The production process of high-frequency welded pipe mainly depends on the variety of products. A series of processes are required from raw materials to finished products. The completion of these processes requires various mechanical equipment and welding, electrical control and detection devices. These equipment and devices are reasonably arranged according to different process requirements, Typical process of high-frequency welded pipe: uncoiling - strip leveling - head and tail shearing - strip butt welding - looper storage - forming - Welding - burr removal - sizing - flaw detection - fly cutting - initial inspection - steel pipe straightening - pipe section processing - hydrostatic test - flaw detection - printing and coating - finished products.
