ABSTRACT:
A pipe body sheathed with a film of plastic resin. A strip of conductive plastic resin is along the entire length of the pipe body and made integral with the resin film by extrusion. The conductive strip readily discharges static electricity that may develop in a structure made of said pipes. They are connected to have their conductive strips end-to-end, thereby grounding the so built structure.
