Different types of flange faces are used as the contact surfaces to seat the sealing gasket material. ASME B16. 5 and B16. 47 define various types of flange facings, including the raised face, the large male and female facings which have identical dimensions to provide a relatively large contact area.
Flange facing refers to the process of machining the mating surfaces of flanges to achieve a smooth and flat finish, ensuring proper alignment and a leak-free seal when two flanges are bolted together. Flange facing is a critical step in the assembly of piping systems, pressure vessels, and other equipment where a secure and reliable connection is essential.
There are different types of flange facing, and the choice depends on the specific requirements of the application. Here are some common types:

Flange Facing Type & Finish Manufacturer

Flange Facing Type & Finish Exporter
Manufacturer and Exporter of Flange Facing Type & Finish in Dimension accordance with ANSI/ASME B16.5, B 16.47 Series A & B, B16.48, BS4504, BS 10, EN-1092-1, DIN, etc. Certified with NACE, PWHT, HIC, SSC, Magnetic Particle Test, Dye Penereteration Test etc.
Raised Face (RF)
- The most common type of flange facing.
- Involves machining a small, raised portion around the flange's opening.
- The raised face provides a sealing surface for gaskets.
Flat Face (FF)
- The flange facing is completely flat without any raised portions.
- Suitable for applications where a metal-to-metal seal is desired, often used with a gasket.
Ring Type Joint (RTJ)
- Features a groove around the flange face where a metallic gasket (ring) is placed.
- Typically used in high-pressure and high-temperature applications.
Tongue and Groove (T&G)
- Involves machining a tongue (protrusion) on one flange and a corresponding groove on the other.
- Provides improved alignment and stability, commonly used in large-diameter flanges.
Male and Female (M&F)
- Similar to tongue and groove, but with a male protrusion on one flange and a corresponding female recess on the other.
- Enhances alignment and prevents flange rotation.

What is a Flange Facing Type & Finish?
The flange face surface is the area where the sealing element (gasket) is installed. The most common flange face surface designs are smooth and serrated. Flat face (FF) flange surfaces and raised face (RF) flange surfaces require serrations if built to industry standards.
Smooth or Serrated
Flange surface faces can be classified as smooth (also called ‘flat’ or ‘plain’) or serrated. Smooth faces appear visually ‘smooth’ and have no visual tool markings. Serrated faces have some form of tool markings on the flange face.
Surface Finish
The 'finish' of a flange face surface denotes the final qualities of the sealing surface. A flange face can be smooth or serrated, but further machining operations can be performed to refine the precise finish of each type of surface. For example, a flange surface could be smooth, but how smooth? A serrated flange surface has serrations, but what is their depth, number, and geometry? These qualities, as well as the allowed roughness value, govern how a flange surface is finished.
Smooth Flange Surfaces Finish
Smooth flange surfaces appear to be flat and featureless when evaluated visually. For flat face flanges, the smooth flange surface covers the full flange face. The smoothness of the surface is determined by how much machining the flange face has received. Metallic/hard gaskets must be mated to smooth finished surfaces or a seal will be difficult to achieve.
