Mastery of Tianjin Steel Trade Co., Ltd. specializes in the supply of various types of spiral pipe, pipe, seamless tube, reasonable price and stock. Spiral characteristics: Longitudinal production process is simple, high efficiency, low cost, rapid development. The strength of the spiral welded pipe is generally higher than the Longitudinal, can narrow the billet production of large diameter pipe, spiral price, you can also use the same width of the billet production of different pipe diameters. However, compared with the same length of straight pipe joints, weld length of 30 to 100%, Hebei spiral, and lower production rate. Therefore, the smaller diameter pipe were powered by straight seam welded, large diameter spiral welded pipe for the most part. Mastery of Tianjin Steel Trade Co., Ltd. specializes in the supply of various types of spiral pipe, pipe, seamless tube, reasonable price and stock. Using air plasma cutting machine will cut a single tube. Cut into a single pipe, each batch of steel pipe should be carried out strict inspection system, the mechanical properties of the weld inspection, chemical composition, fusion status, quality steel surface and after NDT inspection, spiral pipe, pipe technology to ensure that qualified before we can formally put into production.
