Welded Steel Pipe

Welded steel pipe refers to welded steel strip or plate by means of bent round, square and other shapes and then welded into the surface of the steel pipe seam.
Welded steel blanks is used in steel sheet or strip, according to the different welding processes, it can be divided into the furnace pipe, welded (ERW) pipes and automatic arc welded pipe. Because of the different forms of welded pipe, which is divided into two and spiral welded pipe. Its shape is divided into round ends welded and shaped (square, flat, etc.) pipe.
Welded pipe, welded steel common market in general are: double submerged arc welded pipe(DSAW), high-frequency welded pipe (ERW), spiral submerged arc welded pipe(SSAW). Double submerged arc welded pipe is made using the molding machine has a tube opening, re-use double-sided submerged arc welding. Pipe is the use of high-frequency skin effect of high frequency current production of steel. The use of a narrow spiral submerged arc welded pipe is made of steel pipe-shaped roll, and use submerged arc welding, spiral weld, the weld compared Longitudinal length, compared with Longitudinal, it can use a specification made with a variety of large-diameter steel pipe.
Longitudinal spiral steel strength is generally higher than that, which 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 seam pipe, weld length of 30 to 100%, and lower production rate. Therefore, smaller diameter pipe is mostly a straight seam welded, large diameter spiral welded pipe is mostly used.
