METHOD OF APPLYING MULTILAYER ANTI-CORROSION COATING ON PIPE SURFACE

摘要

A method of applying a multilayer anti-corrosion coating on a pipe surface provides helical winding extruded melt films of adhesive and polyethylene followed by rolling by a roller to the heated pipe. On the pipe surface a layer of molten polyethylene in the form of a film is wound, on which a layer of adhesive is applied. The layer of adhesive is applied in such a way that its edge goes beyond the edge of polyethylene film.
