2020-9-26  In 1970, the low frequency process was superseded by a high frequency ERW process which produced a higher quality weld. Over time, the welds of low frequency ERW pipe was found to be susceptible to selective seam corrosion, hook cracks, and inadequate bonding of the seams, so low frequency ERW is no longer used to manufacture pipe.

Difference between Seamless ERW Stainless Steel

2014-11-24  How to Identify Seamless or ERW Stainless Steel pipes? To identify that a pipe supplied is seamless or ERW, Simply read the stencil on the side of the pipe. If it is ASTM A53, Type S means seamless. Type F is furnace but welded, Type E is Electrical resist welded. Thats how. It is the easiest way to identify wether pipe is seamless or ERW.
