Project Description

ERW 76 Tube Mill Line & Pipe Mill Machine

ERW 76 Tube Mill Line

ERW 76 high frequency longitudinal welded pipe production line tube mill is designed to produce welded pipes of 12.7mm-76mm in OD and 0.7mm-3.0mm in wall thickness, as well as corresponding square and rectangular pipe.

ERW 76 TubePipe Mill Line Advantages

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.
High production efficiency, line speed can be up to 120m/min.
