H2S pitting

[Nicknackwhack]

Hi Guys,

Can you point me in the direction of any good (visual) examples of H2S pitting in lines with approximately 50 Barg pressure and 50 C temperature
With ppm's in the region of 2000 for CO2 and 1000 for H2S. This would be on carbon steel pipework

I suspect that the resultant pits would be highly localised due to the high ratio of H2S to CO2 but I cant find any good examples,


Cheers,

Nick
