Product Performance 
①Superior compression resistance 
Polyethylene PE pipe is connected by electrofusion connection, heat fusion butt joint, heat fusion socket, welding and mechanical fittings, the strength of the interface is higher than the pipe itself, and will not be broken due to soil movement or load. 
②Good environmental adaptability 
In addition to a few strong oxidizing agents, can resist the erosion of a variety of chemical media, without the need for anti-corrosion treatment.It can be used as the transportation pipeline of various industrial fluid mediums. 
③Quake and shock resistance 
Polyethylene PE pipe will not cause pipe rupture when heavy objects are directly pressed through the pipe.In the process of use for the adaptability of the pipeline foundation, the uneven settlement and misalignment of the pipe foundation is not easy to damage, and because of the low requirements of the pipe foundation, can greatly save costs. 
④Excellent scratch resistance 
Polyethylene PE pipe has excellent scratch resistance, and its anti-abrasion performance is better than that of metal pipe, and it is also 4 times longer than the service life of steel pipe when conveying fluid media such as mineral sand, mud, crude oil, and so on. 
⑤Low temperature resistance, frost resistance 
The performance of low temperature resistance of PE pipe is far better than that of other water supply pipe and gas pipe such as PVC-U, and no embrittlement or brittle fracture occurs under very low ambient temperature. 
⑥Good flexibility 
Polyethylene PE pipe has unique flexibility, its elongation at break is more than 500%, the bending radius can be as small as 20-25 times of the direct pipe, it is easy to move, bend and interpenetrate when laying.

Product Performance
①Heat resistance: PE-RT pipe has good heat resistance, can work stably in high temperature environment, suitable for hot water piping system.
② environmental protection: the production process does not add any toxic additives, no pollution, smooth inner wall, no accumulation of scale, no breeding of bacteria, suitable for drinking water transmission.
③ impact resistance and flexibility: PE-RT pipe has good impact resistance and flexibility, easy construction and transportation, bending pressure can quickly relax, there will be no "rebound" phenomenon.
Long-term creep performance: PE-RT pipe has good long-term creep performance, suitable for long-term use of the pipeline system.
