexibility, high thermal conductivity and inertness of PE , while making it more pressure-resistant. PE-RT pipes can be used for all use levels of hot water pipes specified in ISO10508 .

Production features

Product Introduction

PE-RT pipes and fittings are high-temperature resistant pipe systems produced in accordance with CJ/T175-2002 using ethylene - octene copolymer as the main raw material . The raw materials used have a unique molecular structure and good water pressure resistance. It has particularly good softness, is easy to bend without deformation during construction, has outstanding low-temperature impact resistance , is safe and hygienic, has hot-melt connection, reliable interface and never leaks. It is an ideal pipe for low-temperature hot water floor radiant heating .

Low-temperature hot water floor radiant heating is an ideal heating method. It uses low-temperature hot water as a heat medium, heats the floor through plastic pipes buried in the floor, and radiates heat evenly into the room. It is an energy-saving heating system that regulates the room's microclimate.

Low-temperature hot water floor radiant heating successfully solves the problem of heat source tension in high-space, large-span, and low-window buildings, improves heating comfort, and gives people a comfortable feeling of warm feet and cool head , which is in line with the physiological regulation of the human body. Features: It promotes blood circulation in the human body, while also reducing floor noise, realizing automatic temperature control for households and rooms, eliminating dust and odors in cooling equipment, and has a service life of more than 50 years.

PE-RT floor heating pipe >> Performance characteristics

1. Light weight, easy to transport and install.
   2.Good flexibility, making it convenient and economical to lay. Recyclable and meets environmental requirements;
   3. When the pipe is bent, the stress in the bent part can be relaxed quickly without " rebound " phenomenon, which facilitates construction operations and avoids bending of the pipe due to stress concentration during use. The phenomenon of damage occurs at various places;
   4. The friction loss in the pipe is small, and the fluid transport capacity of the pipe is 10% greater than that of the PE-X pipe of the same diameter ; 5. The brittle temperature is low, and the pipe has excellent low-temperature properties, so it can be used under low temperature conditions in winter It can also be constructed, and no preheating is required when bending the pipe, which can solve the economic losses caused by the low winter temperature in northern and the inability to construct. The minimum bending radius is 5 times the outer diameter of the pipe; 6. Chemical resistance Good corrosion resistance, no rust, long service life. After several years of use of general steel pipes, the inner wall of the pipe becomes rough due to severe corrosion, and the flow resistance increases, thereby greatly reducing the water transport capacity; 8. Under the conditions of an operating temperature of 70°C and a pressure of 0.82MPa , the pipe can be used safely for 50 years. Above; 9. No toxic additives are added to the pipe 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; 10. The impact resistance is 2nd of that of PE-X pipes times ; 11. Good heat dissipation performance, thermal conductivity is 0.4 W/ ( m·K ), which can save a lot of energy in heating applications, so the use of PE-RT in the heating field can better exert its excellent characteristics; 12. Weldability : After the system pipeline is damaged, it can be repaired by socket hot fusion welding or electric fusion welding.

FAQ

Q1: What about the sample?
A1: Our sample is usually well prepared and coated well, and delivered to customers by international courier(DHL, FedEx, TNT etc.) .

Q2: What about your payment terms?
A2: We usually use T/T payment term, but L/C is also fine. In the future, we will continue to support other payment terms.

Q3: How long is the expected delivery time of the product?
A3: We will complete orders below 10,000 meters within 15 working days, and the final arrival time will be affected by the shipping date.

Q4: Could you use our labels or printings instead of yours? (ODM)
A4: Yes, it depends on the requests of customer. But important data must be printed on the pipe such as outer diameter, wall thickness, PN data, SDR data, Production standard, Place of origin and date of production.

Q5: Could you offer special package services?
A5: Yes. We could offer the package on customer' s requests. It might have some extra fees.

Q6: What is the service life of your product?
A6: The service life should be 50 years.But you must follow our correct storage and construction precautions, otherwise the consequences need to be borne by yourself.

Q7: How could you guarantee the quality of you product?
A7: We could offer MSDS, COA, TDS files on customer' s requests and charge for additional charges. In addition, we'll take random samples and analyze them.
