Bi-metallic flanges ( bi metal flanges ):

Bi-metallic flanges are specialized flange components that are made by bonding two different metals together. These flanges are designed to combine the unique properties of two different metals to provide enhanced performance and durability in challenging environments. The outer ring of the flange is typically made of carbon steel, while the sealing face is composed of a different metal such as stainless steel or alloy steel.

Types of brazing bi-metallic flanges:

1. Bi-metallic slip-on flanges: These flanges feature a carbon steel outer ring and a stainless steel or alloy steel sealing face, offering excellent corrosion resistance and strength.

Material: carbon steel or stainless steel and alloy 

Standard dimensions: ANSI/ASME B16.5 or DIN

2. Bi-metallic weld neck flanges: They provide a robust connection due to the combination of a carbon steel neck and a stainless steel or alloy steel sealing face.

Material: carbon steel or stainless steel and alloy 

Specifications: Bimetallic weld neck flanges are available in various sizes and pressure ratings, conforming to industry standards such as ANSI/ASME B16.5 or DIN.

3. Bi-metallic threaded flanges: These flanges have a carbon steel threaded portion and a stainless steel or alloy steel sealing face, enabling easy installation and secure connections.

Material: an inner ring made of carbon steel or stainless steel, and an outer ring composed of a low expansion alloy.

Specifications: ANSI/ASME B16.5 or DIN.

4. Bi-metallic blind flanges:  these are high quality bi metallic flanges They are designed with a carbon steel outer ring and a stainless steel or alloy steel cover plate, ensuring a reliable seal for closing off a pipe end.

Material: carbon steel or stainless steel and alloy

Specifications: ANSI/ASME B16.5 or DIN.

Benefits of using bi-metallic flanges:

Corrosion resistance:

The combination of carbon steel and stainless steel or alloy steel provides superior corrosion resistance, reducing the risk of leaks and increasing the lifespan of the flange.

Strength and durability:

Bi-metallic flanges offer high strength and durability, making them suitable for demanding applications in various industries.



Bi-metallic flanges can offer cost savings compared to using solid stainless steel or alloy flanges, without compromising performance or reliability.



These flanges can be customized to meet specific requirements, combining different metals to achieve the desired properties.


Wide temperature range:

Bi-metallic flanges can withstand a wide range of temperatures, making them suitable for applications with extreme temperature variations.


But to enjoy these benefits make sure you get them from the best bi-metal flanges supplier in UAE, IRAQ QATAR IRAN SAUDI ARABIA YEMAN EGYPT OMAN AFRICA and RUSSIA.


To sum up,

bi-metallic flanges combine the advantages of different metals to provide superior performance and durability in demanding environments. With their corrosion resistance, strength, versatility, and cost-effectiveness, they are widely used in industries such as oil and gas, chemical and petrochemical, power generation, marine, food and beverage, and water treatment. By choosing bi-metallic flanges, companies can ensure reliable connections, prevent leaks, and enhance the longevity and efficiency of their piping systems. Hence when you buy high-quality bimetallic flanges from the best bimetallic flanges suppliers in uae.
