Square and Rectangle Pipe Mill Machines Direct Forming Shape type This square and rectangle pipe mill line adopts the multipoint bending combined type forming technology, make the steel strip into square or rectangle pipe directly. Compared with traditional technology, this have the following advantages: One set of mould can produce all size of square and rectangle pipe; The output pipesl have good appearance; Cut down the cost of machine; Shorten the time of adjusting the mould; Decrease the forming resistance strength; Lighten the mould wear; Reduce the load of power utilizaton. Main Technical Processing Flow:
