ASME B16.5 flanges are a set of American Society of Mechanical Engineers (ASME) standards that define the dimensions, materials, and tolerances for pipe flanges and flanged fittings. The standard covers flanges made from cast or forged materials, and blind flanges and certain reducing flanges made from cast, forged, or plate materials. It also includes requirements and recommendations regarding flange bolting, flange gaskets, and flange joints. The ASME B16.5 standard is used in conjunction with other ASME standards, such as the Boiler and Pressure Vessel Code and the B31 Piping Codes. It is also widely accepted in other countries, and is often referred to as the ANSI B16.5 standard. The ASME B16.5 standard defines six types of flanges: Weld neck flanges Slip-on flanges Socket weld flanges Threaded flanges Lap joint flanges Blind flanges Reducing flanges Each type of flange has different dimensions and requirements. For example, weld neck flanges have a neck that is welded to the pipe, while slip-on flanges are simply slipped over the pipe. The ASME B16.5 standard is an important reference standard for the design, construction, and installation of piping systems. It ensures that flanges and flanged fittings are safe and reliable, and that they can withstand the pressures and temperatures of the application.
