355mm Welded Pipe Frming Machine

Commodity:Welded Pipe Forming Machine The machine not only can produce round pipe, but also can produce square&rectangular pipe

Commodity: Welded Pipe Forming Machine

ERW/API355 pipe production line is used to manufacture welded steel pipe of Φ114mm- Φ355mm with 4.0mm-16.0mm of wall thickness and produce profiled pipe also within the limit of processing round pipe.

 The technical flow of the production line

Feeding strip→Uncoiler→Straightener→Seven roll Flattening→Strip Steel head-tail butt welding→Spiral accumulator→UT Tester→Forming→High-frequency induction welding→External burr Removing→Internal burr Removing→Polishing Roll →Online UT Tester→Post annealing→drawing →Cooling→Sizing→Numerical Control Flying Saw→Pullout roller table(water washing)→Pipe End Flattening→Water Pressure Testing→Weighing and Measuring→Painting and Marking→Packing→Warehousing

 

ZTF Forming Way Advantage:

It can reserve save 60% charge on rollers.

One set of roller can be used to product any round pipe betweenφ114 and φ355 front of closed pore. And roller in front of closed pore neednt be changed. The roller after closed pore need be changed!

It can reduce product period.

It is easier to restore and adjust rolle
