Frequently Asked Questions on Elbow Fittings
Key engineering, tolerance, and international compliance answers from our metallurgical quality desk.
Long radius elbows have a centerline radius of 1.5 times the nominal pipe size, while short radius elbows have a radius equal to the nominal size. Long radius elbows are preferred for smoother flow and lower pressure drop.
