ÖNORM EN 14163:2002-06

Действует
Petroleum and natural gas industries - Pipeline transportation systems - Welding of pipelines (ISO 13847:2000 modified)
This European Standard specifies the requirements for producing and inspecting girth, branch and fillet welds in
the pipeline part of pipeline transportation systems for the petroleum and natural gas industries meeting the
requirements of ISO 13623.
On-land supply systems used by the gas supply industry are excluded from the scope of the International
Standard.
This European Standard is applicable to the requirements for welding of carbon and low-alloy steel pipes.
Application is restricted to pipes with a diameter of 20 mm and larger and wall thickness of 3 mm or more, and a
specified minimum yield strength of 555 MPa or less. It is also applicable to welding into pipelines, items such as
spools, risers, launchers/receivers, fittings, flanges and pups to pipeline valves.
The welding processes covered are shielded metal arc welding, gas tungsten arc welding, gas metal arc welding,
flux-cored arc welding with and without shielding gas, and submerged arc welding.
This European Standard is not applicable to flash girth welding, resistance welding, solid-phase welding or other
one-shot welding processes, nor to longitudinal welds in pipe or fittings, to hot-tap welding of pipelines in service
or to the welding of process piping outside of the scope of ISO 13623.
NOTE Additional requirements may be necessary for welding of pipeline for particular pipeline operating conditions. These
can include limitations on maximum hardness or strength, minimum impact toughness values, crack tip-opening displacement,
all weld metal tensile testing or bend testing, thermal stress relief or others. Where appropriate, these additional requirements
should be added to the requirements of this European Standard in a project-specific supplement.
Diese Norm legt NUR für Offshore-Rohrleitungstransportsysteme die Bestimmungen für das Schweißen von diesen fest. Die Festlegungen gelten für das Verschweißen von Rohren aus unlegiertem und niedriglegiertem Stahl mittels Rund-, Anschuss- und Kehlnähten. Rohrleitungstransportsysteme für die Gasversorgung an Land fallen NICHT in den Anwendungsbereich dieser Norm.
