Process flow of high frequency welded pipe units
High-frequency welded pipe unit is characterized by: welding speed, welding heat-affected zone is small, welding on the workpiece can not be cleaned, can be welded thin-walled pipe, can be welded metal pipe.
High-frequency welded pipe production process mainly depends 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 machinery and equipment and welding, electrical control, testing devices, these devices and equipment in accordance with the requirements of different processes have a variety of reasonable layout, high-frequency welded pipe typical process:
longitudinal shear - uncoiling -Strip leveling - head and tail shear - strip butt welding - live sleeve storage - forming - welding - burr removal - sizing -Flaw detection - flying cut - initial inspection - pipe straightening - pipe section processing - hydraulic test - flaw detection - printing and Coating - Finished product.
