Process flow of high-frequency welded pipe unit
High-frequency welded pipe unit is characterized by: welding speed, welding heat-affected zone is small, welding on the workpiece can not be cleaned up, can be welded thin-walled pipe, can be welded metal pipe.
High-frequency welded pipe unit production process depends mainly on the product variety, from raw materials to finished products need to go through a series of processes, the completion of these processes require a variety of mechanical equipment and welding, electrical control, testing devices, these equipment and devices in accordance with the requirements of different processes have a variety of reasonable arrangement, high-frequency welded pipe typical process: longitudinal shear - uncoiling -Strip leveling - head and tail shear - strip butt welding - live sleeve material storage - molding - welding - burr removal - sizing -Flaw detection - Fly cutting - Initial inspection - Pipe straightening - Pipe section processing - Hydrostatic test - Flaw detection - Printing and Coating - Finished products.
