Material
Duplex 2205 (S31803/S32205)
OD Range
12.7 – 1219mm (1/2" – 48")
WT Range
1.0 – 20mm
Standard
ASTM A790 / A928
Overview
Our duplex 2205 welded pipes combine high strength with excellent corrosion resistance at a competitive price point for large-diameter applications. Every weld is subjected to post-weld solution annealing to restore the balanced austenite-ferrite microstructure, ensuring the weld zone matches the base metal corrosion resistance. Ideal for offshore water systems and desalination plants.
