This document describes general principles and gives requirements and recommendations for the selection and qualification of metallic materials for service in equipment used in oil and gas production and in natural-gas sweetening plants in H2S-containing environments, where the failure of such equipment can pose a risk to the health and safety of the public and personnel or to the environment. It can be applied to help to avoid costly corrosion damage to the equipment itself. It supplements, but does not replace, the materials requirements given in the appropriate design codes, standards, or regulations.This document addresses all mechanisms of cracking that can be caused by H2S, including sulfide stress cracking, stress corrosion cracking, hydrogen-induced cracking and stepwise cracking, stress-oriented hydrogen-induced cracking, soft zone cracking, and galvanically induced hydrogen stress cracking.Table1 provides a non-exhaustive list of equipment to which this document is applicable, including exclusions.This document applies to the qualification and selection of materials for equipment designed and constructed using load controlled design methods. For design utilizing strain-based design methods, see Clause5.This document is not necessarily applicable to equipment used in refining or downstream processes and equipment. Table1 List of equipment This document is applicable to materials used for the following equipment Exclusions Drilling, well construction, and well-servicingequipment Equipment exposed only to drilling fluids of controlled composition a Drill bits Blowout preventer (BOP) shear blades b Drilling riser systems Work strings Wireline and wireline equipment c Surface and intermediate casing Wells, including subsurface equipment, gas-liftequipment, wellheads, and christmas trees Sucker rod pumps and sucker rods d Electric submersible pumps Other artificial lift equipment Slips Flowlines, gathering lines, field facilities, and field processing plants Crude-oil storage and handling facilities operating at a total absolute pressure below 0,45MPa (65psi) Water-handling equipment Water-handling facilities operating at a total absolute pressure below 0,45MPa (65 psi) Water injection and water disposal equipment Natural-gas treatment plants — Transportation pipelines for liquids, gases, andmultiphase fluids Lines handling gas prepared for general commercial and domestic use For all equipment above Components loaded only in compression a See ISO15156-2:2020, A.2.3.2.3 for more information. b See ISO15156-2:2020, A.2.3.2.1 for more information. c Wireline lubricators and lubricator connecting devices are not excluded. d For sucker rod pumps and sucker rods, reference can be made to NACEMR0176 .
