Duplex Stainless Steel (DSS) and Super Duplex Stainless Steel (SDSS) welded pipes are manufactured via cold working processes with automatic welding. Key specifications and details are as follows:
- Outer Diameter (OD): 12–1219.2 mm
- Wall Thickness: 1.24–30.96 mm
- Surface Treatment: Acid-washed (removes oxide scale, weld residues, and surface contaminants, enhancing corrosion resistance and surface cleanliness—critical for harsh service environments such as offshore and chemical corrosion)
- Application Scope: Suitable for pipelines transporting liquids, gases, and particulate media. Widely used in boiler systems, chemical processing, offshore platforms, marine piping systems, and other industrial fields requiring high strength and corrosion resistance.
