Double Submerged Arc Welded (DSAW) steel pipe is available in straight and spiral welded formats and used in a variety of applications. The submerged welding process protects the steel from contamination of impurities in the air.
DSAW pipe is made of steel plate as raw material, and is often extruded by automatic double-wire double-sided submerged arc welding process. DSAW pipe is simple, high efficiency and low cost. In the steel pipe forming steel plate deformation evenly, the residual stress is small, does not appear to scratch the surface of the phenomenon.
In the diameter and thickness of the steel pipe size specifications can be used flexibly in the production of large diameter thick seam steel pipe advantage is more obvious.
In the production process can be pre-welded after welding inside and outside, to ensure that welding does not appear wrong side, welding bias and not penetration and other defects, the quality of welding control easier.
Application:
It is mainly used for conveying medium such as onshore and offshore oil and gas, coal slurry and mineral slurry, as well as pipe for offshore platform, power station, chemical industry and urban building structure.
