Petroleum and natural gas industries - Pipeline transportation systems (ISO 13623:2017, modified)

This document specifies requirements and gives recommendations for the design, materials, construction, testing, operation, maintenance and abandonment of pipeline systems used for transportation in the petroleum and natural gas industries.
It applies to pipeline systems on-land and offshore, connecting wells, production plants, process plants, refineries and storage facilities, including any section of a pipeline constructed within the boundaries of such facilities for the purpose of its connection. On-land supply systems used by the European gas supply industry from the input of gas into the on-land transmission network up to the inlet connection of gas appliances are excluded from the scope of this document. The extent of pipeline systems covered by this document is illustrated in Figure 1.
This document applies to rigid, metallic pipelines. It is not applicable for flexible pipelines or those constructed from other materials, such as glass-reinforced plastics.
This document is applicable to all new pipeline systems and can be applied to modifications made to existing ones. It is not intended that it applies retroactively to existing pipeline systems.
It describes the functional requirements of pipeline systems and provides a basis for their safe design, construction, testing, operation, maintenance and abandonment.

Erdöl- und Erdgasindustrie - Rohrleitungstransportsysteme (ISO 13623:2017, modifiziert)

Dieses Dokument legt Anforderungen fest und enthält Empfehlungen hinsichtlich Konstruktion, Werkstoffen, Bauausführung, Prüfung, Betrieb, Instandhaltung und Stilllegung (Aufgabe) von Rohrleitungssystemen, die in der Erdöl- und Erdgasindustrie für Transportzwecke verwendet werden.
Es gilt für Rohrleitungssysteme an Land und Offshore, bei Anschlussbohrungen, in Produktionsanlagen, Prozessanlagen, Raffinerien und für Speichereinheiten, einschließlich aller Rohrleitungsabschnitte, die inner¬halb solcher Einrichtungen zu deren Verbindung verwendet werden. Versorgungssysteme an Land, die von der Europäischen Gasversorgungsindustrie von der Einspeisung des Erdgases in die Rohrleitungstransportsysteme an Land bis zum Eingangsanschluss gasbetriebener Endgeräte benutzt werden, sind vom Anwendungsbereich dieses Dokuments ausgeschlossen. Der Umfang der in diesem Dokument behandelten Rohrleitungssysteme ist in Bild 1 dargestellt.
Dieses Dokument gilt für starre Rohrleitungen aus Metall. Es gilt nicht für flexible Rohrleitungen oder Rohrleitungen aus anderen Werkstoffen, z. B. glasfaserverstärkte Kunststoffe.
Dieses Dokument ist anzuwenden für alle neuen Rohrleitungssysteme und kann für die an den vorhandenen Rohrleitungssystemen durchgeführten Änderungen angewendet werden. Eine rückwirkende Anwendung auf vorhandene Rohrleitungssysteme ist nicht beabsichtigt.
Es beschreibt die funktionellen Anforderungen an Rohrleitungssysteme und dient als Grundlage für deren sichere Konstruktion, Bauausführung, Prüfung, Betrieb, Instandhaltung und Stilllegung (Aufgabe).
