BUSHING (ASME B16.11-2016)

BUSHING

ASME B16.11-2016 (Revision of ASME B16.11-2011)

Is a standardized pipe fitting, revised from ASME B16.11-2011, designed to connect two pipes of different sizes. This fitting ensures a smooth and secure transition, reducing the pipe diameter to accommodate the smaller pipe.

The threaded or socket-weld end connections facilitate easy installation, ensuring compatibility with other ASME B16.11 compliant components, providing a versatile and efficient solution for piping systems.

CAUTIONARY NOTE REGARDING HEX BUSHINGS.
Hex head bushings with one-size reduction are not recommended for use in services where they could be exposed to more detrimental external loads and forces compared to internal pressures.
