摘要:: 双层金属结构低温储罐的安装工艺主要有正装法和倒装法。文章对比了两种施工工艺的优缺点，通过工程实例分析了施工成本，认为对于中小型双层金属结构低温储罐而言，倒装施工工艺优于正装工艺，并针对倒装施工工艺的施工难点提出了解决方案。
The installation technique for low temperature storage tank with double layer metal structure is mainly divided into normal assembly method and inverted assembly method. The merits and drawbacks of those two methods are compared and the installation costs are analyzed through engineering practices. It is considered that the inverted assembly method exceeds the normal assembly method for medium and small scale low temperature storage tanks with double layer structure. The scheme for overcoming construction difficulties of inverted assembly method is also presented in this paper.
