Price spiral, spiral Tianjin, accessible VAI

Mastery of Tianjin Steel Trade Co., Ltd. specializes in the supply of various types of spiral pipe, pipe, seamless tube, reasonable price and stock. The gap is caused by the proximity effect is too small increases, excessive heat welding, burning resulting weld; welds or extruded to form a pit after rolling, it affects the quality of the weld surface. After the two edges of the tube is heated to welding temperature at squeezing rollers squeeze spiral 16mn, a common metal grains mutual penetration, crystal spiral theoretical formula, eventually forming a solid weld. 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, spiral 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, 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%, and lower production rate. Therefore, the smaller diameter pipe were powered by straight seam welded, large diameter spiral welded pipe for the most part.
