Product Overview

Our duplex and super duplex stainless steel pipes and fittings are manufactured to ISO 1127, ASTM A815 (for pipes), and ASTM A403 (for fittings), ensuring superior performance in corrosive and high-pressure environments. These products are ideal for oil & gas, chemical processing, desalination, and offshore applications, offering excellent strength, corrosion resistance, and cost efficiency compared to standard stainless steels.

Available in UNS S31803 (2205), S32205, S32750 (Super Duplex), and S32760 (Zeron 100), our pipes and fittings come in Schedule 10 to Schedule 100 (SCH10-SCH100) for various pressure requirements.

 

Key Features & Benefits

 High Corrosion Resistance - Exceptional resistance to chlorides, acids, and pitting/crevice corrosion, ideal for seawater and chemical exposure.
 Superior Strength - 2x the yield strength of 304/316 stainless steel, allowing thinner, lighter, and more cost-effective designs.
 Pressure-Rated - Suitable for high-pressure piping systems (up to 10,000 PSI, depending on schedule).
 Seamless & Welded Options - Available in seamless (for high integrity) and welded (for cost efficiency).
 Full Range of Fittings - Elbows (90° & 45°), tees, reducers, caps, and stub ends in matching duplex grades.
 Global Certifications - Compliant with ISO, ASTM, ASME, PED, and NACE MR0175 for sour service.
