Title:
ELECTROMAGNETIC BOND WELDING OF THERMOPLASTIC PIPE DISTRIBUTION SYSTEMS
Document Type and Number:
WIPO Patent Application WO/2010/033163
Kind Code:
A3
Abstract:
A thermoplastic pipe distribution system is assembled by electromagnetic bond welding of a thermoplastic pipe (310,410,516) to a thermoplastic fusion pipe joint assembly (652) comprising a threaded fusion pipe ring (330, 330a, 430, 504, 514), a threaded fusion pipe socket (350,450,502,512), and a susceptor layer between the fusion pipe ring and the fusion pipe socket. The fusion pipe ring is screwed into the fusion pipe socket, and the pipe is inserted into the fusion pipe ring. An induction coil (112) is placed around the fusion pipe socket. Radiated electromagnetic energy heats the susceptor layer to melt at least a portion of the susceptor layer, at least a portion of the fusion pipe ring, at least a portion of the fusion pipe socket, and at least a portion of the pipe. The fusion pipe ring is further screwed in to compress the molten material. The joint is then cooled to solidify the molten material.
