PE-RT heat pipes are made of high-temperature reinforced polyethylene raw materials and have good heat and pressure resistance. They can be used in high-temperature hot water circulation, central heating, thermal transportation and other systems for a long time. They are dimensionally stable under high temperature conditions, not easy to creep, and have a long service life.

The pipe material has excellent flexibility, can be bent without rebound, is convenient in construction and does not require complex cross-linking process. It is environmentally friendly, non-toxic, non-scaling and corrosion-resistant, and can effectively ensure clean water quality. It is connected by hot melt socket, and the interface is firmly sealed and has no hidden danger of leakage. It has the same lifespan as the building.

Widely used in building hot and cold water supply, central heating, floor heating system, industrial high temperature hot water transportation and other fields, it is a safe, energy-saving, stable and reliable new generation of thermal dedicated pipes.
