The material at the bond line is anodic to the surrounding material and the result is a V-shaped groove with the apex of the V centered on the bond line.
Electric Resistance Welded (ERW) steel pipe is welded from a curled steel plate a curled steel strip. It is available in transportation of oil, natural gas, and chemical materials. It is also used as structure and mechanical square or rectangular pipe of a building in a city and even in the sea.

PHMSAFor ASME Section VIII-1, see UW-12(d)and UW-12(e) for your answer.1I'm having trouble following though. Another paragraph states it is not permissible to increase longitudinal eff. by supplemental RT.WAIT a Minute!!! If you X-ray your arm it does not get stronger. And If you X-ray (RT) a piece of (ERW) pipe it does not get stronger either. The ERW Longitudinal Weld Pipe 09Spot RT can mean 2 differnt things.

Apr 09, 2021Electric Resistance Welded (ERW) and High Frequency Induction (HFI) Welded Pipe. Originally this type of pipe, which contains a solid phase butt weld, was produced using resistance heating to make the longitudinal weld (ERW), but most pipe mills now use high frequency induction heating (HFI) for better control and consistency.Ultraic Production Monitoring of Small Diameter Weld and full-body inspections are undertaken simultaneously. The method, as well as compari with other techniques, will be described and analyzed. Keywords ultraic testing (UT), ERW pipes, ultraic production monitoring small diameter pipes. 1. Introduction Electro resistance welded (ERW) pipes are advantageous and becoming more common.What is ERW steel pipe - pipelinedubaiWhat is ERW steel pipe? ERW steel pipe is a straight seam electric resistance welded pipe, abbreviated as ERW pipe, which is a round pipe welded by steel plates. It is used to transport vapor and liquid objects such as oil and n atural gas, and can meet various requirements of high and low pressure. At present, it plays an important role in the world of transportation pipes.
Dec 09, 2014In response to the National Transportation Safety Board (NTSB) Recommendation P-09-1, the Department of Transportation (DOT) Pipeline and Hazardous Material Safety Administration (PHMSA) initiated a comprehensive study to identify actions that could be implemented by pipeline operators to eliminate longitudinal seam failures in electric resistance weld (ERW) pipe.
