Abstract

1394317 Grooving pipes JOHNS-MANVILLE CORP 24 Oct 1973 [27 Oct 1972(2)] 49520/73 Heading B5A [Also in Division F2] A self-locking screwed pipe coupling (see Division F2) may be made by moulding. As shown, a p.v.c. pipe 160 is heated to a deformable state and placed on a mandrel 122, having retractable helical ribs 124 in their retracted position. As the ribs are extended radially outwardly against the inner wall of the pipe, flexible diaphragm 146 is filled with water from a supply 148. The pressure of the diaphragm results in sharply defined grooves being moulded in the inner pipe wall. To enable the pipe to be removed from the mandrel, both the ribs and the diaphragm must be retracted.
