Classification of welded steel pipe
According to weld shape, welded steel pipe can be divided into LSAW steel pipe and spiral welded pipe. Among them, the straight welded pipe: the production process is simple, high efficiency, low cost, rapid development. Spiral welded pipe: Longitudinal strength is generally higher than that, can narrow the billet production of large diameter pipe, you can also use the same width of the billet production of different pipe diameters. However, with the same length of straight pipe seam, compared weld length of 30 to 100%, and lower production rate. Therefore, most of the use of smaller diameter straight seam welding pipe, large diameter spiral welded pipe are mostly used.

By the application,welded steel pipe can be divided into general-use pipe, galvanized pipe, oxygen pipe, wire pipe, metric pipe, roller pipe, deep well pump tube, automotive tube, transformer tube, welding thin-walled tube , welding shaped tube and spiral welded steel pipe.
