Duplex Flanges Manufacturer in India

Sagar Steel Corporation is a Duplex Flanges Manufacturer. These flanges are a fusion of the strength of ferritic steel and the corrosion resistant characteristics of the austenitic grades with great performance in high corrosive and high-pressure conditions. Duplex flanges find application in the oil and gas industry, offshore, marine, chemical industries and pulp and paper industry. They have a high fatigue strength, crack resistance and dimensional stability due to their high technical structure in harsh conditions. The B2B portals in the present industrial supply chain have simplified the source of duplex flanges, proven and efficient to the buyers of all sectors. Such flanges are custom-made to satisfy specific needs like pressure ratings, dimensions and face types. They are ideal in bulk construction projects in harsh environments because of their assured longevity and immunity to stress corrosion cracking. When coupled with quick delivery and strong logistics, duplex flanges are an intelligent and long-term investment to industries focused on reliability, safety, and performance.

Frequently Asked Questions

What are the advantages of duplex flanges over standard stainless steel flanges?

Duplex flanges offer higher strength, better stress corrosion resistance, and improved fatigue resistance. They also provide excellent weldability and are ideal for use in high-chloride environments such as offshore platforms.

Can duplex flanges be customized for specific applications?

Absolutely. Duplex flanges can be tailored by pressure class, face type (RF, FF, RTJ), size, and material grade to meet unique project specifications. Custom machining ensures compatibility and optimal performance.

Are duplex flanges compatible with aggressive chemical environments?

Yes, duplex flanges perform exceptionally well in chemical processing plants, desalination units, and acidic environments due to their excellent resistance to pitting, crevice corrosion, and chloride-induced stress corrosion.
