LSAW, SSAW, and ERW Pipes Description and

May 06, 2020 · In the oil and gas industry, large-diameter API 5L LSAW pipes are use d to transport hydrocarbons over long distances efficiently. HSAW (helical submerged arc welding) or SSAW pipe diameter range is generally 20 inch to 100 inch (406mm to 2540mm). One advantage of SSAW is the possibility to obtain different diameter. LSAW Welded Steel Pipe Features and Manufacturing ProcessHow to use LSAW welded steel pipe for pipelines. The basic metal and welding metal have been tested according to the specification of the pipe API SPEC 5L, DIN, EN, ASTM, GOST standard and other standards. Also, LSAW pipe can be welded with flanges, lifting eyes and other parts depending on clients requirements. SSAW Pipes, Spiral submerged-arc welding pipes,Spiral 42 rows · SSAW steel pipe is made up of hot-rolled coiled steel using a double-sided submerged arc SSAW Steel Pipe, Spiral Submerged Arc Pipe, SAWL Steel PipeThe spiral steel pipe feeds the strip steel into the welded pipe unit. After rolling by multiple rollers, the strip steel is gradually rolled up to form a round tube blank with an open gap. The reduction of the squeeze roller is adjusted to control the weld gap at 1~ 3mm, and make both ends of the welding joint flush. Machine of manufacturing SSAW steel pipe.
