We typically have 2″ gusseted nozzles on the coke drum, swedged to 1.5″ diameter pipe for the run of carrier and antifoam to each coke drum.  You do not need 2″ pipe for the run of carrier oil and antifoam to each coke drum, unless you are injecting a lot of carrier (not recommended).  2″ pipe is less flexible, as well.  Still, I cannot overemphasize the need to perform proper process hydraulic calculations and piping flexibility models, that take into account the cold and hot coke drum positions and the cold and warm antifoam piping positions.  Best regards – Mitch Moloney
