A novel moulding process has been developed at the Wolfson Centre for Materials Processing, Bmnel University, for the production of curvilinear forms of thermoplastic materials. The process has been used with a gas pipe grade of medium density polyethylene to manufacture right-angled elbows of 63mm diameter SDR 11 pipes. These elbows have been mechanically tested and compared with commercially produced straight sections of pipe which were made from the same polyethylene resin as the elbows.
