High Frequency Induction (HFI) Welded Pipe Steel blog

In High Frequency Induction (HFI) Welded Pipe production process, hot rolled steel coils are fed with a high capacity accumulator in order to achieve continuous welding. HIGH FREQUENCY WELDING is a welding process in which the heat source used to melt the joining surfaces is obtained from high frequency (HF) alternating current (ac) resistance heating.

Production process of high frequency welded pipe

The high frequency welding of carbon steel pipe has a history of 40 years. High frequency welding has a large power supply, and the different materials, caliber and wall thickness of the steel pipe can reach high welding speed (higher than l0 times the maximum welding speed). Therefore, the high frequency welding production of universal steel tube has high productivity because of high frequency and high welding
