Foreword
GB/T 7994-2014 "Test method for glass-lined equipment" is divided into two parts.
--- Part 1. pressure test;
--- Part 2. tightness test.
This section GB/T 17994-2014 part of.
This section drafted in accordance with GB/T 1.1-2009 given rules.
This Part replaces GB/T 7994-2005 "Test method for glass-lined pressure equipment", compared with the GB/T 7994-2005, Technical
Changes are as follows.
--- Glass-lined pressure equipment in accordance with the scope of the design pressure, select test gauge accuracy class;
--- Cancel the provisions of the text value of the test pressure;
--- According TSGR0004 "Safety Technology Supervision of Stationary Pressure Vessels," the provisions of the testing process step-up, step down into the
Line revision;
--- Increase the water pressure test may be a combination of gas and liquid pressure test method instead of the provisions, as Appendix A.
This part is proposed by the China Petroleum and Chemical Industry Association.
The glass-lined equipment in part by the National Standardization Technical Committee (SAC/TC72) centralized.
