Governing Standards

ASME B16.20 Covers metal ring-joint gaskets, spiral-wound gaskets, metal-jacketed gaskets, and grooved metal gaskets with covering layers.
ASME B16.47 Covers pressure-temperature ratings, materials, dimensions, tolerances, marking, and testing for pipe flanges in sizes NPS 26 through NPS 60. Included are flanges with rating class designations 75, 150, 300, 400, 600, and 900 with requirements given in both SI (Metric) and U. S. Customary units, with diameter of bolts and flange bolt hole expressed in inch units.
