METHOD OF FORMING A MULTI-LAYER PLASTIC PIPE FOR CONDUCTING FLUIDS, A MULTI-LAYER PLASTIC PIPE FORMED BY THE METHOD, AND A METHOD OF CONNECTING A MULTI-LAYER PLASTIC PIPE

摘要

A method of forming a multi-layer plastic pipe (4) for conducting fluids, a multi-layer plastic pipe formed by the method, and a method of connecting a multi-layer plastic pipe. According to the invention, a core pipe (2) is formed, whose properties correspond to the requirements set by the fluid to be conducted. With a suitable coating method an outer protective layer (3) is formed around the core pipe (2) of such a plastic material, which properties meet the requirements set by the prevailing environment and/or pipelaying procedure.
