18、SO 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 committee. International organizations, gov

19、ernmental 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 accordance with the rules given in the ISO/IEC

20、 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 requires approval by at least 75 % of the membe

21、r 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 15547-2 was prepared by Technical Committee ISO/TC 67, Materials, equipm

22、ent and offshore structures for petroleum, petrochemical and natural gas industries, Subcommittee SC 6, Processing equipment and systems. This first edition of ISO 15547-2, together with ISO 15547-1, cancels and replaces ISO 15547:2000, of which it constitutes a technical revision. ISO 15547 consist

23、s of the following parts, under the general title Petroleum, petrochemical and natural gas industries Plate-type heat exchangers: Part 1: Plate-and-frame heat exchangers Part 2: Brazed aluminium plate-fin heat exchangers API Standard 662 Part 2 / ISO 15547-2ivISO 15547-2:2005(E) ISO 2005 All rights

24、reserved vIntroduction Some of the requirements within this part of ISO 15547 have been extracted from the standards of the brazed aluminium plate-fin heat exchanger manufacturers association (ALPEMA). Users of this part of ISO 15547 should be aware that further or differing requirements may be need

25、ed for individual applications. This part of ISO 15547 is not intended to inhibit a vendor from offering, or the purchaser from accepting, alternative equipment or engineering solutions for the individual application. This may be particularly applicable where there is an innovative or developing tec

26、hnology. Where an alternative is offered, the vendor should identify any variations from this part of ISO 15547 and provide details. A recommended practice is included within this part of this International Standard (see Annex A). This part of ISO 15547 requires the purchaser to specify certain deta

27、ils and features. A bullet (z) at the beginning of a clause or subclause indicates a requirement for the purchaser to make a decision or provide information (for information, a checklist is provided in Annex B). In this part of ISO 15547, where practical, US Customary units are included in parenthes

28、es for information.

29、quirements and recommendations for the mechanical design, materials selection, fabrication, inspection, testing, and preparation for shipment of brazed aluminium plate-fin heat exchangers for use in petroleum, petrochemical and natural gas industries. 2 Terms and definitions For the purposes of this

30、 document, the following terms and definitions apply. 2.1 heat transfer area sum of the primary and secondary heat transfer surface areas of all heat-transfer passages in contact with a stream See Figure 1. Key 1 primary heat transfer surface 2 secondary heat transfer surface NOTE 1 The primary heat

31、 transfer surface within the plate-fin heat exchanger consists of the bare parting sheet and the fin base directly brazed to the parting sheet. NOTE 2 The secondary heat transfer surface is provided by the fins. This area includes both sides of the fins where they are in contact with the fluid. Figu

33、at which pressure-containing elements can be subjected to design pressure EXAMPLE Ambient temperature, process fluid temperature. 2.4 plate-fin heat exchanger heat exchanger consisting of a block (core) of alternating layers (passages) of corrugated fins See Figure 2. NOTE 1 The layers are separated

34、 from each other by parting sheets and sealed along the edges by means of side bars, and are provided with inlet and outlet ports for the streams. The block is bounded by cap sheets at the top and bottom. NOTE 2 All the layers carrying the same stream are connected together by headers (inlet, outlet

35、, intermediate) directly attached by welding onto the brazed core.
