Dear All,

What should be the design pressure of natural gas gathering lines if Well Shut In pressure is 3400 psig while gathering line operating pressure is 1000 - 800 psig.


Any recommendations or resources that could be helpful in this regards.


Thank you in advance.

Because of consequences of failure, I would design piping for 2200 psig or so. If existing pipe were rated above 1600 psig that might be okay to use, but I would beef that up for a new system. If the upper management wanted to accept more risk, then that decision would be on them.
