Duplex Flanges Manufacturer in India widely used in oil gas offshore chemical processing and industrial pipeline applications

Sagar Steel Corporation is a trusted Duplex Flanges Supplier in India, which provides high-strength and corrosive resistant flanges to be used in the challenging piping and pressure-system jobs in industries. Duplex flanges are produced out of duplex stainless steel alloys which entail a combination of both austenitic and ferritic microstructures, which gives superior mechanical strength, high resistance to stress corrosion cracking and high reliability in the operation amidst aggressive service environments. They find extensive application in oil and gas, offshore, chemical processing, marine, desalination, power generation, and heavy engineering industry.

Being a reputable supplier in a global B2B portal, we guarantee that all duplex flanges are in accordance with any of the recognized international requirements i.e. ASTM, ASME, ANSI, DIN, and EN. It manufactures our flanges in different sizes, pressure ratings, and types of facing to enable purposes of making a safe and leak-free contact in high-pressure and high-temperature piping systems. High standards of quality control, checking of dimensions, and testing of materials guarantee uniform performance, extended service life, and compliance of the project.

Duplex Flanges – Material & Grade Table

Material	Grade / Specification	UNS No.	Key Properties	Applicable Standards
Duplex Stainless Steel	Duplex 2205	S32205 / S31803	High strength, excellent corrosion resistance	ASTM A182 / ASME B16.5
Duplex Stainless Steel	Super Duplex 2507	S32750	Superior pitting & crevice corrosion resistance	ASTM A182 / ASME B16.5
Duplex Stainless Steel	Duplex 2304	S32304	Good corrosion resistance, cost-effective	ASTM A182
Duplex Stainless Steel	Super Duplex Zeron 100	S32760	High PREN, offshore-grade corrosion resistance	ASTM A182
Duplex Stainless Steel	Duplex Alloy	—	Balanced austenitic–ferritic structure	ASTM / EN Standards

Duplex flanges have wide applications in pipelines, pressure vessels, heat exchangers, pumps, valves, and offshore structural systems where there is need of high mechanical strength as well as corrosion resistance. Their high resistance to corrosion, pitting and crevice attack caused by chloride, makes them to be especially applicable in sea water, acidic and saline environment. We also offer a designed duplex flanges depending on drawings and technical specifications to match the special engineering requirements.

Key Features of Duplex Flanges

Duplex flanges are chosen in the industry of critical applications because of the great resistance to corrosion, high strength and durability.

Great mechanical strength in opposition to conventional stainless steel flanges.
Good pitting, crevice and stress corrosion resistance.
Proper to work in high pressure and high temperature.
Excellent weldability and fabrication.
High service life at harsh and offshore conditions.

The above properties render duplex flanges to be a reliable answer to challenging piping and structural systems.

We also offer a full selection of Stainless Steel Flanges, Alloy Steel Flanges and Super Duplex Flanges in addition to duplex flanges to meet the needs of multi-material projects. This wide product range allows customers to obtain matching flange requirements concerning standard, high pressure, and stressful applications under one industrial supplier.
