The invention relates to an induction connection sleeve (1) for fusion joining of plastic pipes (2, 3). The induction connection sleeve (1) comprises a sleeve body (9) having a first (5) and a second receiving portion (7) for receiving first (4) and second connection portions (6) of the plastic pipes (2, 3) to be connected, a first induction heating element (12) and a second induction heating element (13). The sleeve body (9) comprises an inner part (10), which inner part (10) forms the two receiving portions (5, 7) and on which the induction heating elements (12, 13) are accommodated in such a way that the recesses (16) of the induction heating elements (12) are penetrated by the inner part (10) and are flush at their outer lateral surfaces (14, 15) with the inner part (10) in the area of the induction heating elements (12, 13). The sleeve body (9) further comprises an outer part (11) which is connected to the inner part (10) in a bonded manner and surrounds the outer lateral surfaces (14, 15) of the induction heating elements (12, 13).

A pipeline system is enclosed including unlined or plastic lined pipes. A mechanical metal to metal connection is employed that can provide a fluid tight seal. A pipe coupling may be employed to span the connection. Plastic lined pipes can have their plastic liners connected to form a fluid tight bladder. Electro-fusion may be employed.

The polymeric pipes reinforced with a metal casing are used for transporting oil and gas, acids, alkali products, drinking water and industrial water, and also in the transportation of aggressive and neutral pulps. A metal-containing polymeric reinforced pipe includes a welded metal casing and a polymeric matrix having an amorphous-phase-based molecular structure. The metal-containing polymeric reinforced pipe is produced by extrusion moulding with simultaneous feeding of a polymer melt and the reinforcing metal casing into the mould cavity, followed by intensive cooling of the internal and external surfaces of the pipe being moulded. The invention increases the quality and endurance limit in the radial direction of the metal-containing polymeric reinforced pipe, productivity of the process for manufacturing the pipe, and also the strength and technological effectiveness of a pipeline constructed from the pipes produced.
