Product details

Duplex Steel Flanges are hardened alloys and also exceptionally corrosion-resistant. Microstructures of this steel are consist of Ferrite and Austenite phases mixture. As a result, they consist of the features of both ferritic and austenitic stainless Steel. It has a high-strength and excellent resistance to corrosion. Duplex Stainless Steel Flangeshave excellent intergranular corrosion. It has an outstanding high resistance to corrosion cracking stress even in sulfide and chloride environments.

At the temperatures, more than 300 degree Celsius Duplex Steel Flanges is still protected from the corrosion causes embrittlement. Duct ability is excellent in low temperatures also. The fabrication work is done only through the tools assigned for materials of stainless steel. Before they used must be cleaned properly. It is done to save the stainless steel from the cross-contamination from the corroded metals.

These flanges can be hardened by the treatment of heat. Duplex Steel Flanges are application industries are; They are used in off-shore oil drilling companies, used in Aircraft exhaust manifolds, uses in petrochemicals, in power generation, in gas processing, in pharmaceuticals, uses in specialty chemicals, spiral welded tube for burner pipes and fuels, pharmaceutical equipment, heat exchangers, and also in seawater equipment. Double Steel Flanges are available in the many designs like slip-on, weld-neck, blind, threaded, lap joint, and socket weld.

The test certificate is according to the EN 10204/31B. Material testing includes intergranular corrosion (IGC) test, flaring test, pitting resistance test, micro, and macro test, flattening test, positive material identification test, chemical analysis, hardness test, and mechanical testing such as tensile of area. The packaging is in wooden pallets and cases to avoid the damages of the material during its delivery and to maintain the trust of the customers.
