hf welded steel pipe mill line The production process of straight seam submerged arc welded pipe is flexible and can produce any specification and wall thickness within the production range, and the production efficiency is higher than that of high frequency straight seam welded steel pipe and spiral welded steel pipe.

　　The biggest advantage of the hf welded steel pipe mill line is that the straight seam submerged arc welded pipe can produce specifications and models that high-frequency steel pipes, spiral steel pipes, and even seamless steel pipes cannot be produced. The production cost of straight seam submerged arc welded pipe is higher than that of high-frequency steel pipe and spiral steel pipe, but there is a lot of room for price concessions compared with seamless steel pipe.

　　hf welded steel pipe mill line LSAW pipes can produce high-frequency steel pipes and materials that cannot be produced by spiral steel pipes, other high-frequency equipment and spiral equipment made of hard steel plates cannot be produced in China at present.

　　hf welded steel pipe mill line Longitudinal submerged arc welded pipe is widely used in domestic heavy steel structure engineering and fluid pipeline engineering, foundation piling engineering.
