ABSTRACT:
This disclosure relates to a method of manufacturing a pipe having a rubber lining within a layer of looped fabric and a resin layer.
The method comprises placing a tubular layer of unvulcanized rubber on an expansible mandrel, then wrapping a layer of looped fabric on the rubber layer, with the loops outwardly directed. The mandrel is expanded to draw the looped fabric partially into the rubber, the protruding loops then being impregnated with uncured thermosetting resin, and glass fabric is then wrapped on the resin.
