Discussion on material selection for hydrogen sulfide corrosion
20972.3 Petroleum and natural gas industry: Materials used in oil and gas extraction in hydrogen sulfide-containing environments. Is the indication shown by the arrow incorrect?
Limitations of duplex stainless steel: Why are there no requirements regarding the partial pressure of hydrogen sulfide for any equipment or component in oil and gas processing and injection units that are in operation after separation? And 0599 specifies that in an environment with a high hydrogen sulfide content (5%), the partial pressure of hydrogen sulfide exceeds the operational limits for martensitic stainless steel, precipitation-hardening stainless steel, or duplex stainless steel. ”

1. If it contains only hydrogen sulfide (without chloride ions, carbon dioxide, etc.), can carbon steel resistant to SSC as listed in SY/T 0599 be used regardless of the partial pressure of hydrogen sulfide? 2. Contains only hydrogen sulfide (no chloride ions, carbon dioxide, etc.). Under what operating conditions (temperature, pressure) is it better to choose stainless steel? 3. When hydrogen sulfide, chloride ions, and carbon dioxide coexist, what material should be chosen?
Control hydrogen sulfide concentration to reduce manufacturing stress!
