23、 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 which a technical committee has been established has
24、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 matters of electrotechnical standardization. Intern
25、ational 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. Publicati
26、on 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 responsible for identifying any or all such patent right
27、s. ISO 10441 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore structures for petroleum, petrochemical and natural gas industries, Subcommittee SC 6, Processing equipment and systems. This second edition cancels and replaces the first edition (ISO 10441:1999), which ha
28、s been technically revised. EN ISO 10441:2007vi Introduction This International Standard was developed from the API Std 671, 3rd edition, 1998. It is intended that the 4th edition of API Std 671 will be identical to this International Standard. Users of this International Standard should be aware th
29、at further or differing requirements may be needed for individual applications. This International 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 may be particularly appro
30、priate where there is innovative or developing technology. Where an alternative is offered, the vendor should identify any variations from this International Standard and provide details. This International Standard requires the purchaser to specify certain details and features. A bullet () at the b
31、eginning of a subclause or paragraph indicates that either a decision is required or further information is to be provided by the purchaser. This information should be indicated on the datasheet(s), typical examples of which are included as Annex J; otherwise it should be stated in the quotation req
32、uest or in the order. EN ISO 10441:20071Petroleum, petrochemical and natural gas industries Flexible couplings for mechanical power transmission Special-purpose applications 1 Scope This International Standard specifies the requirements for couplings for the transmission of power between the rotatin
33、g shafts of two machines in special-purpose applications in the petroleum, petrochemical and natural gas industries. Such applications are typically in large and/or high speed machines, in services that can be required to operate continuously for extended periods, are often unspared and are critical
34、 to the continued operation of the installation. By agreement, it can be used for other applications or services. Couplings covered by this International Standard are designed to accommodate parallel (or lateral) offset, angular misalignment and axial displacement of the shafts without imposing unac
35、ceptable mechanical loading on the coupled machines. It is applicable to gear, metallic flexible element, quill shaft and torsionally resilient type couplings. Torsional damping and resilient type couplings are detailed in Annex A; gear-type couplings are detailed in Annex B and quill shaft style co
36、uplings are detailed in Annex C. This International Standard covers the design, materials of construction, manufacturing quality, inspection and testing of special-purpose couplings. This International Standard does not define criteria for the selection of coupling types for specific applications. T
37、his International Standard is not applicable to other types of couplings, such as clutch, hydraulic, eddy-current, rigid, radial spline, chain and bellows types. 2 Normative references The following referenced documents are indispensable for the application of this document.
