Difference between the High Frequency Straight Seam Welded Pipe and the Spiral Welded Pipe Business Articles | March 2 Adidas NMD Chukka Danmark , 2017
The main difference between the high frequency straight seam welded pipe and the spiral welded pipe is that the first production process is that the first straight seam welded pipe is formed by first forming the hot rolled coil into a cylindrical shape having a smooth outer surface and then proceeding welding.?
Welding is the use of proximity or flux under the burning of the arc and skin effect, heating the edge of the tube and to melt, in the appropriate extrusion under the cooling molding. Longitudinal submerged arc welded pipe and high frequency straight seam welded pipe is different from the edge of the tube melting method, the general use of arc melting is called straight seam submerged arc welded pipe Adidas NMD R2 Danmark , and high-frequency straight seam welded pipe is the use of high-frequency current melting. Spiral welded pipe production process is in accordance with the appropriate helix angle of low-alloy structural steel and low-carbon carbon steel rolled into a tube, and then welded pipe forming. Spiral submerged arc welded pipe is the main form of spiral welded pipe. It is the most significant feature of spiral steel pipe?which can produce large diameter steel pipe with narrow billet. It is widely used in the construction of gas pipeline in all walks of life. x China[/url]
