  • Shaping Of Tube Ends By Bending Or Straightening (AREA)

Abstract

The end (6) of a polyethylene pipe (1) is shaped into a socket by: (a) heating the pipe end (6) to a temp. near the softening point, (b) gripping the heated end in a die (2) having two bore sections (7,8) of different diameter joined by a section (11) of varying diameter, (c) enlarging the pipe end (6) by means of a first plug (3) so as to contact the wider diameter section (8), (d) applying a compressive force to the pipe end (6) to stabilise the section of varying diameter, and (e) cooling the end (6) at a controlled temp..
