Product Details

EO Flanges can provide ANSI B16.5 Class 300 Socket-Weld Flanges, which Number of Holes from 4 to 8 pcs, Diameter of Holes from 0.63 to 0.88 in, Nominal Pipe Size 0.5 to 3 in, etc. This Standard covers pressure-temperature ratings, materials, dimensions, tolerances, marking, testing, and methods of designating openings for pipe flanges and flanged fittings. RF flanges seal with a flat gasket designed for installation between the raised faces of two mating flanges (both with raised faces). The raised faces have a prescribed texture to increase their gripping and retaining force on this flat gasket. Some users of raised face flanges specify the use of spiral wound gaskets.
