Description. STD Welded 304 Spiral Steel Pipe Product Description: Spiral welded pipe: It is made by rolling a low carbon carbon structural steel or a low alloy structural steel strip into a tube blank at a certain angle of a helix (called a forming angle), and then welding the pipe seam, which can be used in a narrower manner.

Q235B spiral steel pipe is a common materials in spiral tubes. It is a spiral seam steel pipe which It is based on strip coiled sheet and is extruded at room temperature, and welded by automatic double-wire double-sided submerged arc welding process. SSAW Welded Pipe GB/T9711 - galaxy-steel erw steel pipe q235b helical welding Strip surfacing weldingSpiral welded steel pipe is made of the raw material of steel strip coil, formed to round shape by roll molding, automatic double submerged arc welding process to weld the seam, then the pipe will be tested by UT, HT and other inspection to guarantee the quality. Standard: GB/T 9711 , SY/T 5037 , SY/T5040,API 5L . Steel Grade: SSAW steel pipe - COSASTEELSY/T5037-2000 also known as the common fluid pipeline with spiral seam submerged arc welded steel pipe. Advantages of SSAW steel pipe. When the strip steel is fed into the spiral pipe welding machine, it will automatically become a spiral and be welded continuously, and the welded steel pipe will almost become an accurate circle.
