What is the difference between SSAW ,LSAW and ERW steel pipes ?

SSAW (Spiral Submerged Arc Welding), LSAW (Longitudinally Submerged Arc Welding), and ERW (Electric Resistance Welded) are all methods of producing steel pipes. They each have their own distinct characteristics, advantages, and disadvantages: SSAW (Spiral Submerged Arc Welding) Steel Pipes: The SSAW pipe is produced by spiral submerged arc welding. This […]
