Learn about types of flange faces: Flat Face (FF), Raised Face (RF), Ring Joint (RTJ), Tongue and Groove (T&G), and Male and Female types.

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.

In this article, we will learn about various types of flange faces and types of flange face finishes. Types of Flange Faces The ASME B16.5 and ASME B16.47 standards refer to six different types of flange faces.

What is a flange face? There are three common types of flange face, the plain/flat, raised, and ring-type joint (RTJ). Other types of flange face exist, primarily the Tongue-and-Groove (T&G), Lap Joint, and Male-and-Female (M&F) designs, but these are less popular.

Flange face standards define the exact geometry and dimension of the part of the flange that is in contact between faces. 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).

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.

2024年10月1日 · Learn about the different types of flange face as we talk about flange facing & when to use raised-face and flat-face flanges for optimal performance.

Different flange face types accommodate various pressure levels, temperature ranges, and gasket materials — making it essential for engineers to choose the correct type for each application. This guide will cover the common flange face types, their applications, and maintenance practices to help you select the right option for your project.

Flanges are of various types which can be selected according to the site requirement. In order to match the design of an ideal flange, reliable operations must be ensured along with this long service life and an optimal pricing should be taken care of. Scroll down to have a look at the most common flange types which are usually available. 1.

Flat face flanges are combined with the cast iron fittings to get an enhanced output. Ring type joints [RTJ]: It is also referred to as metal to metal sealing process. Therefore, it is applicable in high pressure and high temperature environmental conditions. Testing and Quality assurance Flanges once manufactured are passed through several tests.
