COATED POLYMERIC PIPES AND METHOD OF PRODUCING THEM

摘要

An internally coated pipe (10) for CNG distribution or delivery is disclosed, wherein the pipe is made of a thermosetting plastic material (3), and the internal coating is made of a metallic material (5). The thermosetting material (3) provides the required strength for the pipe (10), for handling the pressures to which the pipe will be exposed, e.g. up to 100 bar, whereas the metallic layer (5) provides the required impermeability to the component parts of the CNG.
