Product Description

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.

Square Tube Mill Machine

Pipe Making Machine



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.
