| description | An electroweld fitting or electroweld collar for synthetic resin pipes comprising a body of a thermoplastic and/or weldable synthetic resin, on the inner surface of which a heating coil is arranged. In order to weld an electric current is conducted to the heating coil, whereby the material of the body is strongly heated and becomes plastic. The invention solves the problem of reliably applying the contact pressure in the welding zone while using a reduced amount of material. To achieve this it is proposed that a reinforcement in the form of a winding or a tube be arranged on the outer surface of the body and that the thermal coefficient of expansion of the reinforcement be smaller than that of the body. |
