TEE
ASME B16.11-2016 (Revision of ASME B16.11-2011)
is a standardized pipe fitting, revised from ASME B16.11-2011, designed with a T-shaped configuration to provide a 90-degree branch connection between three pipes. This fitting allows for the smooth flow of fluids in multiple directions, making it essential for various industrial applications.
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 complex piping systems that require branch connections.

Dimension B represents the minimum length of an impeccable thread. The total length of the functional thread, comprising B and threads with fully formed roots and crests, must meet or exceed the L2 requirement (effective length of external thread) prescribed by the American National Standard for pipe threads (ANSI / ASME B1.20.1).
