The square/rectangular pipes(square tube making machine) production line adopts the combined roller and roller mat design. One set of roller can be compatible. The sharing rate of the roller is up to 80%. By adjusting roller mat, to reduce time on roll change and improve work efficiency, meanwhile this application also reduces investment on roll. At the same time the technology can save about 4% steel strip.

Description
Principle: This machine is used to produce rectangular and square tube directly, not from round to square.
Advantage:
1. By combined rolls, many size of rectangular and square tube can be shared with one set of roller. It can save cost on roller and reduce time on exchanging roller. .
2. Good appearance, better angle of rectangular and square tube.
3 By advance multi-point bending, avoiding the axial force and ensuring the quality, meanwhile reducing power wastage and roll abrasion.
