Hi Guys:
I work at an upstream oil and gas plant in Alberta Canada. I understand that different specs on different piping requires a spec break on piping to identify the differences in the specification between two different pipe that are joining together. However, within our plant we have a series of well pads on the same lease as the plant itself. These pads I would say are within a distance of 500 meters to less than 1 km in distance. However, I never did understand why these wells would be built under CSA Z662 for pipeline and then converted back to B31.3 prior to entering the process facility. I was wondering if someone could provide some light on this? I have asked around and cannot get a clear understanding why you would do this? Could you just build the plant and pipeline to CSA Z662 or B31.3? I apologize if this question seems silly.
Thanks for you help
Justin
