Application of the welded steel pipe

Since the invention of welded steel pipes, more widely, welded steel pipes is included: double submerged arc welded pipe, high frequency steel pipe, spiral steel pipe, they each have their own characteristics in different areas to play a different role. Longitudinal Submerged arc welding is the use of such molding process JCOE or UOE steel plate having an opening into a tube then submerged arc welding, reliable product quality, can be used for oil and natural gas transmission, structural engineering. HF strip steel is molded into a tube having an opening, and then high-frequency welding, production weld I SAW pipe is much better than the higher, the product used for low-pressure fluid transfer and architectural decoration columns, etc.. Spiral steel pipe is the use of steel production, and its main feature is available with a specification of the strip can produce various caliber products, spiral weld quality lower than the submerged arc welded pipe, used for low-pressure fluid, decorative columns, etc..

In recent years as technology continues to evolve welded steel pipe production technology continues to improve, the quality is improving, such as seamless steel pipe out, it will get welded steel hot-rolled products, as compared with steel pipe prices high, so that in many fields instead of welded steel seamless application.
