摘要： A tool comprises a plug (10) for fitting in a pipe end. A screw (12) is threaded in the plug (10) for advancement into the pipe. An arm (14) is pivotted with respect to the screw (12) and biassed towards the outside of the pipe. A cutter disc (20) is fast on the arm (14) and provided with a peripheral slot (22) leaving an edge (24) for cutting the outside of the pipe. The slot (22) extends over only a portion of the thickness of the disc (20) nearer the end of the pipe. The tool is suitable for removing a thin layer from the outside of a plastics pipe before thermofusion.

摘要： The method of forming a welded joint between an end of a thermoplastic pipe like member and a surrounding pipe fitting including a thermoplastic sleeve, comprises the steps of forming around the internal wall (2) of the sleeve a helical cut, said cut being inclined to the surface of the wall along the line of cut, and the cutting tool and its angular relationship to the bore of the fitting being chosen such that during incision an internally extending flap of the thermoplastic material produced by the incision is caused to open out and deform transverse to the direction of incision whereby a helical cavity is formed within the sleeve wall; feeding into said cavity an electrically conducting wire; (5) working the internal wall of the sleeve so as to lay, at least partially, the flap against that wall and enclose the wire within the cavity between the flap and the sleeve wall; fitting the sleeve about the end of the pipe or pipe like member; and passing an electrical current through the electrical wire so as to fuse the sleeve to the pipe or pipe like member.
