  What are sizes of SSAW steel pipes?

  Spiral Submerged Arc Welded (SSAW) steel pipes are widely used in oil & gas, water transmission, and structural engineering projects due to their ability to support large diameters and medium-to-thick wall designs. Pipe size is typically defined by outside diameter (OD) and wall thickness, making it flexible for different pressure and flow requirements.

  Why is 316L stainless steel pipe resistant to chloride ion corrosion?

  316L Stainless Steel Pipe resists chloride ion corrosion mainly because it contains molybdenum (Mo) and low carbon content, which improve the stability of the passive oxide film on the steel surface. This protective film helps reduce oxidation, pitting corrosion, and stress corrosion cracking in many industrial environments.
