27、tandardization) 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 committee has been established has the ri
28、ght 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 electrotechnical standardization. Internationa
29、l 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 member bodies for voting. Publication as
30、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 identifying any or all such patent rights. ISO
31、 13709 was prepared by Technical Committee ISO/TC 115, Pumps, Subcommittee SC 3, Installation and special application, in collaboration with Technical Committee ISO/TC 67, Materials, equipment and offshore structures for petroleum, petrochemical and natural gas industries, SC 6, Processing equipment
32、 and systems. This second edition cancels and replaces the first edition (ISO 13709:2003), which has been technically revised. vi Introduction It is necessary that users of this International Standard be aware that further or differing requirements can be needed for individual applications. This Int
33、ernational Standard is not intended to inhibit a vendor from offering, or the purchaser from accepting, alternative equipment or engineering solutions for the individual application. This can be particularly appropriate where there is innovative or developing technology. Where an alternative is offe
34、red, it is necessary that the vendor identify any variations from this International Standard and provide details. A bullet ( ) at the beginning of a clause or subclause indicates that either a decision is required or the purchaser is required to provide further information. It is necessary that thi
35、s information should be indicated on data sheets or stated in the enquiry or purchase order (see examples in Annex N). In this International Standard, where practical, US Customary, or other, units are included in parentheses for information. API Standard 610/ISO 13709 1 Centrifugal pumps for petrol
36、eum, petrochemical and natural gas industries 1 Scope This International Standard specifies requirements for centrifugal pumps, including pumps running in reverse as hydraulic power recovery turbines, for use in petroleum, petrochemical and gas industry process services. This International Standard
37、is applicable to overhung pumps, between-bearings pumps and vertically suspended pumps (see Table 1). Clause 9 provides requirements applicable to specific types of pumps. All other clauses of this International Standard are applicable to all pump types. Illustrations are provided of the various spe
38、cific pump types and the designations assigned to each specific type. Relevant industry operating experience suggests pumps produced to this International Standard are cost effective when pumping liquids at conditions exceeding any one of the following: discharge pressure (gauge) 1 900 kPa (275 psi;
39、 19,0 bar) suction pressure (gauge) 500 kPa (75 psi; 5,0 bar) pumping temperature 150 C (300 F) rotative speed 3 600 r/min rated total head 120 m (400 ft) impeller diameter, overhung pumps 330 mm (13 in) NOTE For sealless pumps, reference can be made to API Std 685. For heavy duty pump applications
40、in industries other than petroleum, petrochemical and gas processing, reference can be made to ISO 9905. 2 Normative references The following referenced documents are indispensable for the application of this document.
