Good morning:
I am looking for a definition of sour service for hydrocarbon piping systems
Thanks,

According to ISO 15156
'Exposure to oilfield environments that contain H2S and can cause cracking of materials by the mechanisms addressed by ISO 15156 Part 1'

RE: NACE Definition of Sour Service
Does anyone know if we could use any other pressure such as the system design pressure or the normal operating pressure?
Thx
RE: NACE Definition of Sour Service
Since SSC is a non age related degradation mechanism and is dependent upon pH2S, it is prudent to calculate pH2S from system DESIGN pressure in gas containing systems. The actual choice would be dependent upon the likelihood of achieving design pressure within the pressure system. See the thread in process engineering thread798-227400: Operating, Design and Overdesign values which has everyone in a fluster.
