90 DEGREE ELBOW
ASME B16.11-2016 (Revision of ASME B16.11-2011)
Is a standardized pipe fitting designed to provide a smooth directional change of fluid flow by 90 degrees. This revised version adheres to the ASME B16.11-2016 standard, ensuring high-quality manufacturing and safety compliance.
The fitting’s threaded or socket-weld end connection allows for easy installation and compatibility with other ASME B16.11 compliant components, making it a reliable and versatile choice for piping systems.

(*) 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).
