Which is better LSAW or ERW steel pipe?
Through this process the LSAW steel pipe will get excellent ductility, weld toughness, uniformity, plasticity and great sealing. The LSAW pipe diameter range is larger than ERW, normally from 16 inch to 60 inch, 406mm to 1500mm. Good performances on high pressure resistance, and low-temperature corrosion resistance. Octal has LSAW pipe on sale.See all results for this questionWhat's the difference between a dsaw and a LSAW pipe?Therefore, the difference between DSAW vs. LSAW is that DSAW pipes have a seam weld in the inside and outside of the pipe, whereas LSAW pipes have a single seam weld on the outer surface. The difference between LSAW and ERW pipes is that LSAW pipes are produced using steel plates, ERW pipes are manufactured starting from steel coils.See all results for this questionWhat's the difference between SSAW and strip steel pipes?The strip steel with the same specification can produce SSAW pipes with various diameters. The welding joints can avoid major stress and have better force resistance. Disadvantages are poor geometrical diameters; longer welding joints and joints are easily to have cracks, porosity and other welding defects.See all results for this question
What kind of welding is used in LSAW pipe?
LSAW Pipe (Longitudinal Submerged Arc-Welding Pipe), 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.See all results for this questionWhat is The Differences Between LSAW Pipe and SSAW PipeIt 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.
