In recent years, with the rapid development of gas industry and natural gas industry, with liquid oxygen, liquid nitrogen, liquid ethylene and LNG for low temperature storage tanks are used more and more widely in the media. In addition to stop supporting large and large cryogenic storage tanks of large LNG device and LNG receiver, air separation device, small and medium sized LNG device, LNG storage and distribution station and LNG gasification station in the general configuration of small cryogenic storage tanks, tank capacity more than 10000m3 below. Low temperature storage tanks as the core equipment of this type of equipment, the choice of type of relationship between the cost of the entire device and the operating costs, the choice of the type of low temperature storage tanks to meet the requirements of the device is particularly important. Including the low-temperature tank type existing small and medium scale land use: general station device and vacuum powder insulated storage tank, composite cryogenic tank, cryogenic tank, spherical cylindrical flat bottomed vertical cryogenic storage tank.
