In our engineering solutions firm, we deliver piping components engineered for the most rigorous industrial demands. Super duplex flanges stand as a landmark of metallurgical design, providing extraordinary resilience in service conditions that compromise lesser materials.

What Constitutes a Super Duplex Flange?

Super duplex flanges are high-performance piping elements produced from a proprietary stainless steel formulation that merges elevated strength with superior resistance to corrosion.

In contrast to conventional stainless flanges, these components exhibit a defined microstructure of nearly equal proportions, approximately 50% austenite and 50% ferrite, thereby yielding exceptional mechanical integrity, resistance to pitting and stress corrosion cracking, and long-term durability.


Key Characteristics of Super Duplex Flanges

1. Exceptional Corrosion Resistance

• Outstanding resistance to pitting and crevice corrosion.
• Particularly suited for marine, chemical, and off
