LNG storage tank cold insulation materials
LNG storage tanks have a cold insulation material called perlite
The LNG storage tank is a storage tank specially used to store liquefied natural gas at -162°C. Most of the tank walls of this storage tank adopt a double-layer structure, and the inner wall is filled with cold insulation material to make it resistant to low temperatures of -162°C. Effect. The wall of the LNG storage tank has a cold insulation material called expanded perlite
Expanded perlite is a new type of industrial material. It is a white granular material with a honeycomb structure inside, which is made by perlite ore after preheating and instantaneous high-temperature roasting and expansion.
Expanded perlite is mainly used for the thermal insulation layer of storage tanks, which can avoid the brittle effect of low temperature on the outer and inner walls of storage tanks. Expanded perlite is used for thermal insulation and cold preservation, and also plays a role in filtration and adsorption to maintain the stability of LNG storage tanks. The cooling performance meets the design requirements.
