ANSI B16.5 / ASME B16.47 Raised Face Flange Supplier, Manufacturer in India

ANSI B16.5 / ASME B16.47 Raised Face Flange Supplier, Manufacturer

Unichem Steel & Alloy Pvt. Ltd. is the most noteworthy Manufacturer, Supplier, and Exporter of Raised Face Flange in India. The Raised Face Flange is that the most common type utilized in process plant applications and is simple to identify. it’s mentioned as a Raised Face Flange because the gasket surfaces are raised above the bolting circle face. This face type allows the utilization of a good combination of gasket designs, including flat ring sheet types and metallic composites like a spiral wound and double jacketed types. Raised Face Flanges (RF flanges) are widely used for oil & gas pipelines and are easy to recognize because the gasket surface is found above the bolting line of the flange. RF Face Flanges are compatible with a good range of gaskets, from the flat cut types to the metallic and semi-metallic sorts of jacketed gaskets and spiral wound gaskets. the most goal of Raised Face Flanges is to concentrate the contact pressure on a little area of the flange thus increasing the strength of the seal. the height of the raised surface depends on the rating of the flange and is defined by ASME B16.5 (for pressure classes 150 and 300, the height of raised face shall be approx. 1.6 mm, while, for classes from 400 to 2500, The Raised Face Flange height shall be approximately 6.4 mm (1/4 inch). the foremost common Flange Face finish for ASME B16.5 RF Flanges is 125 to 250 micron Ra (3 to six micron Ra). A Raised Face Flange (RF) is simple to recognize because the gasket area is positioned above the bolting line of the flange. A Raised Face Flange is compatible with a good range of flange gaskets, starting from flat to semi-metallic and metallic types, either ring or full face. Raised Face Flanges are the foremost sold sort of flange, at least for petrochemical applications.
