^{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.}
