Corrosion probe sampling frequency

[DiegoMartinez]

Guys,

Is there anyone who can provide a guideline on frequency of sampling of the corrosion probes at the plant inlet and slug catcher in a sweet natural gas plant?

Thanks

Once per month should be enough. With a sweet gas plant, that may be too high a frequency to read anything, however you probably need to set that as the minimum documentation level.

Probes or coupons? If the former, you can have them on a datalogger; if the latter, it will be based upon the expected corrosion mechanisms within the system, allowance for a stabilisation period, and previous observations.
