Low temperature pressure vessel
Design temperature of -20 ℃ below the pressure vessel: liquefied ethylene, liquefied natural gas, liquid nitrogen and liquid hydrogen storage and transport of containers are low temperature pressure vessels.
Design temperature of -20 ℃ below the pressure vessel: liquefied ethylene, liquefied natural gas, liquid nitrogen and liquid hydrogen storage and transport of containers are low temperature pressure vessels. General pressure vessels commonly used ferritic steel in the temperature down to a certain temperature, the toughness of the steel will drop sharply, and appear very brittle, usually called this temperature for the brittle transition temperature. Pressure vessels are used under conditions lower than the transformation temperature, such as the existence of defects in the container, residual stress, stress concentration and other factors caused by high local stress, the container may not appear in the case of obvious plastic deformation of brittle rupture and catastrophic accidents.
