The ERW tube mill and pipe mill is a series of machines that builds longitudinal weld seam tubes and pipes with steel strips of a certain width.

Tube Applications
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.

Working flow
uncoiling→ leveling → shearing ends and butt-welding → horizontal accumulator→ edge conditioning → strip edge and body ultrasonic testing → roll forming → high-frequency welding → ultrasonic testing for welding seam → post annealing(normalizing)→ cooling(air & water) → removing outside/inside welding seam burrs → sizing → fixed length flying saw cutting → flush-out → cropping→ flattening testing → straightening → end chamfering → hydrostatic testing →ultrasonic testing for tube body → ultrasonic testing for tube ends → visual and dimensional inspection → weighing and measuring→ logo printing → coating Number → tube end protector → run-out table → packing → shipping
