Abstract:
Method of bending thermoplastic pipes involving applying a source of heat to those portions of the pipe which are to be fashioned or shaped, applying a bending force to the pipe and cooling the bent pipe. The steps of the method are undertaken at one and the same location while the pipe is internally supported and has one end secured in a fixed position. Apparatus specifically designed to carry out such a method is also included.
