10、ervedForeword 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 whic
11、h 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 Electrotechnical Commission (IEC) on all ma
12、tters of electrotechnical 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 circ
13、ulated to the 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 respons
14、ible for identifying any or all such patent rights. ISO 15590-3 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. ISO 15590 consists of the following
15、 parts, under the general title Petroleum and natural gas industries Induction bends, fittings and flanges for pipeline transportation systems: Part 1: Induction bends Part 2: Fittings Part 3: Flanges ISO 15590-3:2004(E) ISO 2004 All rights reserved vIntroduction Users of this part of ISO 15590 shou
16、ld be aware that further or differing requirements may be needed for individual applications. This part of ISO 15590 is not intended to inhibit a manufacturer from offering, or the purchaser from accepting, alternative equipment or engineering solutions for the individual application. This can be pa
17、rticularly applicable where there is innovative or developing technology. Where an alternative is offered, the manufacturer should identify any variations from this part of ISO 15590 and provide details.

21、of ISO 15590. This part of ISO 15590 is not applicable to integrally cast or forged flanges for valves, pumps or other equipment. This part of ISO 15590 does not cover the selection of the flange category or pressure class. Sizes and pressure classes listed in ISO 7005-1 and applicable to this part
22、of ISO 15590 are as follows: DN 10 (NPS 1/2) to DN 1500 (NPS 60); PN 20 (class 150), PN 50 (class 300), PN 100 (class 600), PN 150 (class 900), PN 250 (class 1500), PN 420 (class 2500). 2 Normative references The following referenced documents are indispensable for the application of this document.
