SSAW steel pipe is a steel pipe made of strip coil plate, extruded at room temperature, and then welded by automatic double-wire submerged arc welding process. Before the steel pipe is formed, the strip steel will be levelled, trimmed, planed, surface cleaned, transported and bent to ensure its quality.
The weld gap control device is used to ensure that the weld gap meets the welding requirements, and the weld will be inspected by the online continuous ultrasonic automatic damage meter to ensure the non-destructive testing coverage of the spiral weld.
