ABSTRACT:
A liquid storage tank and flanged valve attachment for the tank are disclosed. The storage tank includes a double bottom wall, with the inner bottom wall formed to slope downwardly from all corners of the tank toward a discharge member. Such a downward slope is provided by forming a downwardly sloping channel from each corner of the tank toward the point of discharge, and with the planar surfaces of the upper wall between the channels being also sloped accordingly. Between the two bottom walls, a structural, insulating or vibration dampening material is provided so as to make the inner and outer bottom walls integral for superior strength and vibration resistance. A flanged discharge arrangement is provided for the discharge member in one embodiment. The flanged discharge includes a casting attached to the inner and outer bottom walls, and with holes for receiving bolts to secure a valve to the casting.
