How can flanges be classified based on facing?

Question

Accepted Answer

Flanges can be classified based on facing into several types.

Flanges can be classified as flat face (FF), raised face (RF), ring type joint (RTJ), tongue and groove (T&G), and male and female (M&F) facing.
Flat face (FF) flanges have a flat surface and are used for low-pressure applications.
Raised face (RF) flanges have a raised surface to provide a sealing area and are commonly used in medium to high-pressure applications.
Ring type joint (RTJ) flanges have a groove and are used with metal ring gaskets for high-pressure and high-temperature applications.
Tongue and groove (T&G) flanges have a tongue on one flange and a matching groove on the other, providing alignment and sealing.
Male and female (M&F) flanges have a male face on one flange and a corresponding female face on the other, allowing easy alignment and sealing.
