Building on the previous findings regarding the high risk of SSCC in H₂S-H₂O environments, targeted preventive measures can be implemented from multiple perspectives: in terms of material selection, it is necessary to use materials resistant to SSCC that meet the NACE MR0175/ISO 15156 standards; the hardness of carbon steel/low-alloy steel should be kept at ≤HRC22, and pure steel with low sulfur and phosphorus content should be used. Additionally, duplex stainless steels and high-nickel alloys can be employed to handle harsh operating conditions. Stress state optimization involves keeping the working tensile stress in the steel below 60% of its yield limit; weld residual stresses are eliminated through post-weld heat treatment, thereby avoiding local stress concentration caused by cold working. Control of environmental parameters: Maintain the pH value of the system within the range of 9–11 to reduce the degree of ionization of H₂S; at the same time, control the partial pressure of H₂S and the flow rate of the medium in order to minimize the penetration of hydrogen atoms into the steel. Auxiliary protective measures include the use of amine-based corrosion inhibitors to prevent corrosion reactions, as well as coatings such as epoxy resin and polyurethane to isolate metals from corrosive agents; when necessary, cathodic protection techniques are employed to further reduce the risk of hydrogen embrittlement.
