ANSI ASME B16 11 2011 – Forged Fittings, Socket-Welding and Threaded
American Society of Mechanical Engineers / 30-Jan-2012 / 32 pages
ISBN: 9780791934015

This ANSI ASME B16 11 2011 Standard 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.

ANSI ASME B16 11 2011 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.

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 wrought and forged fittings with pressure equipment, plus all potential governing entities.
