LSAW Pipes and Their Applications-lsaw steel pipe-Welded Steel Pipe
The manufacturing process of Longitudinal Submerged Arc Welded (LSAW) pipes is a complex and precise procedure designed to produce durable and reliable steel pipes for diverse industrial applications. The process typically begins with the uncoiling of a steel coil, which is then leveled and trimmed to the required size. The prepared steel strip is then formed into a cylindrical shape through a series of bending operations. Subsequently, longitudinal welding is carried out using the submerged arc welding method. This involves creating a high-quality weld seam along the length of the pipe by melting the edges of the steel plate with a continuous electrical arc, while a granular flux shields the welding area, ensuring a clean and efficient weld.In the case of UOE (Uing and Oing) LSAW pipes, after the initial welding, the pipe undergoes Uing, Oing, and expanding processes to achieve the desired dimensions and mechanical properties. Similarly, the JCOE (J-ing, C-ing, O-ing, and E-ing) LSAW pipes involve multiple steps, including J-ing and C-ing to form the initial shape, O-ing for further shaping, and E-ing for final expansion. These processes contribute to the overall strength and integrity of the LSAW pipes, ensuring they meet stringent quality standards. The final steps of the manufacturing process include inspection, testing, and coating to guarantee the pipes' performance and longevity in various industrial environments.
