摘要: 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.
