摘要:
A co-extruded multi-layer plastic pipe and method of manufacture are disclosed in which a first extruder melts and extrudes a first plastic material into the outer annulus of a coaxial extrusion die to form an outer pipe layer, and a second extruder melts and extrudes a highly oxidation-resistant plastic material into the inner annulus of said coaxial extrusion die under a blanket of inert gas to create an inner pipe layer, whereby the outer and inner pipe layers are fused together under the protection of the inert gas blanket which prevents premature degradation of the oxidation-resistant inner layer until the finished extruded pipe has cooled and solidified.
