Flange Faces Explained Flat Raised Etc Savree Types of flange faces. 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. A raised face (rf) flange has circular shaped sealing face that protrudes from the flange’s bolting circle plane. raised face flanges are available in all pressure classes, and thus for a wide range of pressure and temperature ratings. rf flanges are the most common type of flange employed in the oil and gas and chemical engineering industries.
10 Most Used Types Of Pipe Flanges Their Features Uses And Raised face – rf flange. raised face flange has a small portion around the bore raised from the face. the gasket seat on this raised face. the height of the raised face depends on the flange pressure temperature rating, known as a flange class. for 150# & 300# height of the raised face is 1 16”, and above 300#, it is 1 4”. As a general rule, the most commonly used are flat face flanges (flat face flanges ff), raised face flanges (raised face flanges – rf) or ring type joint (ring type joint flanges rtj or r jf). there are also two less commonly used types of faces: flanges with tongue and groove faces and flanges with male and female faces. as a general rule. The flange face has an area beyond the normal (male) flange face. the other flange or mating flange has a matching recess (female) machined into the face. the female face is 3 16″ deep and the male face is 1 4″ high, both with a smooth finish. the outer diameter of the female face is used to locate and hold the gasket. Flange faces, types of flanges. the flange face is the surface area that hosts the gasket. the 6 available types of flange faces are flat (ff), raised (rf), ring joint (rtj), lap joint, male and female (m&f), tongue and groove (t&g). flanges with different faces (that require different gaskets) shall never be mated to prevent leakage of the joint.

The three more common types of raised face flanges are weld neck, slip on, and blind flanges. 3. ring type joint (rtj) ring type joint or rtj flanges are typically used for more sever applications, particularly for high pressure or high temperature applications. they are designed to provide a leak proof seal in critical environments where.
