Upon request from industry and government, ASME has been defining piping safety since 1922. This Standard covers metal ring-joint gaskets, spiral-wound gaskets, metal-jacketed gaskets, and grooved metal gaskets with covering layers. It also covers spiral-wound metal gaskets and metal-jacketed gaskets for use with raised-face and flat-face flanges. B16.20 offers comprehensive solutions applying to materials, dimensions, tolerances and marking. It addresses gaskets that are dimensionally suitable for use with flanges described in reference flange standards ASME B16.5, ASME B16.47, API Specification 6A, and ISO 10423 as well as with other ASME standards, such as the Boiler and Pressure Vessel Code and the B31 Piping Codes. Notable revisions to the 2012 edition include a new chapter on Grooved Metal Gaskets with Covering Layers and updates to material tables. Careful 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. Intended for manufacturers, owners, employers, users and others concerned with the specification, buying, maintenance, training and safe use of metallic gaskets with pressure equipment, plus all potential governing entities
