Selection of flange

Dear all,

Could anyone of u answer the following query :

There is a nozzle in a Vessel (which is a closed drain sump). I have to select a flange for the nozzle and the piping to follow. How will I select the type of flange whether ring, RF etc..

The nozzles sizes are 2", 4", 6", 8". Based on the selection of flange I will also have to order the bolts.
The bolt sizes can be obtaibed fron B16.5. Can anyone tell me how to selectthe type of flange to be used.

Thanks in advance
Jijoy
