Description

Duplex 2205 Stainless Steel Seamless Pipe ASME SA790 for Chemical Processing Oil

1. Product Description

Duplex stainless steel pipe is a two-phase (austenite + ferrite) tubular product offering an optimal combination of high strength and corrosion resistance. It is produced in seamless and welded forms per ASTM A789/A790, with standard grades including 2205 (S32205), 2507 (S32750), and 2304 (S32304). The material is delivered in solution-annealed and pickled condition, with full traceability and mill test certification.

2. Product Applications

Sector Typical Services
Offshore Oil & Gas Subsea flowlines, topside piping, manifolds
Chemical Processing Organic acids, chloride-bearing media, heat exchangers
Marine Engineering Seawater systems, desalination, FPSO piping
Energy Geothermal, FGD systems, hydrogen transmission
Pulp & Paper Bleaching lines, digesters

​3. Product Advantages

  • Yield strength approx. 2× that of 316L (450 MPa vs. 170 MPa for 2205)

  • PREN 35–42+ provides superior pitting/crevice resistance

  • Outstanding resistance to chloride SCC up to ~250°C

  • Weight savings 30%+ vs. austenitic grades through reduced wall thickness

  • Lower Ni content provides cost stability and nickel-price independence

  • Good weldability without PWHT for thickness ≤ 20mm
