ERW Pipe Manufacturing Process - Permanent SteelHigh-frequency straight seam resistance welded steel pipe, abbreviated as ERW, is a hot-rolled coil that is formed by a forming machine, and uses the skin effect and proximity effect of high-frequency current to heat and melt the edge of the tube blank, and press it under the action of a squeeze roller Welding to achieve production. ERW Steel Pipe-ASTM A252 Spiral Steel Pipe_ASTM A106 GR Specification. ERW Steel Pipe. Electric Resistance Welded Steel Pipe. Usage:Used for low pressure liquid delivery, such as water, gas, and oil.Oil drilling and machinery manufacturing, etc. Process:ERW :Electric Resistance Welded pipe HFI:High Frequency Induction weld pipe EFW:Electric Fusion Welded Pipe Standard:API 5L, API 5CT, ASTM 53, EN10217, DIN 2458.
ERW welding can be applied when manipulating both high and low strength materials. Welding tube using the electric resistance method creates a very uniform, straight end product with one continuous weld. Hence no re-straightening is required. High- frequency electrically welded tubes can be produced at high speeds.

Electric Resistance Welded (ERW) Pipe Manufacturing Oct 19, 2020 · In 1970, the low frequency process was replaced by the high frequency ERW pipe process, which produced higher quality welds. Over time, it has been found that the welds of low-frequency ERW pipes are susceptible to selective joint corrosion, hook cracks and insufficient joint bonding. Therefore, low-frequency ERW is no longer used to make pipes.
Initially this manufacturing process used low frequency A.C. current to heat the edges. This low frequency process was used from the 1920s until 1970. In 1970, the low frequency process was superseded by a high frequency ERW process which produced a higher quality weld.
