Suitability of SS316 + TCC for sour service 1

[Hisham Al. Mohammad]

Hi all,

I am working on a project where the service conditions & design parameters are as below:

P = 460 bar = 10,000 psi
T = 120 deg C & Operating temp = 65 -80 deg C
The medium is a gas containing 9% H2S with a partial pressure = 41.4 bar

My question is:
Is SS316 + TCC "Tungsten Carbide Coating" suitable for this severe sour service? If not, any recommendations for a suitable material?
I need to get your kind answers with evidence, please.
