on site corrosion inspection
(OP)
Hello there
I will be sent from my company to verify some chillers where the customer claims to have corrosion.
I have thought that some factors need to be observed, as
proximity to sea
proximity to traffic or chemnies
humidity level
frequency of rain
maintanance procedure
frame condition
Of course I will have to verify if the fins are brittle or not.
Please, are there other elements you would recommend me to observe ?
Thanks in advance !

RE: on site corrosion inspection
I would like to add the below points. (if it is a chiller unit)
Condition and type of insulation
Check for presence of condensation
Shutdown frequency
verify MDMT of the construction materials with the actual.
Check the lowest temperature, the components of the chiller units went through
RE: on site corrosion inspection
please, may I ask you two clarifications ?
1 - please what do you mean for MDMT ? Minimum design metal temperature ?
If so, it is not clear to me how this is related to corrosion
2 - I shall check lowest temperature since there there may be condensation and therefore potential corrosion ?
One further clarification: what if I notice the fins are corroded ?
Many thanks

I visited a site that was a few miles from the beach, but a seawater canal ran right behind an adjacent tree line.

To Mr. EdStainless
many thanks
indeed I followed your piece of advice.
One question: do you think that a chiller set near a parking and a motorway can be subjected to potential corrosion because of pollution due to engines ?
Many thanks
RE: on site corrosion inspection
1. Do they salt the roads in winter to clear ice? (this would lead to chloride contamination)
2. In this in a country with little or no pollution control on cars? (this would greatly increase exposure to acid gases, both sulfurous and nitric)
If either of these are true then it could be a major factor.
