Abstract
An adhesively joined pipe connection comprises a male pipe part and a female pipe part of fiber reinforced plastics, both being provided with a foam plastic insulating layer. The foam plastic layer extends to the front end of the receiving portion of the female pipe part, a heating resistance foil being fixed to the outer side of said receiving portion by means of an adhesive. A sealing sleeve engages sealingly the outer side of tubular casings of the foam plastic layers upon the female and male pipe parts. Connecting wires connected with heating foil extend through the foam plastic layer. A female pipe part of fiber reinforced plastics provided with a foam plastic layer is extending to the free end of a receiving portion and a heating resistance foil fixed to the outer side of said receiving portion. Wires connected to the resistance foil extend through the foam plastic layer.
