立式拱顶油罐吸瘪修复的理论分析与实践

The Theoretical Analysis on the Repair of Absorption of Vertical Type Vault Roof Tank and Its Practice

文章介绍了注水压气法修复立式拱顶油罐吸瘪的方法,从理论上分析了油罐修复的最大内压及安全试验压力,提出了防止油罐翘底的方法、计算,以及修复油罐的工艺技术、组织实施等程序,并在实践中取得了效果。

The article introduces the method of water filling and air compressing to repair the absorption of vertical type vault roof tank. It theoretically analyses the maximum internal pressure of tank repair and the safty testing pressure. The paper puts forward the method and the calculation which prevent tank bottem from wraping,and those procedures of processing technology and organized application for tank repair,etc. Thus,a good result has been achieved in the practice.
