Product Overview

Our Duplex 2205 Stainless Steel Pipes (UNS S32205) are premium-grade corrosion-resistant pipes designed for extreme service conditions in aggressive environments. Manufactured to ASTM A928 standards with NACE MR0175 compliance, these pipes combine exceptional strength with outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking (SCC).

Ideal for oil & gas, chemical processing, offshore, and desalination applications, these pipes offer twice the yield strength of standard 300-series stainless steels, enabling lighter and more cost-effective designs.

 

Key Features & Benefits

 Superior Material:

• Grade: Duplex 2205 (UNS S32205 / F51/F60)

• PREN ≥ 35 (Pitting Resistance Equivalent Number) for chloride-rich environments.

• 50-50 Austenite-Ferrite microstructure for optimal strength and corrosion resistance.

 Precision Manufacturing:

• Seamless & Welded options (EFW/LW) available.

• Sizes: ½″ to 24″ OD (DN15 to DN600) | Wall Thickness: SCH10S, SCH40S, SCH80S, XXS (customizable).

• Surface Finish: Pickled, polished, or as required.

 Certified Performance:

• Compliant with ASTM A928 (ferritic-austenitic pipes), ASME SA790, and NACE MR0175/ISO 15156 for sour service (HS environments).

• Third-party tested (PMI, hydrostatic, UT/RT available).
