ABSTRACT:
An ultra-high molecular weight polyethylene thin-wall pipe which is uniform in thickness and free from a folded mark as well as a method of and an apparatus for manufacturing the same. The ultra-high molecular weight polyethylene thin-wall pipe is manufactured by supplying ultra-high molecular weight polyethylene into and melting and kneading, continuously extruding the molten substance of the ultra-high molecular weight polyethylene from a die connected to a screw of the screw extruder to form a cylindrical roughly shaped article, and diametrically expanding the cylindrical roughly extruded article by means of a tapered core and taking up.
