How to calculate the setting of a pressure balanced safety joint?
(OP)
I have a piping configuration where a feeder pipline (4" S/80 API 5L Gr. B) ties into a receiving pipeline subsea (as shown on the attached). The feeder pipeline travels parallel to the receiving pipeline just before it 90's into the receiving pipeline. Just before the feeder pipeline travels parellel to the receivng pipeline, there will be a pressure balanced safety joint installed. What is the "industry accepted method" of calculating the setting of the pressure balanced safety joint? I have used Ceasar II pipe stress software but my numbers do not match some hand calcs that were done. Thanks for your help.

You'll have to check with the mfgr about the calculations for set pressure.
