Electric Resistance Welded (ERW) Pipe Manufacturing ProcessIn 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.
