Petroleum, petrochemical and natural gas industries - Metallic materials resistant to sulfide stress cracking in corrosive petroleum refining environments (ISO 17945:2015)

ISO 17945:2015 establishes material requirements for resistance to SSC in sour petroleum refining and related processing environments containing H2S either as a gas or dissolved in an aqueous (liquid water) phase with or without the presence of hydrocarbon. This International Standard does not include and is not intended to include design specifications. Other forms of wet H2S cracking, environmental cracking, corrosion, and other modes of failure are outside the scope of this International Standard. It is intended to be used by refiners, equipment manufacturers, engineering contractors, and construction contractors.
Specifically, this International Standard is directed at the prevention of SSC of equipment (including pressure vessels, heat exchangers, piping, valve bodies, and pump and compressor cases) and components used in the refining industry. Prevention of SSC in carbon steel categorized under P-No. 1 in Section IX of the ASME Boiler and Pressure Vessel Code (BPVC) is addressed by requiring compliance with NACE SP0472.
ISO 17945:2015 applies to all components of equipment exposed to sour refinery environments (see Clause 6) where failure by SSC would (1) compromise the integrity of the pressure-containment system, (2) prevent the basic function of the equipment, and/or (3) prevent the equipment from being restored to an operating condition while continuing to contain pressure.

Erdöl-, petrochemische und Erdgasindustrie - Metallische Werkstoffe beständig gegen Schwefelwasserstoff-Rissbildung in korrosiver Erdölraffinerieumgebung (ISO 17945:2015)

Diese Internationale Norm legt die Anforderungen an metallische Werkstoffe bezüglich der Beständigkeit gegen SSC in saurer Erdölraffinerieumgebung und verwandten Prozessumgebungen, die H2S entweder als Gas oder gelöst in einer wässrigen (flüssiges Wasser) Phase mit oder ohne Kohlenwasserstoffe enthalten. Diese Internationale Norm enthält keine Konstruktionsvorgaben und ist dafür auch nicht vorgesehen. Andere Formen der nassen H2S-Rissbildung, umweltinduzierte Rissbildung, Korrosion und andere Schadens-mechanismen liegen außerhalb des Anwendungsbereiches dieser Internationalen Norm
Diese Internationale Norm richtet sich speziell auf die Vermeidung von SSC bei Ausrüstungen (einschließlich Druckbehältern, Wärmetauschern, Rohrleitungen, Ventilen und Pumpen- und Kompressorgehäusen) und Ausrüstungsteilen, die in der Raffinerieindustrie verwendet werden. Verhinderung von SSC in unlegiertem Stahl, kategorisiert nach P-Nr. 1 in Abschnitt IX der ASME Boiler and Pressure Vessel Code (BPVC), ist durch die erforderliche Übereinstimmung mit der NACE SP0472 berücksichtigt.
Diese Internationale Norm gilt für alle Bauteile der Ausrüstungen, die einer sauren Raffinerieumgebung (siehe Abschnitt 6) ausgesetzt sind, bei der Versagen durch SSC (1) die Unversehrtheit des druckhaltenden Systems beeinträchtigen würde, (2) die Hauptfunktionen der Ausrüstung verhindern würde und/oder (3) verhindern würde, dass die Ausrüstung wieder in einen Betriebszustand gebracht werden kann, während der Druck aufrechterhalten bleibt.

Industries du pétrole, de la pétrochimie et du gaz naturel - Matériaux métalliques résistant à la fissuration sous contrainte induite par les sulfures pour utilisation dans des environnements corrosifs de raffinage du pétrole (ISO/FDIS 17945:2014)

L'ISO 17945:2015 établit les exigences relatives aux matériaux pour la résistance à la fissuration sous contrainte induite par les sulfures dans les milieux corrosifs liés au raffinage du pétrole et aux traitements associés contenant du H2S soit sous forme de gaz soit dissous dans une phase aqueuse (eau liquide) en présence ou non d'hydrocarbures. La présente Norme internationale ne contient pas (et n'est pas destinée à contenir) des spécifications de conception. Les autres formes de fissuration en milieu H2S humide, de fissuration induite par l'environnement, de corrosion et d'autres modes de défaillance ne relèvent pas du domaine d'application de la présente Norme internationale. Elle est destinée à être utilisée par les raffineurs, par les fabricants d'équipements, les entreprises d'ingénierie et les entreprises de construction.
L'ISO 17945:2015 concerne spécifiquement la prévention de la fissuration sous contrainte induite par les sulfures des équipements (y compris les appareils à pression, les échangeurs de chaleur, les tuyauteries, les corps de vannes et les carters de pompes et de compresseurs) et des composants utilisés dans l'industrie du raffinage. La prévention de la fissuration sous contrainte induite par les sulfures dans un acier au carbone de catégorie P-1, selon la Section IX du code ASME applicable aux chaudières et aux appareils à pression (BPVC), est traitée par une exigence de conformité à la spécification NACE SP0472.
L'ISO 17945:2015 s'applique à tous les éléments d'équipement exposés aux milieux corrosifs d'une raffinerie (voir Article 6), dont la défaillance par fissuration sous contrainte induite par les sulfures (1) compromettrait l'intégrité du système de confinement de la pression, (2) empêcherait le fonctionnement de base de l'équipement et/ou (3) empêcherait la remise en état de marche de l'équipement tout en continuant à contenir la pression.
