低温绝热钢瓶又称低温液体钢瓶、焊接绝热钢瓶,用于贮存液氧、液氮、液氩等低温液体,能连续提供气态和液态存储介质,是一种新型移动式低温液体容器。低温绝热钢瓶与传统的气瓶气体贮存方式相比,有贮运效率高、运行成本低、使用方便、劳动者劳动强度低等优点。而且液氧使用成本比气态氧便宜近一半,因此低温绝热钢瓶在机械加工、医药、化工、卫生等领域得到广泛应用。
Low-temperature insulated cylinders, also known as cryogenic liquid steel bottles, welded adiabatic cylinders, are used to store liquid cryogenic liquids such as liquid oxygen, liquid nitrogen, liquid argon and the like, and are capable of continuously providing gaseous and liquid storage media. They are a new type of mobile cryogenic liquid container. Compared with the traditional gas cylinder gas storage method, the low temperature insulated cylinder has the advantages of high storage and transportation efficiency, low operation cost, convenient use and low labor intensity of workers. And the cost of using liquid oxygen is nearly half cheaper than that of gaseous oxygen, so cryogenic heat-insulated cylinders are widely used in machining, medicine, chemical industry and public health.
