Components within a spec ina spec break
Components within a spec ina spec break
(OP)
Hi,
If I have a spec break from ANSI 600 (1440psig) to ANSI 300 (750psig). I believe that means that the lowest working pressure rating for any component in the 300 class region should be 750psig. My question is, is there anything wrong with or any problem with having a component higher than that? say 1000psig rating instrument or valve?

As much as possible, do it right the first time...

Flange class ratings are step changes and are maximum pressures. Any item rated lower than the flange rating will set a lower limit but a higher one won't raise the max working pressure but just cost more.
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.
