30、ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical
31、committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of elect
32、rotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the
33、member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for ident
34、ifying any or all such patent rights. ISO 21329 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore structures for petroleum, petrochemical and natural gas industries, Subcommittee SC 2, Pipeline transportation systems. ENISO21329:2004vi Introduction In some circumstance
35、s mechanical connectors provide a lower cost and/or enabling advantage to welded connectors usually used for pipelines. However, use of mechanical connectors has raised concerns about pipeline integrity due to the potential for leak paths and absence of a direct method of inspection. In the past, re
36、assurance of the integrity of mechanical pipeline connectors has relied upon design information provided by the 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 hence there is
37、 a significant burden in the number of connectors that need to be tested. However, it is recognized that the test burden can be reduced in project-specific cases, for example if there is no concern about fatigue, if the connector will not be subjected to fully restrained forces and/or if the connect
38、or design is less sensitive to accuracy of tolerance matching of components at assembly. The tests specified in this International Standard provide a physical demonstration of the integrity of the pipeline connector. This International Standard has been developed from three main sources. The first i
39、s the Low cost pipeline connector systems joint industry project (JIP), (1995-1997) 14 , which defined the load envelopes for pipelines, identified the practical issues of installation, and conducted demonstration physical tests on three types of mechanical connectors. The second source is ISO 13679
40、, which has a parallel function for downhole connections. The third is the Connection testing specification JIP, (1999-2000) 15 . The JIP was sponsored by oil companies, connector suppliers, pipeline construction contractors and design consultants. ENISO21329:2004INTENRATIONAL TSANDADR IS:92312 O400
41、2(E)1Petroleum and natural gas industries Pipeline transportation systems Test procedures for mechanical connectors 1 Scope This International Standard specifies requirements and provides guidance for the testing of mechanical connectors for use in pipeline transportation systems for the petroleum a
42、nd natural gas industries as defined in ISO 13623. The tests specified in this International Standard are intended to form part of the design verification process for connectors. They provide objective evidence that connectors conform to a defined performance envelope. This International Standard do
43、es not cover the use of design procedures as part of the qualification process for mechanical connectors, nor does it address fabrication and quality control. However, it can be used as input to a qualification procedure. Although its principles can be applied, this International Standard does not a
44、ddress a) 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 or J-tube pulls, f) factory acceptance testing, g) statistical bases for risk analysis. 2 Normative references The following referen
