(EN) ELECTROMAGNETIC INDUCTION WELDING OF PLASTIC PIPE DISTRIBUTION SYSTEMS
(FR) SOUDAGE PAR INDUCTION ÉLECTROMAGNÉTIQUE DE SYSTÈMES DE DISTRIBUTION PAR CONDUITES EN MATIÈRE PLASTIQUE
Abstract
(EN)
Electromagnetic induction welding of plastic pipe distribution sys- tems including inter alia induction weldable pipe connectors (100) each having at least one induction weldable pipe socket (102). The induction weldable pipe sockets (102) include a solid metal susceptor sleeve (104) enveloping a plastic solder lining (103). Electromagnet- ic induction coil assemblies(200) for clamping on induction weldable pipe sockets (100).
