Tubería de acero de China: expansión del diámetro de la tubería de acero LSAW-tubería de acero lsaw
La tubería de acero LSAW es una tubería soldada producida presionando (laminando) la placa de acero en un tubo en bruto en un molde o una máquina formadora, y utilizando un método de soldadura por arco sumergido de doble cara y expandiendo el diámetro. El producto terminado tiene una amplia gama de especificaciones, buena tenacidad, plasticidad, uniformidad y compacidad de la soldadura, y tiene las ventajas de un gran diámetro de tubería, espesor de pared de la tubería, resistencia a alta presión, resistencia a bajas temperaturas y fuerte resistencia a la corrosión. Tubería de acero LSAW La expansión es un proceso de procesamiento de presión que utiliza medios hidráulicos o mecánicos para aplicar fuerza desde la pared interior de la tubería de acero para expandir la tubería de acero radialmente hacia afuera. El método mecánico es más simple y eficiente que el método hidráulico, y el mecanizado de tubos de acero es más preciso bajo condiciones de alta precisión. El proceso de expansión de los tubos de acero LSAW se divide en expansión mecánica y expansión hidráulica.Leer más -
China Steel Pipe-Differences Between ERW and LSAW Steel Pipe-lsaw steel pipe
Straight seam welded steel pipes are divided into high frequency resistance welding and submerged arc welding according to the welding process. Straight seam submerged arc welding is referred to as LSAW, and longitudinal high frequency resistance welding is referred to as ERW.Compared with submerged arc welding, high frequency electric resistance welded steel pipes (ERW steel pipes) do not add any welding materials during the welding process in the ERW process, and the weld formation does not undergo a thermal melting state, but the weld metal undergoes a recrystallization process. Therefore, the formed weld seam is completely consistent with the chemical composition of the base metal. After the steel pipe is welded, it is annealed to produce the cold working internal stress and welding internal stress. Therefore, the comprehensive mechanical properties of the ERW steel pipe are better.Leer más -
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.Leer más -
