PETROLEUM AND NATURAL GAS INDUSTRIES - MATERIALS FOR USE IN H2S-CONTAINING ENVIRONMENTS IN OIL AND GAS PRODUCTION - PART 1: GENERAL PRINCIPLES FOR SELECTION OF CRACKING-RESISTANT MATERIALS (ISO 15156-1:2001, COR. 1:2005, MOD)
This Malaysian Standard describes general principles and gives requirements and recommendations for the selection and qualification of 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 could 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 material requirements given in the appropriate design codes, standards or regulations. This Malaysian Standard 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 Malaysian
