Steel 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 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 Ring Type Joint Flange. The Raised face rtj flange is used in applications that need a better and stronger connection usually in gas lines and liquid lines where the pressure is high and the connection has to be sealed with a gasket rather than welding. The Class rtj flange is one of the many pressure classes of the rtj flanges The height and thickness measurements of flanges on [HOST] show all dimensions including the raised face height. The Raised Face Height depends on the pressure The face of a flange is the side opposite the hub that faces the bolted connection of the main flange flange fitting or flange valve. The most common face is the Raised Face flange, such as the one I have here. On this Class flange, we have a 1/inch raised face. On flanges in Class and higher, the raised face is a quarter Easy to access for maintenance and inspection. A blind flange is a type of pipe flange used to seal off the end of a piping system. A raised face flange is a pipe flange with a raised face that provides greater surface area for welding. Blind flanges are typically used in applications where welding is not required, such as in low-pressure
Flange Facing Type & Finish in B16.5 Raised Face Serrated Finish
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 Spiral Flange Face Finish 4. Concentric Serrated Flange Face Finish. Like the spiral serrated finish, the Concentric Serrated Flange Face Finish is intended for high-pressure applications, particularly those involving raised-face flanges. This finish type features a series of concentric grooves machined into the flange face Full face gaskets are used with flat face flanges, see image below. A full face gasket covers the entire surface area of the flange face including bolt holes. Hanna Rubber produces full face gaskets gaskets using non-asbestos, red rubber (Garlock® style 22), Garlock®, Gylon®, Viton, Neoprene, ECH (epichlorohydrin), EPDM (ethylene propylene Ring Gasket ; fits inside the bolt area of a flange and is typically used on raised-face (RF) flange.; It can be dropped into a flange assembly without fully disassembling the joint. Full-Face Gasket ; covers the full surface area of the flange with holes to insert and align the flange bolts.; The joint must be fully disassembled to install Non-metallic: They are generally soft applications made from CNAF, PTFE, rubber, and ceramic fiber. Metallic: They are also a very hard application that is made in the shape of an oval ring or octagonal ring. Composite: With metallic and non-metallic materials, they create very durable flange gasket applications
