Petroleum, petrochemical and natural gas industries - Cathodic protection of pipeline systems - Part 1: On-land pipelines (ISO 15589-1:2015)

ISO 15589-1:2015 specifies requirements and gives recommendations for the pre-installation surveys, design, materials, equipment, installation, commissioning, operation, inspection, and maintenance of cathodic protection systems for on-land pipelines, as defined in ISO 13623 or EN 14161 for the petroleum, petrochemical, and natural gas industries, and in EN 1594 or EN 12007‑1 and EN 12007‑3 used by gas supply industries in Europe.
All contents of this part of ISO 15589 are applicable to on-land pipelines and piping systems used in other industries and transporting other media such as industrial gases, waters, or slurries.
ISO 15589-1:2015 applies to buried pipelines, landfalls of offshore pipeline sections protected by on-shore based cathodic protection installations, and to immersed sections of on-land pipelines such as river or lake crossings.
ISO 15589-1:2015 specifies requirements for pipelines of carbon steel, stainless steel, cast iron, galvanized steel, or copper. If other pipeline materials are used, the criteria to apply are defined under the responsibility of the pipeline operator.
ISO 15589-1:2015 does not apply to pipelines made of reinforced concrete for which EN 12696 can be applied.
NOTE Special conditions sometimes exist where cathodic protection is ineffective or only partially effective. Such conditions can include shielding (e.g. disbonded coatings, thermal-insulating coatings, rocky soil, etc.) and unusual contaminants in the electrolyte.

Erdöl- und Erdgasindustrie - Kathodischer Schutz für Transportleitungsysteme - Teil 1: On-land pipelines (ISO 15589-1:2015)

Dieser Teil von ISO 15589 legt Anforderungen fest und enthält Empfehlungen hinsichtlich Voruntersuchungen, Konstruktion, Werkstoffen, Ausrüstung, Installation, Inbetriebnahme, Betrieb, Inspektion und Instandhaltung von kathodischen Korrosionsschutzsystemen für Rohrleitungen an Land, wie sie in ISO 13623 oder EN 14161 für die Erdöl-, petrochemische und Erdgasindustrie und in EN 1594 oder EN 12007 1 und EN 12007 3 für die Gasversorgungsindustrie in Europa festgelegt sind.
Der gesamte Inhalt dieses Teils von ISO 15589 ist anwendbar auf Rohrleitungen an Land und Rohrleitungssysteme, die in anderen Industriezweigen verwendet werden und andere Medien transportieren, wie industrielle Gase, Wässer oder Schlämme.
Dieser Teil von ISO 15589 gilt für erdverlegte Rohrleitungen, Anlandungen von Offshore-Rohrleitungsabschnitten, die durch kathodische Korrosionsschutzanlagen an Land geschützt sind, sowie für in Gewässern liegende Abschnitte von Rohrleitungen an Land, wie bei Fluss- oder Seeüberquerungen.
Dieser Teil von ISO 15589 legt Anforderungen an Rohrleitungen aus unlegiertem Stahl, nichtrostendem Stahl, Gusseisen, verzinktem Stahl oder Kupfer fest. Werden andere Rohrleitungswerkstoffe eingesetzt, werden die anzuwendenden Kriterien unter der Verantwortung des Rohrleitungs-Betreibers festgelegt.
Dieser Teil von ISO 15589 gilt nicht für Rohrleitungen aus Stahlbeton, für die die Norm EN 12696 angewendet werden kann.
ANMERKUNG   Besondere Bedingungen treten gelegentlich auf, bei denen der kathodische Korrosionsschutz unwirksam oder nur teilweise wirksam ist. Solche Bedingungen können eine Abschirmung (z. B. enthaftete Umhüllungen, Wärmedämmung, felsiger Boden usw.) sowie ungewöhnliche Verunreinigungen im Elektrolyt umfassen.

Industries du pétrole, de la pétrochimie et du gaz naturel - Protection cathodique des systèmes de transport par conduites - Partie 1: Conduites terrestres (ISO 15589-1:2015)

L'ISO 15589-1:2015 spécifie les exigences et donne des recommandations pour les études de préinstallation, la conception, les matériaux, l'équipement, l'installation, la mise en service, l'exploitation, l'inspection et la maintenance des systèmes de protection cathodique destinés aux conduites terrestres, comme défini dans l'ISO 13623 ou l'EN 14161 relatives aux industries du pétrole, pétrochimiques et du gaz naturel et dans l'EN 1594 ou l'EN 12007‑1 et l'EN 12007‑3 utilisées par les industries de fourniture en gaz en Europe.
Tout le contenu de la présente partie de l'ISO 15589 est applicable aux conduites terrestres et aux systèmes de conduites utilisés dans d'autres industries et transportant d'autres fluides comme les gaz industriels, les eaux ou les boues liquides.
La présente partie de l'ISO 15589 s'applique aux canalisations enterrées, aux atterrages de tronçons de canalisations en mer protégés par des installations de protection cathodique basées à terre et aux tronçons immergés de canalisations terrestres tels que des traversées sous fluviales.
L'ISO 15589-1:2015 spécifie les exigences concernant les canalisations en acier au carbone, en acier inoxydable, en fonte, en acier galvanisé ou en cuivre. Si d'autres matériaux sont utilisés pour les canalisations, les critères à appliquer sont définis sous la responsabilité de l'exploitant des canalisations.
L'ISO 15589-1:2015 ne s'applique pas aux canalisations constituées de béton armé pour lesquelles l'EN 12696 peut être appliquée.
NOTE Dans des conditions particulières, la protection cathodique peut s'avérer inefficace ou seulement partiellement efficace. De telles conditions peuvent comprendre un effet d'écran (par exemple, des décollements de revêtements, des revêtements thermo-isolants, un sol rocheux, etc.) et la présence de contaminants inhabituels dans l'électrolyte.

Petrokemična industrija ter industrija za predelavo nafte in zemeljskega plina - Katodna zaščita cevovodov - 1. del: Cevovodi na kopnem (ISO 15589-1:2015)

Standard ISO 15589-1:2015 določa zahteve in podaja priporočila za prednamestitvene preglede, projektiranje, materiale, opremo, namestitev, začetek uporabe, delovanje, preglede in vzdrževanje sistemov katodne zaščite za cevovode na kopnem, kot je določeno v standardu ISO 13623 ali EN 14161 za petrokemično industrijo ter industrijo za predelavo nafte in zemeljskega plina, ter v standardih EN 1594 ali EN 12007 1 in EN 12007 3 za industrijo dobave zemeljskega plina v Evropi.
Vsa vsebina tega dela standarda ISO 15589 se uporablja za cevovode na kopnem in cevovodne sisteme, ki se uporabljajo v drugih industrijah, ter za transport drugih medijev, kot so industrijski plini, vode ali brozge.
Standard ISO 15589-1:2015 se uporablja za vkopane cevovode, priobalne odseke cevovodov na morju, ki so zaščiteni z napravami za katodno zaščito na kopnem, in za potopljene odseke cevovodov na kopnem, kot so prehodi rek ali jezer.
Standard ISO 15589-1:2015 določa zahteve za cevovode iz ogljikovega jekla, nerjavnega jekla, železove litine, galvaniziranega jekla ali bakra. Če so za cevovode uporabljeni drugi materiali, je za merila za uporabo pristojen upravljavec cevovoda.
Standard ISO 15589-1:2015 se ne uporablja za cevovode iz armiranega betona, za katere se uporablja standard EN 12696.
OPOMBA: Včasih obstajajo posebni pogoji, pri katerih je katodna zaščita neučinkovita ali le delno učinkovita. Taki pogoji lahko zajemajo plast (npr. neoprijemni premazi, toplotnoizolacijski premazi, kamnita tla itd.) ter neobičajna onesnaževala v elektrolitu.
