What Is A Raised Face Flange?


ASME B16.5 Raised Face Flanges dimensions vary according to the use cases. The rf flange dimensions 300 are according to the pressure class of 300. Carbon Steel Raised Face Flanges can have different pressure classes such as RF Flanges. Raised Face Flanges are one of the most commonly used types. Stainless Steel Raised Face Flanges are used for their durability in piping systems. The specification ANSI B16.5 Raised Face Flanges contains a range of up to NPS24 Raised Face Flanges. Raised Face Flanges have their gasket surfaces above their bolting circles. They can come up to 60 inches of diameter in the ASME B16.47 Series A and B Raised Face Flanges standard.

How Do You Attach A Flat Face Flange To A Raised Face Flange?

Class 600 RF Flanges, Their pressure classes differ such as the raised face (rf) flanges as well. The usage of different types and compositions depend on the requirement. The oil refineries, chemical plants and food processing plants require different types. The flat face raised face flange connection are much stronger, durable and could be used in a duplex steel piping system. ductile iron raised face flanges are common in chemical systems and the Alloy 20 Raised Face Flanges has a different specialty. The ASME B16.5 Raised Face Flange is one of the most used standard of flanges.


What Is Ff And Rf Flange?

  • FF Flange : A flat face flange is shortly referred to as FF. This flat face flange is a component which has been machined to be flat and, therefore does not have a ridge like structure as seen in either a raised face or ring type joint flange.

  • RF Flange : Raised Face Flanges have their gasket surfaces above their bolting circles, RF Flanges are used for their durability in piping systems. ASME B16.5 Raised Face Flange is one of the most used standard of flanges.

Nickel Alloy 200 Raised Face Flange is made up of nickel alloy where the ASTM A182 SS Raised Face Flange is of A182 material. In the same manner, the Alloy Steel Raised Face Flanges and the Carbon Steel Raised Face Flange differ in composition. Whatever the case may be, the Raised Face Flange Dimensions can be selected from a variety of standards and materials such as the MSS SP-44 Raised Face Flanges or the Inconel Raised Face Flanges or a different alloyed Hastelloy C22 Raised Face Flange.


Rajtilak Metal is privately owned Carbon Steel Raised Face Flange in India, manufacture with Pressure Classes 150 & 300 and 600, the height of raised face is approximately 1.6 mm (1/ 16 inch). In these three Pressure Classes, almost all suppliers of ANSI Class 150 Raised-Face Flange, show in their catalog or brochure, the H and B dimensions including the raised face height.
