ERW508 High Frequency welded pipe production line/ ERW508 High Frequency tube mill line

Raw material (Steel Strip) in form of a coil is uncoiled and feed into forming section passing through the equipment of entry section. Entry section enables the tube mill to run continuously by using strip joining and accumulation equipment. Tube is formed in round shape passing through a set of driven and idler rollers of forming section before welding. In welding section tube is longitudinally welded by using high frequency induction welding method. Outside bead is removed and formed in shape of scrap. The weld seam is ironed and tube passes through the cooling section. In sizing section, tube is formed to specified size and converted into specified shape. After sizing, tube is cut to specified length by using flying cutting equipment and delivered in collecting troughs passing through run out conveyor.

Based on the features of ERW508 High Frequency tube mill line, we design the machine for your reference:

This pipe is used especially for Petroleum, Natural gas, City gas, Pipe network, Chemical industry, Electricity, Steel truss, Water and Gas pipeline; it is widely used for a variety of pressure pipelines
