ABSTRACT:
An integral one-piece hopper tee is disclosed as providing a generally vertically directed hollow pipe section having a laterally outwardly direct flange at an upper end thereof for attachment to the bottom of a hopper truck. At the other end of the vertical pipe section, a generally transversely extending hollow pipe section is provided, with the opposite free ends thereof capable of being attached to pipeline tubing, through which pneumatic unloading of product obtained in the hopper truck may be routed first through the vertically and horizontally directed pipe sections and then into the pipeline tubing. In the area of juncture between the generally vertically and horizontally directed pipe sections, smooth and uninterrupted internal transitional surfaces are provided to permit complete and continuous flow of product discharged from the hopper into the vertically directed pipe section, and subsequent flowing without impedance into the generally horizontally extending pipe section, for entry into pipeline tubing connected thereto. An inner molded lining having a low coefficient of friction conforming to the smooth and uninterrupted internal transitional surfaces may also be used.
