| Summary: | The present invention relates to pipes for conveying drinking water and more particularly polyolefin pipes. Mains for distributing drinking water, in particular buried mains are made of polyolefin pipes such as polyethylene or polypropylene. These pipes have many advantages. They do not corrode, they are delivered as coils of great length; it suffices to unroll them.
The invention relates to pipes for conveying drinking water, including a main layer made of polyolefin covered on the outside with a layer of a thermoplastic polymer which is impervious to hydrocarbons, such as, for example, polyamides, polyvinylidene fluoride, ethyl/vinyl alcohol copolymers or polyesters. These pipes are particularly useful for pipes buried in soils that may be contaminated with hydrocarbons. |
