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

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.
