A rubberized flange is a type of mechanical joint used in piping systems, particularly where there is a need for flexibility, sealing, or vibration absorption. These flanges are typically made from metal flanges that have a rubber gasket or rubber lining added to their sealing surface. The rubber serves to enhance the sealing properties, improve flexibility, and provide insulation from vibrations or thermal expansion.

Rubberized flanges are commonly used in industries where fluid or gas must be contained within pipes, but the joints need to accommodate movement or offer high sealing efficiency.

Rubberized flanges are used in a variety of applications, particularly where there is a need to ensure a tight seal under pressure or in situations involving temperature fluctuations or mechanical stress. Some common uses include:

1. Piping Systems:

   • Used in water treatment plants, chemical plants, oil and gas pipelines, and industrial systems to ensure a leak-proof seal.

2. HVAC Systems:

   • Employed in ventilation, heating, and air conditioning systems to prevent leaks and reduce vibrations in the piping.

3. Fluid and Gas Handling:

   • Used in the pharmaceutical, food and beverage, and petrochemical industries to handle various fluids and gases with an assurance of leak-proof connections.

4. Marine and Offshore:

   • Commonly used in marine and offshore applications (such as ships and platforms) for fluid and gas transport systems where both flexibility and sealing are critical.

5. Automotive:

   • Utilized in engine piping, exhaust systems, and fuel lines where the seal integrity needs to be maintained under varying pressures and temperatures.

6. Vibration Control:

   • Especially used in machinery and pumps where minimizing vibration transmission is crucial.

Rubberized flanges consist of two main components:

1. Metal Flange: The flange itself is typically made of steel, stainless steel, or ductile iron. The flange’s role is to provide a structural connection and support for the rubber gasket or lining.

2. Rubber Gasket or Lining: The rubber part is usually a gasket that fits between the mating surfaces of two flanges or a lining that covers the sealing area. The rubber is usually made from materials such as:

   • Nitrile rubber (NBR): Suitable for oil and fuel resistance.
   • EPDM: Resistant to high temperatures, weather, and ozone.
   • Silicone rubber: For high-temperature and food-grade applications.
   • Neoprene: For general chemical resistance.

• Variety of Rubber Materials: Rubberized flanges are available in a variety of rubber types to suit different applications, such as high temperature, chemical resistance, or food-grade applications.
• Sealing Efficiency: The rubber gasket or lining provides a superior seal to prevent leakage, especially in high-pressure systems.
• Temperature Resistance: Rubber materials used in flanges can be resistant to both high and low temperatures, ensuring the flange maintains its integrity.
