ERW/API 219 PIPe 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 pipe mill to run continuously by using strip joining and accumulation equipment. Pipe is formed in round shape passing through a set of driven and idler rollers of forming section before welding. In welding section pipe 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 pipe passes through the cooling section. In sizing section, pipe is formed to specified size and converted into specified shape. After sizing, pipe is cut to specified length by using flying cutting equipment and delivered in collecting troughs passing through run out conveyor.


Function

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.
