Scope: This part describes and proposes the general principles, requirements and recommended methods for the evaluation and selection of metal materials for equipment in the environment of hydrogen sulfide (H(subscript 2)S) in oil and gas production and desulfurization units. The failure of these devices will bring great harm to the health and life safety of the staff and the public or the environment. This section helps avoid this costly corrosion damage to your equipment. This part supplements rather than replaces the existing material technical requirements in relevant design standards and specifications or detailed rules. This part describes all corrosion cracking mechanisms induced by hydrogen sulfide, including sulfide stress cracking, stress corrosion cracking, hydrogen induced cracking and step cracking, stress oriented hydrogen cracking, soft zone cracking and galvanic couple induced hydrogen stress cracking . Table 1 gives a non-exhaustive list of equipment applicable to this standard, including permitted exceptions. This standard applies to the selection and evaluation of materials used in the design and manufacture of equipment according to conventional elasticity criteria. This section does not necessarily apply to refinery or downstream processing equipment.
