LSAW (Longitudinal Submerged Arc Welding) steel pipe is a type of steel pipe produced using horizontal submerged arc welding process. This process is done in such a way that the pipe is opened in a cylindrical shape and then welding is done along its length. The features and advantages of LSAW steel pipes are: Production of large pipes: This process is suitable for producing pipes with large diameter and thickness. Continuous welding: The LSAW process continues in a continuous manner, and in this way, more welding is done without the need to weld at each individual point. High welding quality: The welds produced by this process are usually of high quality and conform to industry standards. Use in construction and oil and gas applications: LSAW pipes are commonly used in buildings, oil and gas projects, and industrial facilities. Resistance to internal pressure: Due to the continuous welding process and strong materials, these pipes have good resistance to internal pressure. Application in water and gas pipelines: As a convenient option, LSAW pipes are also used in water and gas pipelines. Overall, LSAW pipes are a popular choice due to their ability to produce large, high-quality pipes, fewer welding collisions, and use in industrial projects.
