Abstract: Electromagnetic induction welding of plastic pipe distribution systems including inter alia induction weldable pipe connectors each having at least one induction weldable pipe socket. The induction weldable pipe sockets include a solid metal susceptor sleeve enveloping a plastic solder lining. Electromagnetic induction coil assemblies for clamping on induction weldable pipe sockets.
Abstract: Induction Weldable Pipe Connectors (IWPCs) (400) for electromagnetic induction welding with at least one plastic pipe (30). IWPCs (400) include a tubular induction weldable mounting (401) having an opposite pair of induction weldable sockets (404A, 404B), a tubular cover (406) externally mounted on the induction weldable mounting (401), and a tubular pipe tang (407) internally disposed in one induction weldable socket (404A, 404B) for destining an induction weldable socket (404A, 404B) as an induction weldable pipe socket (408A, 408B) for forced sliding insertion of a pipe end (31) thereinto. The cover (406) includes an opposite pair of thermally insulated induction weldable socket mouth rims (426A, 426B) for entrapping melted solder lining (412) inside the induction weldable mounting (401) during an electromagnetic induction welding operation, thereby ensuring improved welding.
