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.
Composition: Un-coiler, head straightening machine, active flattening machine, butt shearing and welding machine, material accumulator, forming and sizing machine unit, computerized flying saw, transmit passage, packing machine, high frequency DC drag, whole line electricity.
