Duplex S32205 Flanges Manufacturer & Supplier in India

Hi-Tech Engineering supplies Duplex S32205 Flanges for offshore, oil & gas, petrochemical, desalination, marine, and process industry applications. Duplex S32205 is a high-strength stainless steel grade offering excellent resistance to pitting corrosion, crevice corrosion, and chloride stress corrosion cracking.

Duplex S32205, commonly known as Duplex 2205, is supplied in accordance with UNS S32205, UNS S31803, and EN 1.4462 specifications. The material is widely selected for aggressive service conditions where conventional stainless steel grades may not provide adequate corrosion resistance.

Grade 2205 Duplex (UNS S32205) flanges provide approximately twice the yield strength of conventional 304 and 316 stainless steel grades while offering excellent resistance to chloride environments.

We supply Duplex S32205 forged flanges in Weld Neck, Blind, Slip On, Threaded, Socket Weld, and custom configurations manufactured in accordance with ASME B16.5 and ASME B16.47 standards. Flanges are available in Raised Face (RF), Flat Face (FF), and Ring Type Joint (RTJ) facings to suit different piping system requirements.

Duplex 2205 flanges are commonly used in offshore platforms, subsea systems, seawater handling equipment, desalination plants, fertilizer units, heat exchangers, pressure vessels, storage tanks, and chemical processing facilities. Their high resistance to chloride-bearing environments makes them a preferred choice for marine and coastal installations.

Compared with standard stainless steel grades such as 304 and 316, Duplex S32205 offers significantly higher yield strength along with improved resistance to stress corrosion cracking. These characteristics help reduce maintenance requirements and improve reliability in demanding industrial operations.

Hi-Tech Engineering can supply Duplex S32205 flanges in pressure ratings from Class 150 to Class 2500 with complete material traceability. Material Test Certificates (MTC), PMI testing, dimensional inspection reports, and third-party inspection documentation can be provided according to project specifications.

Our Duplex S32205 flange range is supplied to EPC contractors, fabrication companies, engineering consultants, refineries, power plants, offshore operators, and industrial maintenance projects across India and export markets including UAE, Saudi Arabia, Oman, Qatar, Kuwait, and Bahrain.

We also supply ASTM A105 Carbon Steel Flanges, ASTM A182 F316 Flanges, ASTM A182 F316L Flanges, ASTM A182 F347 Flanges, Super Duplex S32750 Flanges, Inconel 625 Flanges, Weld Neck Flanges, Blind Flanges, Slip On Flanges, and Threaded Flanges for industrial piping applications.
