ASME B16.11 Threaded 90 Degree Elbows Dimension

ASME B16.11 Threaded 90℃ Elbows are crucial pipe fittings in piping systems for achieving a 90℃ change in fluid direction. They connect to pipes via internal or external threads at both ends, eliminating the need for welding and offering easy assembly and disassembly. They are widely used in applications such as petroleum, chemical, natural gas, and civil water supply and drainage systems that require frequent maintenance or operate under low-pressure conditions.

Refers to the outer diameter of the elbow's connection end after beveling. This dimension must match the outer diameter of the connecting pipe.

Center-to-End Dimension: Refers to the perpendicular distance from the centerline of the elbow to the end face of either port. This is a critical dimension for determining the pipe layout space. ASME B16.11 90℃ elbows are typically short-radius type, with a smaller center-to-end dimension, facilitating installation in confined spaces.

ASME B16.11 threaded elbows typically use American Standard tapered pipe threads. A minimum thread length is required to ensure sufficient engagement length for effective sealing.
