IMPROVEMENTS IN OR RELATING TO PIPE FITTINGS

摘要

An electrofusion pipe fitting (1) comprises: a hollow thermoplastic sleeve member (2), an electrical heating element (7) disposed within the hollow sleeve member, electrical terminals (8) disposed on an outer surface of the hollow sleeve member and connected to the electrical heating element, at least one such electrical terminal being disposed in a non-radial direction (11) with respect to the hollow sleeve member. Composite electrofusion fittings are made by joining a plurality of hollow thermoplastic sleeve members, at least two of which have an electrical heating element located about the inner wall thereof, and connecting the electrical heating elements together.
