High pressure piping life expectancy
High pressure piping life expectancy
(OP)
Hi,
I need to determine the life expectancy of high pressure piping (stainless Steel), between 600 to 3600 lbs in a compressed air system maintained at -80C dew point. The system is located inside, so it is not subjected to rain, snow, or UV. The air flowing inside the pipes is very dry.
We have had a very good long term experience with these systems (>30 years), but in my search for life expectancy determination, I would like to be able to use technical data, standards, tests (maybe Xrays) to determine the life expectancy of the system. I basically want to be backed by real values. If a thickness test is done, what criteria should i use in determining the piping is still in good condition? Standard?
Thank you very much for your help!

I've seen 50 year old plants with carbon steel air lines.

The idea of an experienced inspector calculating and taking the necessary measurements is very interesting.
Is the API accreditation the only one usually used in piping? Does it refer to ASME or ANSI for the acceptable criteria? I have never worked with API standards before...
Thanks!
