The characteristics of the high frequency welded pipe unit are: high welding speed, small welding heat affected zone, welding can not clean the workpiece, and can weld thin-walled pipes and weld metal pipes.
The production process of high-frequency welded pipe unit mainly depends on the product variety. From raw materials to finished products, a series of processes are required. The completion of these processes requires various mechanical equipment and welding, electrical control, and testing devices. These equipment and devices are in accordance with different The technological process requires a variety of reasonable arrangements, typical high-frequency welded pipe process: slitting —— uncoiling —— strip leveling —— head and tail shear —— strip butt welding —— looper storage —— forming —— welding —— Clear burrs —— Sizing —— Flaw detection —— Fly cutting —— Initial inspection —— Steel pipe straightening —— Pipe section processing —— Hydraulic test —— Flaw detection inspection —— Printing and coating —— finished products.
