Foreword

GB/T 28574 "Petroleum, petrochemical and natural gas industries - Steam Turbine special purpose" and GB/T 28573 "Petroleum, petrochemical and natural gas workers General purpose turbine industry "together constitute the petroleum, petrochemical and natural gas industries steam turbine product standards. This standard GB/T 1.1-2009 given rule drafting. This standard uses redrafted Law Amendment uses APIStd611.1997 "Petroleum, petrochemical and natural gas industries in general purpose steam turbine." This standard APIStd611.1997 compared to the structure have more adjustment, listed in Appendix A of this standard and APIStd611. 1997 reg number control list. This standard APIStd611.1997 technical differences are as follows. --- Situation on normative references, this standard to make appropriate adjustments to suit our technical conditions, reflected in the adjustment of the focus Chapter 2, "Normative references", the degree of consistency between the documents and international instruments Appendix B. Specific adjustments as follows. ● with the GB/T 8117 (all parts) instead of the IEC 60953 (all parts); ● with the GB/T 17241 (all parts) instead of ISO 7005-2. --- In addition to the provisions of the normative references have been involved in the technical difference through its outer margin with a single vertical line (│) into The line marked. Appendix C gives the list of the corresponding technical differences and their causes. This standard also made the following editorial changes. --- Consistent with the series of standards, and in accordance with rules for preparation of GB/T 1.1, the standard name from "petroleum, petrochemical and natural gas industries a Turbine general purpose "to" petroleum, petrochemical and natural gas industries in general purpose steam turbine ", the English name from" General-Pur- poseSteamTurbinesforPetroleum, chemicalandGasIndustryServices "to" Petroleum, petrochemicalandnaturalgasindustriessteamturbines-General-purposeapplications "; --- The "Scope" in Chapter 1 was changed to the "scope" of the 1.1 "Use", 1.2 "flexible design", "inconsistent and 1.3 of Provisions "in accordance with the preparation of standard format, change the terms of numbers (see Chapter Article number Chart); --- 1.1.1 on the formulation of general purpose steam turbine, the words "terms and definitions" of 3.1, the expression special purpose steam turbine, See GB/T 28574-2012 "Petroleum, petrochemical and natural gas industries - Steam Turbine special purpose" in 3.41; Defined in the GB/T 28574-2012 provisions of this standard will not be repeated; --- Fixed some errors in the original text (see footnote 2 to footnote 7); --- Delete standard "US customary units" data, formulas and tables. The quality of the symbol by the "W" to "m", will speed symbol By the number "N" to "n"; --- All Imperial units are converted to metric units; --- According to Appendix D "Unless otherwise noted, all are pressure gauge," saying, delete the text and in the appendix table showing the pressure (g); --- According to GB/T 1.1-2009 provisions of the original Appendix order rearranged. The standard proposed by China Electrical Equipment Industrial Association. This standard by the National Standardization Technical Committee turbine (SAC/TC172) centralized. This standard is drafted by. Hangzhou Steam Turbine Co., Ltd. Participated in the drafting of this standard. Shanghai Power Equipment Research Institute. The main drafters of this standard.
