This Standard is to be used in conjunction with equipment described in other volumes of the ASME B16 Series of Standards as well as with other ASME standards, such as the Boiler and Pressure Vessel Code and the B31 Piping Codes.Д¬areful application of these B16 Standards will help users to comply with applicable regulations within their jurisdictions, while achieving the operational, cost and safety benefits to be gained from the many industry best-practices detailed within these volumes. Also included in this Standard are requirements and recommendations regarding flange bolting, flange gaskets, and flange joints. Customary units are provided.Д«16.5 is limited to flanges and flanged fittings made from cast or forged materials, and blind flanges and certain reducing flanges made from cast, forged, or plate materials.

ISO (Metric Size Drills) & Conversion to InchesДЇractional and Metric Sizes per. The need for tolerances to be identified on drawings is vital to allow assembly of parts in the desired way and interchangeability. The tolerance of size is normally defined as the difference between the upper and lower dimensions. The drill size chart contains twist drill data for up to 1.0 inches in diameter.ДЇor typical mechanical tolerances that are achievable see: Drilling Tolerances Capabilities Chart ANSI Size Drill Bit Chart Tables of standard tolerance grades and limit deviations for holes and shafts Notes. Fractional sizes are measured in inches, while metric sizes are measured in millimeters. ANSI/ASME B94.11M-1993 below are the standard size drill bits used and readily available in industry.
