LSAW steel pipes adopt the post-weld cold expansion process to expand the pipes, so the geometric dimensions of LSAW steel pipes are more accurate, and the matching quality when using LSAW steel pipes is good to ensure the quality of welding. Eliminate part of the internal stress. In addition, LSAW steel pipes are welded with multi-wire welding (three-wire, four-wire), and the heat input generated by this welding process is small, the degree of influence on the heat affected zone of the base metal is also small. After multi-wire welding, the welding wire of the first pass can eliminate the stress generated during welding, thereby improving the mechanical properties of the steel pipe. The base material can achieve 100% ultrasonic flaw detection of steel plates one by one to meet the requirements of high-pressure pipelines for base materials. However, although the overall performance of LSAW steel pipe is better than other steel pipes, its high price discourages users with tight funds.
