ASME B16.11 90° Elbow | SW & THD

SME B16.11 90° elbows are used to change the pipe or flow direction by 90 degrees. They can be furnished with two socket welding (SW) ends, two threaded (THD) ends, or one socket welding end and one threaded end. The SW 90° elbows are available in Class 3000 (sizes from 1/8″ to 4″), Class 6000 (sizes from 1/8″ to 2″), and Class 9000 (sizes from 1/8″ to 2″). The THD 90° elbows are available in Class 2000, Class 3000 and Class 6000 (all in sizes from 1/8″ to 4″).
