Flanges availbale in various forms and size, standards like ASME B16.5 flanges, ASME B16.47 Flanges and ASME B16.36 flanges.These all standards availble in all type of flanges like Weld Neck Flanges, Blind Flanges, Spectacle Blind flanges, Slip on flanges, Orifice flangesand Threaded Flanges etc.
B16.47 Large Diameter Steel Flanges: NPS 26 through NPS 60 This Standard covers pressure-temperature ratings, materials, dimensions, tolerances, marking, and testing for pipe flanges in sizes NPS 26 through NPS 60 and in ratings Classes 75, 150,0300, 400, 600, and 900. Flanges may be cast, forged, or plate (for blind flanges only) materials. Requirements and recommendations regarding bolting and gaskets are also included.
The American Society of Mechanical Engineers issues standards for mechanical and piping design. ASME standard B16.47 covers large diameter pipes up to a 60-inch bore. ASME standard B16.7 series A flanges are equivalent to MSS SP44 flanges. ASME standard B16.7 series B matches API 605 flanges.
