dear friend,
I think the advantages exceeded the
disadvantages if you do testing for a specific
rating(ex. 150#) with only one pressure test rating.
One disadvantage I saw was you need to make
sure that some piping accessories could withstand the
test pressure you'll going to apply. I mean, when a
certain line that you'll be going to test has a
flexible hose or expansion joints, it's better to
check first if that accessories can tolerate that
pressure, otherwise remove it from the line or you
gonna reduce the test pressure as long as it meets the
requirement. But basically I can strongly recommend
testing a certain rating with uniform pressure test,
i.e. to minimize time and money.:-)
Anyway, you can test 150# piping line with 410psig.
