Foreword
GB/T 28574 "petroleum, petrochemical and natural gas industries 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 rule according to GB/T 1.1-2009 given draft.
This standard uses redrafted law revision adopted ISO 10437.2003 "Petroleum, petrochemical and natural gas industries special purpose steam turbine."
This standard and ISO 10437. compared to 2003 in the structure added three informative appendix (Appendix A, Appendix B, Appendix C).
This standard and ISO 10437.2003 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 A. specific adjustments
as follows.
● with GB 3836 (all parts) in place of IEC 60079 (all parts);
