Spin welders / Friction welders for pipe bell welding | |
Corrugated pipe bell welding using frictionFriction welding is a common practice in europe to attach the bells to the end of corrugated pipes. Unlike North America which has adopted in line belling, requiring a liner trimmer, the European standards typically require a thicker bell than is achievable in most corrugating processes. Pipe manufacturers achieve great flexibility when welding a bell as a post corrugating process, achieving more flexibility in pipe lengths, higher corrugator line speeds and a simpler extrusion system. Friction bell welding supplies a high quality belled product, capable of meeting all the European norms. There are two type of welding systems that have evolved, the first developed in Europe has the bell being welded to the outside of the pipe, while the North American developments have the weld being made between the inner wall of the pipe corrugation and the bell flange. Either system has proven to work, but the resulting injection mold costs for the North american bell designs are significantly less than those used in Europe. Spinwelder have been built to be in line with the corrugator, or offset to the extrusion centerline. The line configuration is customer speciffied. Often a spin welding line is supplied with additional material handling such as weld pressure tester and pipe turning. Many spin welder designs are available from Adescor. The high speed double head machines for pipe sizes of 50mm - 120mm OD have been proven to run at line speeds up to 20m/min welding 4m lengths. The largest machine built to date is capable of running to a 1200mm pipe OD. Adescor have a great track record and many happy customers using their equipment.
