Abstract
A one piece cast hopper tee having a vertically directed hollow pipe section with a flange at an upper end thereof for attachment to the bottom of a hopper truck. The bottom end of the vertical pipe section flares outward at the juncture with a generally horizontal pipe section creating a generally elliptical opening from the vertical pipe into the horizontal pipe. In the area of juncture between the two pipes smooth and uninterrupted internal transition surfaces are provided to permit complete and continuous flow of product from the vertical pipe to the horizontal pipe. A pair of wear saddles, one on each side of the external juncture of the flared section of vertical pipe with the horizontal pipe create wear resistant areas having approximately double the wall thickness of the pipe sections. A substantially thicker wall section is formed in the horizontal pipe opposite the elliptical opening.
