Product details

PE-RT Type II Heat-resistant Polyethylene Thermal Composite Pipe is a dedicated piping system specially designed for high-temperature heating applications, and is particularly suitable for directly buried pipeline networks. It consists of three layers: an inner working pipe (made of PE-RT Type II material), a middle layer of rigid polyurethane foam insulation, and an outer sheath of high-density polyethylene.

The Lu Yu brand PE-RT material is manufactured via a special molecular design and synthesis process. By controlling the quantity and distribution of side chains, it achieves a unique molecular structure and crystalline microstructure. This endows the material with excellent long-term hydrostatic strength at high temperatures without the need for cross-linking, and it is also known as "heat-resistant non-cross-linked polyethylene".

High quality, high strength, rich application scenarios, can carry out various large, medium and small heating and cooling pipeline laying projects. It is the first choice for insulation projects in the fields of infrastructure construction, heating and other fields.

PERT Type II pipes advantages

1.Superior Quality, 50-Year Service Life

It features excellent thermal stability and long-term pressure resistance (passed the 8760-hour thermal stability test at 110℃), and can withstand high temperatures with a 50-year warranty.

2.Excellent Hydraulic Performance and Low Friction Resistance

The inner wall of the pipe is smooth with low flow resistance, and the equivalent roughness is only 0.01, less than 1/10 of that of ordinary steel pipes. Under the same specific friction resistance and inner diameter, the flow rate of the pipe is more than 1.25 times that of ordinary steel pipes.

ustry piping systems.

3. Lightweight for Easy Construction

Flange connection, electrofusion connection and butt fusion welding technologies are adopted. The pipes are lightweight, enabling convenient construction and high installation efficiency.

4. Corrosion, Acid, Alkali and Salt Resistance

It resists corrosion, acid, alkali and salt erosion. Its smooth inner wall prevents scaling, ensures large water flow rate, and requires no maintenance during later-stage use.

5.Excellent Flexibility

It boasts excellent flexibility with a bending radius less than 5 times the outer diameter of the pipe. In long-distance laying construction, this feature reduces the use of pipe fittings, eliminates the need for compensators, cuts down construction costs and minimizes potential leakage points.

6.Excellent Sanitary Performance

Non-toxic and with excellent sanitary performance, this product has undergone rigorous testing and fully complies with the requirements of national drinking water standards. It is suitable for application in drinking water and food industry piping systems.
