tuyau en PEHD is a type of flexible plastic pipe used for fluid and gas transfer and is often used to replace ageing concrete or steel mains pipelines. Made from the thermoplastic HDPE (high-density polyethylene), its high level of impermeability and strong molecular bond make it suitable for high pressure pipelines.

HDPE Pipe description
HDPE pipe is used across the globe for applications such as water mains, gas mains,sewer mains, slurry transfer lines, rural irrigation, fire system supply lines, electrical and communications conduit, and stormwater and drainage pipes. However, most United States municipal governments restrict its use on public works projects.
Avantages
It can be joined by butt welding, electrofusion welding, socket welding, or extrusion welding.
Itsystems are available for many applications. It is providing for standard trenching of water mains and so on. As well as horizontal drilling for electrical and telecommunications conduits.
It is very durable and flexible. And it can be bent on site to a radius twenty-five times the nominal pipe diameter.
It is well suited to installation in dynamic soils including in earthquake-prone areas. It has very high flow capacity, because of its smooth bore and end-to-end jointing methods.
