The invention relates to a PE pipe texturing machine, in particular to an improved PE pipe texturing machine which comprises a PE pipe conveying mechanism, a PE pipe extruding mechanism and a PE pipe molding mechanism which are assembled on a frame (1.10) in a sequential connection way; the PE pipe conveying mechanism conveys PE pipes to the PE pipe extruding mechanism, wherein the cross sections of the PE pipes are elliptic after the PE pipes are extruded by the PE pipe extruding mechanism; then the PE pipe molding mechanism presses the PE pipes for forming; and finally, the PE pipes are sent to a maintaining pipeline. The invention has the advantages of compact mechanism, small land occupation, and convenient operation; and by combining mechanics theory, the invention can effectively reduce damage level of tubular products caused by deformation resistance and deformation traction, improves operation efficiency and reduces probability of safe accident occurrence.
