The main technical standards applicable to turbine compressors in the refining and petrochemical industry are as follows. It can be seen that the current product standards for turbine compressors are all industry standards. In terms of standard adoption, both SY/T 6651 and JB/T 6443 adopt (IDT) the American Petroleum Institute standard API 617-2002. SH/T 3144 adds some technical specifications on the basis of API 617-2002, and its scope of application is limited to centrifugal/axial flow compressors. The most significant difference between API 617-2002 and previous versions is the expansion of the range of materials applicable to this standard (to three types of equipment: axial/centrifugal compressors, integrated gear-driven centrifugal compressors, and expanders-compressors). The standard is structured into four sections: the first section covers general requirements, while the other three sections specify requirements for each of the three equipment types. In addition, API 617-2002 has raised the technical requirements in areas such as equipment design, manufacturing, and dynamics; for example, the continuous operating time of the equipment has been increased from 3 years to 5 years, and there is also more content related to rotor dynamics. JB/T 4359 was originally aligned with the standard ISO 8011-1988, and it applies only to axial flow compressors whose working medium is air. The provisions regarding material selection under special operating conditions, analysis of the rotor’s damped unbalanced response and stability analysis, as well as the standards for conducting performance tests, are somewhat simpler compared to the API 617 standard. When turbo compressors transport various process gases, shaft end seals must be used to prevent or limit the leakage of these gases into the atmosphere along the compressor’s rotating axis, thereby ensuring safe operation. Turbo compressors generally use sealing types such as labyrinth seals, floating ring seals, mechanical seals, and dry gas seals. Non-contact seals such as dry gas seals have become the preferred choice for shaft end sealing in environments with hazardous gases, thanks to their advantages including high reliability, no oil contamination, low power consumption, and long service life. Standard SY/T 6651 provides detailed specifications for various types of shaft end seals, along with typical structural cross-sectional diagrams. JB/T 11289 is applicable only to the dry gas seal type, but it covers both compressors and pumps as applications, and it provides relatively detailed regulations regarding seal design, manufacturing, inspection, and leakage standards. **Standard GB/T 25630-2010 is an equivalent adoption of the international standard ISO 5389-2005; it represents the standard procedure to be followed for the preparation, conduct, and evaluation of performance tests on turbine compressors. API 617-2002 also recognizes the provisions of ISO 5389 in the standards for compressor performance testing, but the preferred standard for such testing is still the American standard ASME PTC-10-1997. In fact, ISO 5389 is an international standard that combines the provisions of the American standard ASME PTC-10 and the German Engineers’ Association standard VDI 2045. It focuses on converting the measured values from test results into guaranteed values using similar theories, in order to determine the degree of reliability of those results. The industry standard JB/T 3165 and ASME PTC-10 are not based on each other as reference standards; although both standards classify test gases into two categories – contract-specified gases and substitute gases – ASME PTC-10 provides more detailed regulations regarding gas calculation formulas, recommended conversion models, and the treatment of inter-compressor stage cooling.
