Socket Weld Flange
Our socket weld flange, a kind of pipe flange, is designed and manufactured for use on small diameter and high pressure applications. It is similar to slip-on flange in the fabrication, but it has greater fatigue strength when provided with an internal weld. Since its counter bore is larger than OD of the matching pipe, the pipe can be inserted.
Socket weld flange: 3/8"～3"
