Dear Experts,
I have a scenario where a Gas Pipeline has to enter the Gas plant boundaries at one end while the receiving facilities (Pig Receiver & Slug-catcher) are located at other end of the facilities.
I am looking for clear guidelines as I am not comfortable about running the Pipeline (&PIG) through the plant along with other process piping and conflict between 31.3 and 31.8 use in facilities or spec break location.
I believe B31.3/ B31.8 specification break should occurs at the fence or occurs at the “first flange” upstream/downstream of the Barred Tee if pipeline pig traps are used located on the line prior to start of Process Piping.
Thank you for your guidance.
