Rf Ff Rtj Flange Face And Finish 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. Above the bolting line of the flange. a raised face flange is compatible with a wide range of flange gaskets, ranging from flat to semi metallic and metallic types (as, for example, jacketed gaskets and spiral wound gaskets), either ring or full face. the main scope of a raised face flange design is to concentrate the pressure of the two.
Flange Face Ff Rf Rtj And Finish Types Smooth Serrated Stock 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”. Pipe flanges manufactured in accordance with asme b16.5 may generally be furnished with 3 types of facing: raised face (rf), ring type joint face (rtj), and flat face (ff). the use of rtj flanges always requires the use of a metallic ring gasket, which has a very smooth, mirror like finish. the side wall surface finish of the gasket groove. The typical flange face finish for asme b16.5 rf flanges is 125 to 250 µ in ra (3 to 6 µ m ra). raised face height for the height measures h and b of all described dimensions of flanges on this website, with exception of the lap joint flange, it is important to understand and remember the following. By piping mart december 19, 2020. there are six types of flange faces which are flat (ff), raised (rf), lap joint, ring joint (rtj), male and female (m&f), and tongue and groove (t&g). in various types of flanges, different types of gaskets are required to make connections.

Selecting the right flange face for valve installations is crucial to ensuring system performance and safety. this comprehensive guide explores the differences between raised face (rf), flat face (ff), and ring type joint (rtj) flanges, helping engineers make informed decisions based on pressure, temperature, material compatibility, and application needs. discover best practices and case. 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.
