随着石油化工行业的发展,液化天然气(LNG)的需求逐步显现,由于天然气在零下162℃下可以液化,此时体积仅为气相的1/600,便于运输和储存,LNG储罐是目前世界各国正在大力发展的贮存和调峰手段。大型LNG低温储罐由于其规模化效益及便于集约化管理,在国家能源设施建设中具有重要的地位。大型低温储罐的需求量不断增加,对于其施工技术及施工管理的要求也就日趋严格。本文即是阐述罐顶组装施工技术的实际应用。
With the development of the petrochemical industry, the demand for liquefied natural gas (LNG) is gradually emerging. Since natural gas can liquefy at minus 162 ° C, the volume is only 1/600 of that of the gas phase, which is convenient for transportation and storage. The LNG storage tank is the world Countries are vigorously developing storage and peaking measures. Large-scale LNG cryogenic storage tank plays an important role in the construction of national energy facilities due to its large-scale efficiency and convenience of intensive management. Large-scale demand for low-temperature storage tanks continue to increase, for its construction technology and construction management requirements have become more stringent. This article is to explain the practical application of the construction technology of the tank top assembly.
