49 CFR § 192.113 - Longitudinal joint factor (E) for steel

Double submerged arc welded:1.00 ASTM A 671:Electric-fusion-welded:1.00 ASTM A 672:Electric-fusion-welded:1.00 ASTM A 691:Electric-fusion-welded:1.00 API Spec 5L:Seamless:1.00 Electric resistance welded:1.00 Electric flash welded:1.00 Submerged arc welded:1.00 Furnace butt welded.60 Other:Pipe over 4 inches (102 millimeters).80 Other DSAW pipe, Double Submerged arc welded pipe - Sunny SteelSpiral Welded steel pipe is distinguished by the manufacturing process that results in a spiral DSAW seam the length of the pipe to lengths of 155 feet. The manufacturing of Double Submerged Arc Welded Pipe involves first forming steel plates into cylindrical shapes.

Difference in ERW and SAWL - Guangdong Lizz Steel Pipe

Longitudinal submerged arc welding ( SAWL steel ) because it uses the welding cold expanding process pipe, so the SAWL pipe dimension precision, using SAWL steel pipe butt counterparts in good quality so as to ensure the welding quality, through expanding technology to some extent by removing a portion of the internal stress. Differences Between SAW and ERW Pipe Winsteel GroupSAW pipe means Submerged Arc Welded pipe. And from different weld seam, there are two saw pipes, including LSAW and SSAW. As the name suggests, SSAW has a spiral weld seam. And LSAW has a longitudinal weld seam. ERW pipe means Electric Resistance Welded pipe. Second Differences Between SAW and ERW Pipe We Will See It From The Weld Seam.

Mechanical properties of longitudinal submerged arc welded

Apr 01, 2008 · This is the reason why all the early steel pipes used for the submarine pipeline were imported. To research and develop steel pipes used for the submarine pipeline, the longitudinal-seam submerged arc welded (LSAW) pipes were made by using both the JCOE and UOE * Corresponding author.

ASTM A234 butt weld pipe LSAW pipes are also used in conveyance of flammable & nonflammable liquids, and as structural members in construction projects. LSAW pipe (longitudinal Submerged Arc Welding Pipe) is fromed by JCOE with one straight welded seam, the outer diameters usually from 323mm to 1420mm. Longitudinal Submerged Arc Welding (LSAW) Processes Application of LSAW Steel Pipe:The tubes are mainly used for oil, natural gas, gas, central heating, water supply, sewage treatment, low-pressure fluid delivery and so on.
