Bottom Tank Connections
Bottom Tank Connections
(OP)
Group
I have a customer that is wanting a cone bottom tank (sloping to center) built. Starting at the center of the tank will be a trough that will run all the way to the edge of the tank to an outlet.
The customer is using 5.8.2 as the justification for being able to use a trough in the bottom of the tank.
5.8.2 states "Connections to the tank bottom are permitted subject to agreement between the Purchaser and the Manufacturer with respect to details that provide strength, tightness and utility equal to the details of shell connections specified in this standard.
Are we reading this statement correctly in that the customer/manufacturer can add a trough in the bottom head and still stamp the tank as API-650

What kind of stamp have you mentioned. API nameplate? Before you "stamp" it, the design has to be reviewed by the Client and you could submitt only an API 650 complying design. If he insists on including a design of his own, not complying with Appendix O (please note that O.2.3 has mentioned pipe, not trough), you withdraw your guarantees and he'll be responsible for the tank safety. He cannot have it both ways. Cheers,

Anyone have any sketches or drawings to share on this design?
What limitations should there be on trough depth, floor thickness, etc ?
I am a little confused about the foundation...is extensive grouting required ??
