ASME B31.3 Intrumentation
ASME B31.3 Intrumentation
(OP)
I was wondering if anyone knows whether or not ASME B31.3 addresses requirements for piping instrumentation e.g. pressure and temperature gages. When I read through the exclusions for B31.3, instrumentation was not listed yet when I look through B31.3, there are no specifics in regards to requirements. Input would be much appreciated.

Tubing typically used in my industry (Oil&gas, upstream, produced water) is mainly to ASTM-A-269 or -213.
RE: ASME B31.3 Intrumentation
Are there specific B31.3 pressure gage requirements? My understanding is that inline instrumentation is subject to B31.3 rules whereas non-inline instrumentation is not and is considered an unlisted component that must meet the piping system design requirements.
What is your feeling about this?
