ASME B16 11-2016 (Revision of ASME B16.11-2011)
Is a standardized pipe fitting, revised from ASME B16.11-2011, designed to seal the end of a pipe. This fitting ensures a secure closure, preventing any leakage and providing protection to the pipe’s contents.
The threaded or socket-weld end connections enable easy installation and compatibility with other ASME B16.11 compliant components, offering a versatile and efficient solution for piping systems..
