EN ISO 10441:2007 (E) 5 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 In

27、ternational Standard. Users of this International Standard should be aware that 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 enginee

28、ring solutions for the individual application. This may be particularly appropriate 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 require

29、s the purchaser to specify certain details and features. A bullet () at the beginning 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 whic

30、h are included as Annex J; otherwise it should be stated in the quotation request or in the order. EN ISO 10441:2007 (E) 6 1 Scope This International Standard specifies the requirements for couplings for the transmission of power between the rotating shafts of two machines in special-purpose applica

31、tions 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 to the continued operation of the installation. By

32、 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 unacceptable mechanical loading on the coupled machines

33、. 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 couplings are detailed in Annex C. This International

34、 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. This International Standard is not applicable to oth

35、er 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.
