Abstract

A hopper tee for redirecting the flow of material from one passage to another passage includes a radius providing a transition between the passages. A port at the exterior of the radius includes an upwardly-open cavity having a bottom wall disposed within the radius and forming a sacrificial wall extending between the bottom wall and the inner surface of the radius. The cavity provides an indication that material moving through the tee has worn the wall of the radius by the creation of a passage between the interior of the tee and the cavity and expelling material through the passage to the exterior of the tee. A plug may be secured within the cavity allowing a user to continue to use the tee until the tee is rotated or replaced. The radius may include a thickened wall for providing added structural support and sacrificial material.
