ASME B16.9 3D Radius Elbows

August 24, 2020

Technical Drawings

Standard drawing of ASME B16.9 3D radius elbow.

According to ASME B16.9-2018, the standard 3D radius elbow may be furnished in 45° or 90°. Compared to the long radius elbow, its center-to-end dimension is much larger, which is double the length of a corresponding L/R elbow. The center-to-end dimension can be calculated as “3 x NPS” in inch unit. Thus, it provides much smoother flow characteristics.
