25、tors provide a lower cost and/or enabling advantage to weldedconnectors usually used for pipelines. However, use of mechanical connectors has raised concerns aboutpipeline integrity due to the potential for leak paths and absence of a direct method of inspection. In the past,reassurance of the integ

26、rity of mechanical pipeline connectors has relied upon design information provided bythe manufacturer, the results of finite element analysis and past experience.This International Standard is primarily applicable to connectors to be used in a large number, and hencethere is a significant burden in

27、the number of connectors that need to be tested. However, it is recognized thatthe test burden can be reduced in project-specific cases, for example if there is no concern about fatigue, ifthe connector will not be subjected to fully restrained forces and/or if the connector design is less sensitive

28、 toaccuracy of tolerance matching of components at assembly.The tests specified in this International Standard provide a physical demonstration of the integrity of thepipeline connector. This International Standard has been developed from three main sources.The first is the Low cost pipeline connect

29、or systems joint industry project (JIP), (1995-1997)14, which definedthe load envelopes for pipelines, identified the practical issues of installation, and conducted demonstrationphysical tests on three types of mechanical connectors.The second source is ISO 13679, which has a parallel function for

30、downhole connections.The third is the Connection testing specification JIP, (1999-2000)15. The JIP was sponsored by oilcompanies, connector suppliers, pipeline construction contractors and design consultants.EN ISO 21329:2004(E)6 Blank Page EN ISO 21329:2004(E)71 ScopeThis International Standard spe

31、cifies requirements and provides guidance for the testing of mechanicalconnectors for use in pipeline transportation systems for the petroleum and natural gas industries as definedin ISO 13623.The tests specified in this International Standard are intended to form part of the design verification pro

32、cessfor connectors. They provide objective evidence that connectors conform to a defined performance envelope.This International Standard does not cover the use of design procedures as part of the qualification processfor mechanical connectors, nor does it address fabrication and quality control. Ho

33、wever, it can be used asinput to a qualification procedure.Although its principles can be applied, this International Standard does not addressa) connectors that are designed to rotate in use,b) manifolds,c) topsides pipework or piping,d) flanges,e) connectors used in pipelines installed by reeling
