ABSTRACT:
A pipe fitting for pipelines comprises at least one seating (12) for receiving the end of a pipe to be coupled. The seating surface which is intended to come into contact with the surface of the pipe end, is made of a material having a chemical adhesion reaction on reaching of a predetermined temperature and, around the seating (12), the pipe fitting incorporates an electric winding (14) for heating of the material when an electric current passes therethrough in order that said predetermined temperature can be reached. Advantageously, the seating (12) is formed in a sleeve (17) incorporating the electric winding (14) which in turn is incorporated into the pipe fitting body.
