Flat Face (FF):
The Flat Face flange facing is characterized by a smooth, flat surface perpendicular to the pipe axis. It is suitable for low-pressure applications where sealing is achieved with a gasket between the flange faces. Flat face flanges are easy to align and provide a large contact area for the gasket, ensuring a reliable seal.
Raised Face (RF):
The Raised Face flange facing features a raised portion around the bore, creating a step that provides additional contact surface for the gasket. This facing type is suitable for moderate pressure and temperature applications. The raised face helps protect the gasket and provides a more effective seal compared to flat face flanges.
Tongue and Groove (T&G):
Tongue and Groove flange facing consists of a raised ring (tongue) on one flange face and a matching depression (groove) on the other. When the two flanges are mated, the tongue fits into the groove, creating a tight seal without the need for a gasket. T&G flanges are often used in applications where leakage prevention is critical, such as high-pressure and high-temperature environments.
Male and Female (M&F):
Male and Female flange facing is similar to T&G facing but with a different geometry. The male flange has a raised portion (male face), while the female flange has a matching depression (female face). When assembled, the male face fits into the female face, creating a tight seal without a gasket. M&F flanges are used in applications where leakage prevention and ease of assembly are important factors.
Ring Type Joint (RTJ):
Ring Type Joint flange facing features a groove around the flange bore where a metal ring gasket is placed. When the flanges are bolted together, the ring gasket is compressed between the flange faces, forming a tight seal. RTJ flanges are commonly used in high-pressure and high-temperature applications where standard gaskets may fail.

Just great ,thank you and Ramadan Karim

[@TheHinaiibrahim]

Thanks, I learned a lot and enjoyed your simple and special way in explaining.

[@salimjaved3117]

Pls share video on anti surge valve working, safety

[@mitronite]

Excellent content. What would be the best choice of flange if i need an excellent inner surface interface between two pipes with perfect square edges, where the weld joint doesnt create any disturbance.?

[@anirudhaghadel3688]

Lots of information as usual ❤❤

Is that RTJ really octagonal? In the picture it's hexagonal.. 5.15

[@AsadPassionateEngineer]

Hahaha .... Nice Catch ... It is Octagonal design😊 the diagram needs to be updated.
Thanks for Your Observation 😊
