Elbows are manufactured with a flange on each end of a curved section of tubing. ANCORP ASA/ANSI elbows are offered in 3 designs: 45° radius elbow, 90° radius elbow, and 90° mitered elbow to accommodate a wide variety of system configurations and conductance requirements. ANCORP offers flanges on these fittings in two styles: fixed and rotatable. Fixed flanges have a set bolt hole orientation whereas rotatable flanges have a two piece design allowing for bolt hole rotation to assist bolt hole alignment when mating the two flanges. ANCORP manufactures standard elbows in 304 stainless steel. Other materials are available on request.
