GB/T 7994.2-2014 "Test methods for glass-lined equipment—Part 2: Gas tightness test" specifies the requirements, methods, and the water/gas combined test method for the gas tightness test of glass-lined pressure equipment, applicable to various types of glass-lined pressure equipment. The test involves introducing gas into the equipment at a specified pressure, maintaining the pressure, and detecting pressure changes or external leaks to assess the sealing performance of the equipment. The detection requires the use of precision pressure gauges, gas pressurization devices, and leak detectors, ensuring the safe operation of the equipment under gas medium conditions.
