What is LSAW steel pipe? Simply put, one of the welding processes of straight seam submerged arc welded pipe (LSAW for short) is submerged arc welding technology. The straight seam submerged arc welded pipe adopts filler welding and particle shielded flux submerged arc. The production diameter can reach 1500mm. When the diameter of the straight seam submerged arc welded pipe is greater than 914.4, the standard stipulates that the steel pipe is allowed to have two straight welds. The standards that can be implemented are GB/T3091-2008 low-pressure fluid steel pipe production standard, GB/T9711.1-2 -1997 petroleum and natural gas steel pipe production and use standard, and the American API 5L pipeline steel pipe implementation standard. Production materials: Q195A-Q345E; 245R; Q345QA-D; L245-L485; X42-X70. Widely used in steel structures, piling, fluid transportation, long-distance pipelines and other places.

The GB grade standards of LSAW straight seam submerged arc welded pipes include Q345A, Q345B, Q345C, Q345D, Q345E; there are also Q390A, Q390B, Q390C, Q390D, Q390E; Q420A, Q420B, Q420C, Q420D, Q420E; Q460C, Q460D, Q460E and other series of steel pipes.

Do you know about steel pipes? LSAW pipe (straight seam submerged arc welded pipe), also known as LSAW pipe. It uses Steel Plate as raw material, is formed by a forming machine, and then double-sided submerged arc welded. Through this process, the straight seam submerged arc Welded Steel Pipe will obtain excellent ductility, weld toughness, uniformity, plasticity and good sealing.

Diameter range and performance of LSAW steel pipe tube

LSAW pipe diameter range is larger than ERW, usually from 16 inches to 60 inches, 406 mm to 1500 mm. It has good resistance to high pressure and low temperature corrosion.

Application of SAWL steel pipe

Submerged arc welded steel pipe has been widely used in oil and gas pipelines, especially those that often require large diameter, thick wall, high strength, and long distance. And it is also often used in the construction of structures, water treatment, thermal engineering, bridge construction, etc. that require high strength. According to API specifications, SAWL pipe (SAWL pipe or JCOE pipe) is specifically designated for large-scale oil and gas transportation in the following situations: pipelines across cities, oceans, and urban areas.
