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): 12–203 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 preventing harmful intermetallic phase (σ phase) precipitation in harsh marine and chemical corrosion environments)
- Application Scope: Suitable for pipelines transporting liquids and gases. Widely used in boiler systems, chemical processing, offshore platforms, marine piping systems, and other industrial fields requiring high strength and superior corrosion resistance.
