15、 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 committee has been established has the right to be represented on that
16、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 electrotechnical standardization. International Standards are drafted in acc
17、ordance 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 member bodies for voting. Publication as an International Standard requ
18、ires 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 identifying any or all such patent rights. ISO 14313 was prepared by Technic
19、al Committee ISO/TC 67, Materials, equipment and offshore structures for petroleum, petrochemical and natural gas industries, Subcommittee SC 2, Pipeline transportation systems. This second edition cancels and replaces the first edition (ISO 14313:1999), which has been technically revised, principal
20、ly by the following. Clause 2, on the requirements for conformity to this International Standard, has been added for clarification. Clause 7, on the requirements for allowable stresses and allowable deflection on design, has been revised and clarified. Clause 8, on material, has been revised to alig
21、n the requirements with global industry practice for carbon content and carbon equivalent for pressure-containing, pressure-controlling, welding ends and parts requiring welding. New requirements on repairs and NDE of welding repairs have been added to Clause 9 on Welding. A new table (Table D.2) ha
22、s been added to Annex D (informative) to provide more guidance for those requirements listed in the text as requiring agreement between the manufacturer/purchaser. ISO 14313:2007(E) vi ISO 2007 All rights reservedIntroduction This International Standard is the result of harmonizing the requirements
23、of ISO 14313:1999 and API Spec 6D-2002 5 . The revision of ISO 14313 is developed based on input from both ISO/TC67/SC2 WG2 and API 6D TG technical experts. The technical revisions have been made In order to accommodate the needs of industry and to move this International Standard to a higher level
24、of service to the petroleum and natural gas industry. Users of this International Standard should be aware that further or differing requirements can be needed for individual applications. This International Standard is not intended to inhibit a manufacturer from offering, or the purchaser from acce
25、pting, alternative equipment or engineering solutions for the individual application. This may be particularly applicable where there is innovative or developing technology. Where an alternative is offered, the manufacturer should identify any variations from this International Standard and provide
26、details. INTERNATIONAL STANDARD ISO 14313:2007(E) ISO 2007 All rights reserved 1 Petroleum and natural gas industries Pipeline transportation systems Pipeline valves 1 Scope This International Standard specifies requirements and provides recommendations for the design, manufacturing, testing and doc
27、umentation of ball, check, gate and plug valves for application in pipeline systems meeting the requirements of ISO 13623 for the petroleum and natural gas industries. This International Standard is not applicable to subsea pipeline valves, as they are covered by a separate International Standard (I
28、SO 14723). This International Standard is not applicable to valves for pressure ratings exceeding PN 420 (Class 2 500). 2 Conformance 2.1 Units of measurement In this International Standard, data are expressed in both SI units and USC units. For a specific order item, unless otherwise stated, only o
29、ne system of units shall be used, without combining data expressed in the other system. For data expressed in SI units, a comma is used as the decimal separator and a space is used as the thousands separator. For data expressed in USC units, a dot (on the line) is used as the decimal separator and a
30、 comma is used as the thousands separator. 2.2 Rounding Except as otherwise required by this International Standard, to determine conformance with the specified requirements, observed or calculated values shall be rounded to the nearest unit in the last right-hand place of figures used in expressing
31、 the limiting value, in accordance with the rounding method of ISO 31-0:1992, Annex B, Rule A. 2.3 Compliance to standard A quality system should be applied to assist compliance with the requirements of this International Standard. NOTE ISO/TS 29001 gives sector-specific guidance on quality manageme
32、nt systems. The manufacturer shall be responsible for complying with all of the applicable requirements of this International Standard. It shall be permissible for the purchaser to make any investigation necessary in order to be assured of compliance by the manufacturer and to reject any material th
33、at does not comply. ISO 14313:2007(E) 2 ISO 2007 All rights reserved3 Normative references The following referenced documents are indispensable for the application of this document.
