Abstract: A polyethylene pipeline including a plurality of prefabricated pipes of predetermined diameter fused on one end to respective bell fittings to form prefabricated bell and spigot pipe assemblies. The bell connector includes an enlarged in diameter bell connector formed with a socket having an internal diameter for telescopical receipt of the second end of the adjoining pipe length and includes an increased in diameter interior gland for receipt of a helical heating coil. The heating coil is constructed of an electrical resistant wire coated with an electrical insulative coating which is, in turn, coated with a medium density polyethylene coating. The terminal ends of the wire is coupled with electrical connectors protruding to the outside of the bell connector.
