If contract doc. doesn't say and the PMC suggests a diff material, you/your process dept. have to weight the overall cost saving solution and make the decision.
Either to use SS and no inhibitor (or) LTCS with inhibitor.
In case if you are interested to know about tomsol just search in the net for 'Tomsol MSDS' . In case if you are not aware of MSDS, it is the abbreviation of 'Material Safety Data Sheet' which gives more info on the chemical.
With regards,

The Contract document does not specify any additive inhibiters in Glycol present, I believe that LTCS Materials can be used but without additive inhibitors the Acid formation will be there which will be highly risky.
I think Tomsol A 40 or A 65 additives used as inhibitors element in Glycol to prevent Acid formation. But still not clear about this process data.

FYI, we have used LTCS and CS material for Glycol water service in Borouge II project.
Now I do not have process dat with me.
