45°ELBOW

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

It is a standardized and high-quality pipe fitting designed to facilitate smooth directional changes in fluid flow. This revised version adheres to the ASME B16.11-2016 standard, ensuring the latest engineering practices and safety guidelines are met.

With its precise 45-degree angle, it optimizes fluid conveyance in various industrial applications, providing reliable and efficient performance. The threaded or socket-weld end connection allows for easy installation and compatibility with other ASME B16.11 compliant fittings, making it a versatile and trusted choice for piping systems.
