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.
