<p>A heat-fusible pipe fitting (10, 110, 210) comprises a body having a shank (11, 111, 211) therein which is intended for being fitted into one end of a pipe to be jointed and an electric heating winding (16, 116, 216) for melting the body material together with the pipe material on the shank. Thus fluid inside the pipe is prevented from coming into contact with the pipe head. Consequently the heat-fusible pipe fitting is adapted for use with multi-layered pipes. <IMAGE></p> |
