Super duplex fittings are engineered from high-performance duplex stainless steel, combining superior corrosion resistance, strength, and reliability. They are ideal for challenging environments such as offshore, chemical processing, and desalination systems.

These fittings are designed to offer both the mechanical toughness of austenitic steels and the corrosion resistance of ferritic steels—delivering exceptional performance under chloride exposure, high pressures, and temperature fluctuations.

Key Features & Applications

Highlights of super duplex fittings include:

• Excellent resistance to pitting, crevice corrosion, and stress corrosion cracking in chloride environments
• High strength, enabling lighter, thinner sections without compromising solidity
• Available in a wide variety of fittings—elbows, tees, reducers, couplings, and more
• Precision fabrication and finishing to ensure dimensional accuracy and leak-proof joints
• Rigorous testing, including hydrostatic, dimensional, and material verification against ASTM, ISO standards

These fittings are well suited for aggressive media handling, seawater systems, oil & gas, petrochemical, and pulp & paper processes, where durability and corrosion resistance are paramount.

Each fitting is inspected at multiple production stages to verify chemical composition, mechanical properties, and sealing integrity, ensuring consistent quality and reliability.

Proper installation, suitable gaskets, torque control, and periodic inspection help optimize performance and extend service life in demanding environments.

With advanced metallurgy and precise manufacturing, super duplex fittings deliver robust performance, low maintenance, and long service life in harsh operational conditions.
