API 5L Welded (ERW, LSAW, SSAW) Steel Line Pipe

For oil and gas storage, the best recommended type is ERW longitudinal, owing to its quality, ease of transport and cost. Both LSAW pipe and SSAW pipe are SAW pipe (Submerged Arc Welding Steel Pipe), is manufactured by making use of a submerged arc soldering process for preparing the steel and it results in high density pipe.API 5L Welded (ERW, LSAW, SSAW) Steel Line PipeThere are 3 welding types ERW (Electric Resistance Welding), LSAW (Longitudinally Submerged Arc Welding), and SSAW (Spirally Submerged Arc Welding) welding types. ERW pipe is a type of Resistance pipe stands apart from welded pipe and DC welded

Brief Description and Comparisons of LSAW, SSAW, and

LSAW Pipes has two types Longitudinal (Single or Double Straight-seam Weld, DSAW) and Spiral (also called SSAW, HSAW, or SAWL). What makes DSAW pipes differ from other LSAW pipes is that DSAW have a seam weld in the inside and outside of the pipe, while the latter have a single seam weld on the outer surface, longitudinal or cross sectional.Carbon Steel SAW, LSAW, HSAW Pipes and Tubes Longitudinal, Helical, Submerged Arc Welded Pipes, API 5L Carbon Steel LSAW Pipe Supplier, ASTM A672 Carbon Steel SAW Pipes, CS HSAW Pipes & Tubes, SAW Steel Pipe, API 5L Spiral Pipe, API 5L SAW Seamless Line Pipe, ASTM A671 Carbon Steel HSAW Pipes & Tubes Manufacturer in India.DSAW Pipes - JSW Steel LtdJSW Steel Works Texas is home to North America's premier high capacity straight seam longitudinal DSAW mill, employing the high speed, high capacity, U-O-E forming process.

The most popular process for large diameter pipe uses a longitudinal seam weld or Longitudinally Submerged Arc Welded Steel pipes (LSAW). DSAW Pipe is often produced by automatic double-wire double-sided submerged arc welding process.

SSAW Steel Pipe vs. LSAW Steel Pipe - ESC Group

The two main types of LSAW pipes are Longitudinal (single or double straight seam weld, DSAW) and Spiral (SSAW, HSAW, or SAWL pipe).

What is The Differences Between LSAW Pipe and SSAW 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.
