The work of preparing International Standards is normally carried out through ISO technical committees. Each mem
15、ber body interested in a subject for which a technical 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 El
16、ectrotechnical Commission (IEC) on all matters of electrotechnical standardization. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different type
17、s of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). 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
18、held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents). Any trade name used in this document is informa
19、tion given for the convenience of users and does not constitute an endorsement.

The committee responsible for this document is Technical Committee ISO/TC 67, Materials, equipment and offshore structures for petroleum, petrochemical and natural gas industries, Subcommittee SC 2, Pipeline transportation systems for the petrol
21、eum and natural gas industries. This second edition cancels and replaces the first edition (ISO 13847:2000), which has been technically revised. The following annexes have been added compared with the first edition: branch and filet welding on in-service pipelines (Annex D); welding of European onsh
22、ore natural gas transmission pipelines (Annex E); welding of gas distribution systems in Europe (Annex F); automatic ultrasonic testing of girth welds (Annex G); time of flight diffraction techniques (Annex I). ISO 2013 All rights reserved v ISO 13847:2013(E) Introduction Users of this International
23、 Standard are advised that further or differing requirements might be needed for individual applications, using alternative engineering solutions, particularly where there is innovative or developing technology. Where an alternative is offered, it is advisable that the manufacturer identifies any va
24、riations from this International Standard and provides details.vi ISO 2013 All rights reserved INTERNATIONAL ST ANDARD ISO 13847:2013(E) Petroleum and natural gas industries Pipeline transportation systems Welding of pipelines 1 Scope This International Standard specifies requirements for the petrol
25、eum, petrochemical and natural gas industries, for producing and inspecting girth, branch and fillet welds in the pipeline part of pipeline transportation systems which meet the requirements of ISO 13623:2009 or equivalent. This International Standard is applicable to the requirements for welding of
26、 carbon and low-alloy steel pipes, and includes guidance for the welding of corrosion-resistant alloy (CRA) and CRA-clad pipelines in Annex A. Application is restricted to pipes with a diameter of 20 mm or more and a wall thickness of 3 mm or more, a specified minimum yield strength of 555 MPa or le
27、ss, and which are designed not to exceed permissible equivalent stresses as defined in ISO 13623:2009 or equivalent. It is also applicable to welding into pipelines of items such as spools, risers, launchers/receivers, fittings, flanges and pup pieces to pipeline valves. Guidance for special welding
28、 applications is provided in: Annex B for hyperbaric welding; Annex C for brazing and aluminothermic welding of anode leads; Annex D for branch and fillet welding on in-service pipelines. The welding processes covered are shielded metal arc welding (SMAW), gas tungsten arc welding (GTAW), gas metal
29、arc welding (GMAW), gas-shielded flux-cored arc welding (GSFCAW), self-shielded flux-cored arc welding (SSFCAW) and submerged arc welding (SAW). This International Standard is not applicable to flash girth welding, resistance welding, solid-phase welding or other one-shot welding processes, nor to l
30、ongitudinal welds in pipe or fittings or to the welding of process piping outside the scope of ISO 13623:2009. NOTE 1 Additional requirements might be necessary for the welding of pipeline for particular pipeline operating conditions, for pipelines with a specified yield strength exceeding 555 MPa a
31、nd for pipelines designed to permissible strain criteria. 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, it is advisab
32、le that these additional requirements be added to the requirements of this International Standard in a project-specific supplement. NOTE 2 Annex E specifies additional requirements for the welding of onshore gas supply systems applicable only when located in European member states. Annex F specifies
33、 additional requirements for the welding of gas distribution systems applicable only when located in European member states. It is the responsibility of the company to specify the normative applicability of these annexes. 2 Normative references The following documents, in whole or in part, are norma
