The process of high-frequency welded pipe production 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 mechanical equipment and welding, electrical control, detection devices, these devices and devices in accordance with different processes with a variety of reasonable layout of the process, high-frequency welded pipe typical process: open book – strip leveling – head and tail shear – steel butt welding – live storage – forming – welding – remove the burr – sizing – initial inspection – straightening of pipe – pipe section processing – water pressure test – flaw detection – printing and coating – finished product.
High-frequency welding is the use of continuous contact with the workpiece surface of the high-frequency current generated by the heat generated by heating and in the case of the application of forging force, the workpiece metal to achieve a series of welding methods. It is similar to ordinary resistance welding, but there are many important differences.High-frequency welding for carbon steel pipe production has been 40 years of history. High-frequency welding has a large power supply, the different materials, caliber and wall thickness of the steel pipe can achieve a higher welding speed (higher than the maximum welding speed of welding more than l0 times). Therefore, the high-frequency welding production of general-purpose steel pipe has a high productivity because of high-frequency welding speed, to the pipe to remove the burrs difficult, which is the current high-frequency welded steel pipe is not acceptable for the chemical industry, nuclear industry one. From the welding material, high-frequency welding can be welded all types of steel pipe.
Important part of high frequency welded pipe production process
1. In the process of high-frequency welded pipe production, how to ensure that product quality in line with the requirements of technical standards and customer needs
