Dec 19, 2018 · Outside weld is the tandem multi-wire submerged arc welding on the outer part of the LSAW steel pipe welding. 8. Ultrasonic Testing. This test is checking outside and inside a straight seam of welded LSAW steel pipe. And also check both sides of the base material. 100% of pipes are taking ultrasonic inspection. 9. X-ray inspection. Difference in ERW and SAWL - Alloy Pipe, Tubes, Ceramic Difference in ERW and SAWL. Straight seam welded steel pipe, according to welding process can be divided into high frequency resistance welding and submerged arc welding, longitudinal submerged arc welded is short for SAWL, high-frequency straight seam resistance welding
Dec 19, 2018 · LSAW pipe weld seam. And the weld seam of the SAW pipe is not flat. You will see the weld seam of the LSAW pipe and SSAW pipe is higher than the steel plate. And the tolerance of weld seam height specified in specifications. If compare ERW pipes with SAW pipes, ERW pipes surface quality is better. ERW pipes are smooth and have a better finish. Global Longitudinal Submerged Arc Welded Pipe (LSAW) The global Longitudinal Submerged Arc Welded Pipe (LSAW) market is segmented by company, region (country), by Type, and by Application. Players, stakeholders, and other participants in the global Longitudinal Submerged Arc Welded Pipe (LSAW) market will be able to gain the upper hand as they use the report as a powerful resource.
lSAW ( Welded Pipes )Manufacturing Process. UOE is a method used for production of longitudinally welded large diameter pipes. Longitudinal edges of steel plates are first beveled using carbide milling equipment. Beveled plates are then formed into a U shape using a U-press and subsequently into an O shape using an O-press. LSAW Steel PipeProduct Advantages of LSAW Steel Pipe (1) Without the unwind process, the base material indentation, scratch less. (2) The wrong side, slotted, and other easy-to-diameter perimeter control, excellent welding quality.

The difference is SSAW pipes are welded in the helix or spiral position while LSAW pipes are welded in the longitudinal direction. Manufacturing process of SSAW pipe is by rolling and welding a steel strip in a way that the pivotal direction is oblique to the axis or pipe center, making the weld seam in a spiral line.

Spiral submerged arc welding (SSAW) steel pipe,also called HSAW pipe,welding line shape like a helix.It is using the same welding technology of Submerged Arc-Welding with LSAW pipe.Differently SSAW pipe is spiral welded where the LSAW is longitudinally welded.Manufacturing process is rolling the steel strip,to make the rolling direction have an angle with the direction of the pipe center,forming and welding, so the welding seam is in a spiral line.The SSAW pipe Types of Oil & Gas Pipes:Seamless, ERW, LSAW Dec 20, 2018 · An LSAW pipe (submerged arc welding) is manufactured by cutting, bending, and welding steel plates (JCOE process). LSAW pipes compete with seamless and ERW pipes in the size range between 16 and 24 inches but are must-go options for pipelines above 24 inches (as 24 inches is the maximum size for commercial seamless pipes).
Longitudinally Submerged Arc Welded Steel pipes . LSAW (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 (Longitudinally Submerged Arc Welded Steel pipes) in leaflets plate as raw material, the steel plate in the mold or molding
