近年来,我国LNG产业已进入规模化发展阶段。随着低温技术的日益成熟,LNG作为应用领域的源头,与之配套的储存设备就显得尤为重要。而粉末堆积绝热的双层球罐以其节约材料、占地面积小、日蒸发率以及建造成本低等优点越来越受到人们的青睐。本文着重介绍了LNG双层球罐的设计、制造及检验等方面的内容。 In recent years, China’s LNG industry has entered a stage of large-scale development. With the development of cryogenic technology, LNG, as the source of application fields, is becoming more and more important with its storage facilities. The powder-packed double-layer insulated spherical tank with its advantages of saving material, small footprint, daily evaporation rate and low construction cost are more and more people’s favor. This article focuses on the LNG double-layer spherical tank design, manufacture and testing aspects.
