Direct Forming Welded Pipe Production Line
The production of square/rectangular pipes adopt the combined roller and panel construction . One set of roller can cover most of the sizes and share 90% of the roller.The roller adopting the panel construction contact with the strip deformation region, which can reduce the contact area ,the friction and power consumption of forming roller . At the same time it can save about 4% strip width.
Forming Directly To Square Welded Tube Mill Line
In the process of manufacturing square pipes, rectangle pipes with direct shaping and molding technology, combined type rollers are used with pieces structure.
