Flange faces are critical in determining the type of gasket required and the sealing performance in a piping system. Each face type is designed to meet specific operational requirements. At Udhhyog, we manufacture flanges with various face types to cater to diverse industrial applications.
What Are Flange Face Types?
The flange face is the surface that comes into contact with the gasket, forming a seal to prevent leaks. Selecting the correct face type ensures compatibility with the intended application and operating conditions.
Major Types of Flange Faces
1. Raised Face (RF)
- Description: The most common flange face type, featuring a slightly raised portion around the bore.
- Advantages:
- Enhances gasket compression for a better seal.
- Ideal for high-pressure and high-temperature applications.
- Applications:
- Oil and gas pipelines.
- Chemical processing.
2. Flat Face (FF)
- Description: A completely flat surface suitable for low-pressure systems.
- Advantages:
- Simple design and easy to install.
- Prevents over-tightening, reducing the risk of flange damage.
- Applications:
- Water treatment plants.
- Low-pressure industrial systems.
3. Ring Type Joint (RTJ)
- Description: Features a groove for a metal ring gasket, offering a robust seal.
- Advantages:
- High resistance to vibration and pressure.
- Excellent for harsh and critical conditions.
- Applications:
- High-pressure steam systems.
- Offshore and petrochemical industries.
4. Tongue and Groove (T&G)
- Description: One flange has a raised tongue, while the other has a matching groove.
- Advantages:
- Provides accurate gasket alignment.
- Ensures a tight seal for medium-pressure applications.
- Applications:
- Industrial piping.
- Applications requiring precise sealing.
5. Male and Female (M&F)
- Description: Similar to T&G but with larger contact surfaces.
- Advantages:
- Offers additional sealing strength.
- Suitable for high-pressure and high-temperature systems.
- Applications:
- Heavy-duty applications.
- Power generation plants.
Choosing the Right Flange Face Type
Pressure and Temperature Requirements:
- For high-pressure applications, opt for RTJ or M&F faces.
- For low-pressure systems, FF faces work well.
Gasket Compatibility:
- Raised face flanges are versatile with soft or metallic gaskets.
- RTJ flanges require metal ring gaskets for a precise fit.
Industry Standards:
- Ensure the flange face type meets ASME or API standards for safety.
