Flush type Openings in a Tank
(OP)
As I go through API-650, I read about Flush Type Clean Out Fittings and Flush Type Shell COnnection, As I donot have design back ground, please help me to understand these terms and how they differ from the common fittings we now in a tank?

I would suggest using Finite Element Analysis (FEA) and a competent engineer in such analyses to determine the allowable loading on the nozzle. It is intended in future editions or addenda to incorporate this approach into P.3 which is presently absent.

To carry this farther, this is why the manways on tanks are positioned approximately 180 Degrees from this flush clean-outs, the clean-up crew would enter the tank through the manways with squeegees and brooms to push the gunk remaining in the tank to the flush bottom clean-out door, where the vacuum truck can easily deal with it, and why the flush bottom clean-outs are positioned where it can easily be reached by a vacuum truck.
