Gaskets provide proper sealing between flange connections in a system in order to prevent the leak or escape of the fluid being moved in the system. Gaskets are used in many different industries and play a large role in process system Raised Face Height.

The raised face also helps to distribute stress evenly across the gasket, which improves the seal and reduces the chance of gasket failure.

Flat Face (FF) The Flat Face flange has a gasket surface in the same plane as the bolting circle face. Applications using flat face flanges are frequently those in which the mating flange or flanged fitting is made from a casting. Flat face flanges are never to be bolted to a raised face flange. ASME B says that when connecting Gasket Flanges Manufacturers in Mumbai India. We offer Comprehensive Range of Gasket Flanges in SS /L, SS /L as per the international quality standards – ANSI B, ANSI B, ANSI B, ANSI B, BS , EN, UNI /, DIN, JIS, SABS, GOST in Class – LBS, LBS, LBS, LBS, For example, a raised face to flat-face flange connection will result in leakage from the joint, per ASME code B Raised face flanges. The most common type is the raised face flange. Its name comes from the raised gasket surface, above the bolting circle face. The raised face concentrates more pressure on a smaller gasket area RTJ flanges, in general, have a raised face with the groove into the face of the flange, but the raised face doesn’t contain the pressure similar to weld neck raised face flanges. Refer to Fig. 1, which gives an example of a typical RTJ flange assembly. The raised face may be present in a ring-type joint flange but it does not contain the Style - Full Face Gaskets for lb ASME/ANSI Pipe Flanges. Phelps carries large inventory of gasket material for a wide range of application in many industries including water treatment, refineries, food processing, power plants, and other industrial applications. Although 1/8" and 1/16" are the most commonly ordered thickess, we carry a Flanges rated # and # have a 1 / 16 ″ raised face, whereas flanges # and above have a ¼″ raised face (see Figure ). It is important to note that the most dimensioning charts, including the ones provided in this chapter, include the 1 / 16 ″ raised face thickness in the length dimensions for # and # flanges.

A raised flange is a type of pipe flange that is raised above the pipe when installed. Flat flanges are typically used for low-pressure applications, while raised flanges are used for high-pressure applications. Flat flanges are easier to install than raised flanges, as they do not require welding. Raised flanges provide a better seal than flat Bolt two flat-surface flanges or two raised-surface flanges of the same size together with a gasket (sold separately) to create an access point in a pipe line. Slip-on weld flanges have no internal stop; slide a pipe through the flange and weld on both sides. For technical drawings and 3-D models, click on a part number
