ERW720 H.F. Straight Welded Pipe Production Line
ERW720 high frequency longitudinal welded pipe production line / pipe making machine / tube mill is designed to produce welded pipes of 355mm-720mm in OD and 6.0mm-22.0mm in wall thickness, as well as corresponding square and rectangular pipe.
Products: architectural structure tubes, API pipes and other products.
√ China's largest straight seam welded pipe production line
√ Apply to high strength steel and big thickness
√ Raw material can be steel coil and single plate
√ ZTF forming process save roller up to 60%
√ With direct square forming technology, one set of roller can produce all pipe sizes
√ Electric control and automatic adjustment, high precision,high roller change speed

We are specialized in designing and manufacturing ERW pipe making machine, high speed precision pipe mill, API pipe mill,cold rolled open section steel production line,stainless steel welded pipe making mahcine,slitting line,etc. we have successfully developed Φ20-Φ720 high frequency straight welded pipe production line, LW100-LW2200 multi-functional cold rolled section steel / welded pipe production line, ZJ100-ZJ2200 slitting line, etc.
We insist on “over-investment” in technology development. We have created four generation of ZTF forming technology for round pipe and direct square forming technology for square and rectangular pipe,saving a lot of cost on mould for customer.
