In the welded pipe type we have another two sub types which you call EFW and ERW. ERW i.e Electric resistance welding ERW pipe and submerged arc welding pipe significantly dif electric fusion steel welded pipedifferentce between ERW pipe and EFW pipeLike low frequency ERW pipe, the seams of flash welded pipe are prone to rust and hook cracks, but to a lower level than ERW pipeline. R= Resistance and F= Fusion hence you would have Electric Resistance Welded Pipeline or Electric Combination Welded Pipeline. The more typical are 0.85 for ER W pipeline and 0.60 for CW pipe.
