General description:

Spiral welded pipe is made from strip in coil form. After the strip is uncoiled, it proceeds to a trimmer and then to forming rolls to shape it into spiral form. The spiral seam is submerged arc welded automatically and continuously V first on the bottom of the rotating pipe from inside, then on the top from outside. The welded pipe is cut to the top from outside. The welded pipe is cut to the specified lengths by a flying cutoff machine. X-ray and ultrasonic inspection ensure spiral welded pipe of consistently high quality.
