Welded Steel Pipe

In the form of welded steel pipe according to the weld seam welded pipe and SSAW steel pipe. Straight seam welded pipe production technology is simple, high production efficiency, low cost, rapid development. The strength of the spiral welded pipe is generally higher than straight seam welded pipe, use a narrow billet production of larger diameter welded pipe, you can also use the same width of billet in the production of different pipe diameter welded pipe. But compared with the same length of straight seam pipe, weld length by 30 ~ 100%, and the production speed is low. As a result, a small diameter welded pipe are mostly with straight seam welding, large diameter welded pipe for the most part adopts spiral welded. Low pressure fluid conveying in welded steel pipe is also called general welded pipe, commonly known as the clarinet. Is used to transport oil, gas, air, water and heating steam and other general low pressure fluid and other purposes of welded steel pipe. Steel tube wall thickness is divided into ordinary steel pipe and increasing pipe; To take over the side form is divided into without thread steel pipe (light pipe) and take rebar. Low pressure fluid conveying in welded steel pipe in addition to directly used for conveying fluid, also used as a low voltage large amounts of fluid conveying with galvanized welded steel pipe.
