Title:
SECURED IN PLACE GASKET FOR SEALING PLASTIC PIPELINES
Document Type and Number:
WIPO Patent Application WO/2014/204592
Kind Code:
A3
Abstract:
A pipe sealing gasket is shown which is designed to be received within a raceway provided within a socket end of a female bell plastic pipe end which is assembled with a mating male pipe end to form a plastic pipe joint. The raceway is preformed about the gasket during the pipe belling operation. The gasket has a rubber body portion which is reinforced by a hard plastic band formed as a series of integral, spaced wedges which are interconnected by a flexible ribbon. The hard plastic band acts to prevent extrusion of the gasket during a variety of pressure conditions as well as preventing displacement during field assembly.
