1. Spiral submerged arc welded steel pipe (SSAW) and longitudinal submerged arc welded steel pipe (LSAW) In the 1950s and 1960s, spiral steel pipes were widely used in oil and gas pipelines. In the 1970s and 1980s, they were severely challenged by longitudinal submerged arc welded steel pipes (LSAW steel pipe) and ERW steel pipes. So far, spiral steel…
Read MorePerformance comparison of carbon ERW steel pipe and spiral steel pipe: 1. Overview The welding of ERW steel pipe is the skin effect and proximity effect of high-frequency current. The process of using high-frequency current and induced high-frequency current (rising at the end of the 20th century) resistance to heat and melt the edge of the tube blank, and…
