摘要

The pipe (1) comprises a collection layer (5) based of a polymer, a sub-adjacent internal layer (4) made of same polymer of the collection layer. The collection layer comprises a charge comprising carbon nanopowders, has a concentration of 0.5-10 mass% and a thickness of lower than 4 mm, and is deposited by coating process, wetting, spraying or extrusion process.
