square/rectangle steel pipe direct forming equipment adopts combined moulds, multi-points pre-bending method, directly forming process, without taking the main shafts or stands away, moulds can be replaced rapidly, and with low loading. It can save about 60% of expense and time than machinery unit of non-combined mould style. It can produce square/rectangle pipe with average thickness of the four angles, and with high strength. Such machinery units are appropriate for small batches pipes with multi specifications.
