Adapter coupling

Abstract

A coupling for joining a flanged pipe element to a non-flanged pipe element has segments that are connected end to end and surround a central space. Flange portions extend from one side of the segments. Each segment defines two channels, one of which receives a split ring for gripping the non-flanged pipe; the other channel receives a seal. A flanged tube is also positioned between the segments. The flange of the tube is positioned adjacent to the flange portions of the segments. The seal engages the tube and the non-flanged pipe element. The flange portions of the segments are bolted to the flange of the flanged pipe element and the flange of the tube is captured between the flanged portions of the segments and the flange of the flanged pipe element.
