ERW20 H.F. Straight Welded Pipe Production Line

Short Description:

ERW20 high frequency longitudinal welded pipe production line / pipe making machine / tube mill is designed to produce welded pipes of 8mm-20mm in OD and 0.5mm-1.5mm 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.

 

√ 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.
