Unmatched Corrosion Resistance for Demanding Environments

DUPLEX 2205 flanges feature excellent corrosion resistance, making them suitable for harsh applications including chemical plants, oil & gas pipelines, and marine environments. The annealed and pickled delivery condition coupled with anti-corrosive oil coating enhances longevity even in aggressive settings.

Versatile Connection Types & Custom Configurations

Engineered for flexibility, these flanges are available in welded, threaded, lap joint, slip-on, socket welded, blind, orifice, and plate types. Face options include raised face (RF), flat face (FF), and ring type joint (RTJ), providing compatibility with various piping systems and process requirements.

Stringent Quality Control for Reliable Performance

Each flange undergoes 100% Positive Material Identification (PMI), ultrasonic and hydro tests to ensure dimensional precision and leak-proof reliability. With adherence to ASME/ANSI B16.5 standards and thickness up to 30 mm, these flanges are a reliable choice for critical applications.

FAQ's of DUPLEX 2205 Stainless Steel Flanges:

Q: How are DUPLEX 2205 stainless steel flanges typically used in industrial applications?

A: DUPLEX 2205 flanges are primarily used to connect pipes, valves, pumps, and other equipment in industries such as oil & gas, petrochemical, chemical processing, power generation, marine, and water treatment plants. Their robust corrosion resistance and high strength ensure long-lasting, leak-proof connections, even in demanding environments.

Q: What benefits do DUPLEX 2205 flanges offer compared to standard stainless steel flanges?

A: Compared to conventional stainless steel, DUPLEX 2205 flanges provide superior corrosion resistance, higher strength, and improved durability, especially in chloride-rich or acidic environments. This performance makes them ideal for applications where reliability and extended service life are critical.

Q: When should I choose a raised face (RF), flat face (FF), or ring type joint (RTJ) flange?

A: The choice depends on pressure, temperature, and gasket compatibility. Raised face (RF) is common for moderate to high pressures, flat face (FF) for low-pressure systems and non-metallic gaskets, while ring type joint (RTJ) is suitable for high-pressure, high-temperature applications requiring metal-to-metal sealing.

Q: What quality control processes are applied to DUPLEX 2205 flanges before delivery?

A: All flanges undergo rigorous inspection, including 100% Positive Material Identification (PMI), ultrasonic testing, and hydrostatic pressure tests, to ensure compliance with ASME/ANSI B16.5 and international standards. This ensures product reliability and consistency for critical usage.

Q: Where can DUPLEX 2205 flanges be sourced in India and in what packaging options are they supplied?

A: These flanges can be sourced from a network of dealers, manufacturers, suppliers, distributors, traders, and wholesalers across India. For safe transport, they are packed in wooden cases, pallets, or bubble wrapping to prevent damage during shipping or storage.

Q: How do you ensure corrosion resistance during transport and storage?

A: DUPLEX 2205 flanges receive anti-corrosive oil coating and are supplied in annealed and pickled condition, which, along with secure packaging, protects them from oxidation or moisture exposure during transit and storage.
