High Frequency Welded Tube Mill Line ERW76

ERW76 H.F. Straight Welded Pipe Production Line

ERW76 high frequency longitudinal welded pipe production line / pipe making machine / tube mill is designed to produce welded pipes of 32mm-76mm in OD and 1.2mm-4.0mm in wall thickness, as well as corresponding square and rectangular pipe.

Products: GI, carbon steel and stainless steel tubes for metallurgy, construction, transportation, machinery and vehicle industries.

Equipment advantages

√ High production efficiency, line speed can be up to 120m/min.
√ High yielding, the machine works stably at a high speed, which improves the yielding of products.
√ Low wastage,  low unit wastage and low production cost.
√ High accuracy, diameter error is only 0.5/100 of the pipe OD.
