LSAW Steel Pipe VS. SSAW Steel Pipe

The maximum length of the LSAW steel pipe is 15 m. If you want longer it should choose the T-Welded pipe. SSAW steel pipe can be produced in longer length (maximum length up to 50 meters) compared to LSAW steel pipes. Size Range and Performances Outside diameter of LSAW pipe ranging normally from 16 inches (406.4 mm) to 60 inches (1524.0 mm).LSAW Steel Pipe, DSAW Steel Pipe, Straight Seam Welded Welding Technology of LSAW Steel PipeLSAW steel pipe, hot-rolled or cold-rolled steel sheet or steel coil made of steel pipe welding equipment in the straight seam welding are called the straight seam welded pipe.

Longitudinal Submerged Arc Welding (LSAW) Processes Welding Technology of LSAW Steel Pipe

In LSAW pipe mills, processing is carried out by cold forming heavy carbon steel plates, the pipe prematerial on which many of the pipe properties depend. The material of LSAW steel pipe is unit middle or heavy thickness sheet, coiled in the molding or forming machine, welded by double submerged arc welding and expand the diameter.Longitudinal Submerged Arc Welding LSAW Steel Pipes Longitudinal submerged arc welding is a special welding technology used in pipe production. Because of high internal or external pressure, the final product needs high wall thickness. Considering this, the main applications of pipeline LSAW Steel Pipe s include oil, natural gas, natural gas, central heating, water supply, sewage treatment and Welding Technology of LSAW Steel PipeLongitudinally Submerged Arc Welded Steel pipes, LSAW Welding Technology of LSAW Steel PipeLSAW (Longitudinal double submerge arc welding) carbon steel pipe is a type of SAW pipe made of steel plates that were hot rolled by JCOE or UOE forming technology.

LSAW Pipe (Longitudinal Submerged Arc-Welding Pipe), also called SAWL pipe. It is taking the steel plate as raw material, mold it by the molding machine, then do double-sided submerged arc welding. Through this process the LSAW steel pipe will get excellent ductility, weld toughness, uniformity, plasticity and great sealing.SEAMLESS STEEL PIPE_ERW STEEL PIPE_LSAW STEEL PIPE Welding Technology of LSAW Steel PipeHunan Shinestar Steel Group(HSSG) was founded in 1978 and our enterprise is the predecessor of branch of China"s oil and gas pipeline science research institute, as the most authoritative pipeline engineering research institute, consists of eight backbone institute and line pipe bureau postdoctoral research stations, oil and gas pipe is "safe" the main body of the national engineering Welding Technology of LSAW Steel PipeSSAW Steel Pipe vs. LSAW Steel Pipe - ESC Global GroupMay 25, 2020Geometry accuracy of LSAW pipes is better than SSAW pipes, a key in the ease of installation. The welding line of LSAW pipe is around 60% lesser than of SSAW pipes. Using steel plates, quality of LSAW pipe can be tested by non-destructive procedures. While SSAW pipes using hot-rolled coils should be tested with destructive methods such as x-ray.
