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
