The ASME B16.5 standard specifies in detail the dimensions, pressure and temperature ratings, materials, tolerances, markings, test methods and the designation of openings for flanges and fittings. This standard applies to flanges and fittings with diameters from NPS 1/2 (approx. 25.4 mm) to NPS 24 (approx. 610 mm), where NPS stands for "nominal pipe size", i.e. nominal pipe size.

Here are some key points about ASME B16.5 flange dimensions:

1. ** Rating Classes ** : ASME B16.5 covers classes 150, 300, 400, 600, 900 and 1500 in the size range NPS 1/2 to NPS 24, and class 2500 in the size range NPS 1/2 to NPS 12.

2. ** Material ** : This standard limits flanges and fittings with flanges to be made only from castings or forged parts, and also includes blind flanges and certain reduced diameter flanges made from castings, forged parts or plates.

3. ** Dimensions and tolerances ** : This standard provides detailed dimensional diagrams, including bolt hole diameters and flange dimensions, and specifies tolerance requirements.

4. ** Bolted flange connections ** : This standard contains specific requirements and recommendations for flange bolted connections, flange gaskets and flange joints.

5. ** Units and symbols ** : This standard provides two versions of units, one using metric units and the other using imperial units. The bolt diameter and flange aperture are measured in inches.

6. ** Testing and marking ** : The standard specifies the tests that must be carried out and the marking requirements of the product to ensure compliance with the specified pressure and temperature rating.

** * Harmonization with other ASME Standards ** : ASME B16.5 should be used with other equipment described in the ASME B16 series of standards and other ASME standards such as Boiler and Pressure Vessel codes (BPVC) and B31 piping codes.
