Content

When cryogenic liquids receive high heat from the surrounding environment or absorb a large amount of energy from the surrounding environment, their volume will expand due to rapid vaporization. At 0°C and 101.3KPa pressure, the gas volume after vaporization of 1L low-temperature liquid is: nitrogen is 674L, oxygen is 800L, and argon is 780L. In a closed container or pipeline, the internal pressure increases due to the vaporization of low-temperature liquid, which can easily cause the container or pipeline to explode due to overpressure.
