Description
A dual expansion joint can be used to gain larger axial movement than a single piping expansion joint can handle. Triad’s dual metal expansion joints consist of two single expansion joint bellows connected by a center pipe. This expansion joint as with the single metal bellows expansion joints relies on the piping system to be anchored in order to function properly. An intermediate anchor base may be incorporated into the dual metal bellows design to withstand the forces required to move either bellows but still requires the use of main anchors.
