ERW API Steel Tube Making Machine No Need Change Rollers ZTF Pipe Mill

ERW114 high frequency longitudinal welded pipe production line / pipe making machine / tube mill is designed to produce welded pipes of 48mm-114mm in OD and 1.5mm-4.5mm in wall thickness, as well as corresponding square and rectangular tube.

Advantage:

Low wastage, low unit wastage and low production cost.
High yielding, the machine works stably at a high speed, which improves the yielding of products.

High production efficiency, line speed can be up to 120m/min.
High accuracy, diameter error is only 0.5/100 of the pipe OD.

Products: architectural structure tubes, low-pressure liquid tubes, coal transmission belt tubes, drive shaft tubes, guardrail tubes, tower footing tubes, automobile beam steel tube and other products.
