High Quality Spiral Pipe Making Welding Machine Spiral welded pipe is an important kind of steel pipe, which is widely used in water, oil, natural gas and other fluid transportation, structure, pile driving and other engineering fields. As spiral steel pipe can be continuously produced from one width steel pipe, it is easy to realize production automation, and automatic double-sided submerged arc welding is used. In the production process, ultrasonic flaw detection, X-ray flaw detection, hydraulic pressure test and other detection methods can be used to effectively control its quality, so spiral welded pipe has been widely used. The spiral steel pipe machine is used to manufacture spiral seam welded pipes. It can produce steel pipes of different diameters with strips of the same width, and steel pipes of the same diameter with strips of different widths.…
