Acceptance Testing- Sampling Hook-ups

[code1]

Please suggest information on necessary hook-ups that detail the mech/instrument requirements for a process plant.

Sampling needed for flow, pressure and temperature, and fluids: superheated steam (40 bar/ 410 deg. C), saturated steam (270 deg. C), condensate, feed water, and flue gases.

Perhaps one way is to talk to the third party who will conduct the tests, but at this point I do not have access to one.

Thanks.

This seems like a big question. Please clarify the acceptance testing requirements. See what is covered in the contract.

For internal plant instruments, typically the checkout requires approved data sheets, loop diagrams, etc. in a folder with an inspection test document that is signed by the technician and client verifying the function and calibration.

The initial startup acceptance testing may require the composition of the inlet gas and the processed gas to assure the heating value, moisture, and other components such as H2S and CO2 comply with a contract. Custody transfer flow meters may require a portable meter prover or other commercial verification.

Hi JL Seagull:
Thanks for the reply. The contract requirements are sketchy.

I am coming from the angle for the need to provide for test points and test nozzles, e.g. blinded nozzles for temperature measurements (thermowells). How can I obtain information on these standard hookups used for test measurements (i.e. during performance tests).

Am I okay to follow to standard plant instrument hook-ups (which I possess), e.g. for pressure, temperature, flow, or will the requirements for test points differ. E.g. good size to use (1/2"? 2"?) and connection (NPT, flanged...?)

Reason for post is I can't get a clear answer from my relevant colleagues (frustrating), this is why I am opening the question to the field.
