Petroleum, petrochemical and natural gas industries - Test methods for quality control of microstructure of ferritic/austenitic (duplex) stainless steels (ISO 17781:2017)

ISO 17781:2017 specifies quality control testing methods and test conditions for the characterization of microstructure in relation to relevant properties in ferritic/austenitic (duplex) stainless steel components supplied in the solution annealed condition and fabrication welds in the as welded condition.
ISO 17781:2017 supplements the relevant product and fabrication standards with respect to destructive testing methods including sampling of test specimens, test conditions and test acceptance criteria to show freedom from deleterious intermetallic phases and precipitates in duplex stainless steels. In addition, this document specifies the documentation of testing and test results by the testing laboratory.
NOTE 1       This document is based upon experience with duplex stainless steels in offshore oil and gas industry applications including topside and subsea hydrocarbon service, sea water service, as well as structural use.
NOTE 2       The austenite spacing is relevant to the susceptibility of duplex stainless steels to hydrogen-induced stress cracking (HISC) in subsea applications where cathodic protection is applied. This falls outside the scope of this document. Reference is made to DNV/GL RP-F112[4].

Industries du pétrole, de la pétrochimie et du gaz naturel - Méthodes d'essai pour le contrôle de la qualité de la microstructure des aciers inoxydables austénitiques/ferritiques (duplex) (ISO 17781:2017)

ISO 17781:2017 spécifie les méthodes et les conditions d'essai de contrôle de la qualité pour caractériser la microstructure par rapport aux propriétés pertinentes des composants en acier inoxydable ferritique/austénitique (duplex) fournis à l'état recuit et les soudures de fabrication à l'état brut de soudage.
ISO 17781:2017 complète les normes de fabrication du produit concerné par rapport aux méthodes d'essais destructifs, y compris le prélèvement des éprouvettes, les conditions d'essai et les critères d'acceptation des essais, pour démontrer l'absence de phases intermétalliques préjudiciables et de précipités dans les aciers inoxydables duplex. De plus, le présent document précise la documentation des essais et des résultats des essais par le laboratoire d'essai.
NOTE 1    Le présent document se fonde sur l'expérience acquise avec des aciers inoxydables duplex dans des applications de plates-formes d'extraction en mer de pétrole et de gaz, y compris dans le cadre d'un fonctionnement en milieu hydrocarbure sous-marin ou en surface ou en service dans l'eau de mer ou pour une utilisation structurelle.
NOTE 2    L'espacement austénitique est pertinent pour la sensibilité des aciers inoxydables duplex à la fissuration par contrainte induite par l'hydrogène (HISC) dans les applications sous-marines en présence d'une protection cathodique. Cela ne relève pas du domaine d'application du présent document. Cela relève du domaine d'application du DNV/GL RP-F112[4].

Petrokemična industrija ter industrija za predelavo nafte in zemeljskega plina - Preskusne metode za kontrolo kakovosti mikrostrukture avstenitno-feritnega (dupleksnega) nerjavnega jekla (ISO 17781:2017)

Ta dokument določa preskusne metode za kontrolo kakovosti in preskusne pogoje za karakterizacijo mikrostrukture glede na ustrezne lastnosti komponent iz avstenitno-feritnega (dupleksnega) nerjavnega jekla, ki so dobavljene v žarjenem stanju, in proizvodnih zvarov v varjenem stanju.
Ta dokument dopolnjuje ustrezne standarde proizvodov in izdelave v zvezi s porušitvenimi preskusnimi metodami, vključno z vzorčenjem, preskusnimi pogoji in merili sprejemljivosti preskusa, za dokazovanje neprisotnosti zdravju škodljivih intermetalnih faz in izločkov v dupleksnih nerjavnih jeklih. Dokument poleg tega določa dokumentacijo za preskušanje in rezultate preskusa iz laboratorija za preskušanje.
OPOMBA 1: Ta dokument temelji na izkušnjah z dupleksnimi nerjavnimi jekli, ki se uporabljajo v industriji za predelavo nafte in zemeljskega plina, med drugim v sistemih za rokovanje z ogljikovodiki, sistemih za rokovanje z morsko vodo in uporabo v strukturah na palubi in pod morsko gladino.
OPOMBA 2: Avstenitni razmak je pomemben za določanje občutljivosti dupleksnega nerjavnega jekla na inducirano vodikovo napetostno pokanje (HISC) pri uporabi pod vodo, kjer se uporablja katodna zaščita. Slednje ne spada na področje uporabe tega dokumenta. Dokument se sklicuje na dokument DNV/GL RP-F112[4].
