EN ISO 16812:2007 (E) 5 Introduction 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
26、purchaser from accepting, alternative equipment or engineering solutions for the individual application. This may be particularly applicable where there is innovative or developing technology. Where an alternative is offered, the vendor should identify any variations from this International Standard
27、 and provide details. Annex A provides some optional recommended practices. A bullet (z) at the beginning of a clause or subclause indicates a requirement for the purchaser to make a decision or provide information (see checklist in Annex B). In this International Standard, where practical, US Custo
28、mary (USC) units are included in parentheses for information. EN ISO 16812:2007 (E) 6 1 Scope This International Standard specifies requirements and gives recommendations for the mechanical design, material selection, fabrication, inspection, testing and preparation for shipment of shell-and-tube he
29、at exchangers for the petroleum, petrochemical and natural gas industries.
