Governing Standards

ASTM A105 Covers forged carbon steel piping components for ambient- and higher-temperature service in pressure  systems. Included are flanges, fittings, Valves, and similar parts ordered  either to dimensions specified by the purchaser or to dimensional standards.
ASME   B16.11 Covers ratings, dimensions, tolerances, marking and material requirements for socket-welding and threaded  forged fittings. These fittings are designated as Class 2000, 3000, and 6000 for threaded end fittings and Class 3000, 6000, and 9000 for socket-weld end fittings.
