Description
ERW50 high frequency longitudinal welded pipe production line / pipe making machine / tube mill is designed to produce welded pipes of 20mm-50mm in OD and 0.8mm-3.0mm 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, diam
eter error is only 0.5/100 of the pipe OD.

Round pipe Cold roll forming process Good roller design
Square & rectangular pipe General round-to-square process Stable forming process
Round to square with turkshead Good pipe quality, reach same wall thickness with round pipe
