Reliability-evaluation of earthquake-resistant capacity for large storage tank;

In this article,the discussion of several equations commonly used in calculating spherical arc plate of vault in large storage tank was carried out.

Taking the integral remove of a 2 000 m3 standing cylindrical storage tank with a dome at Xinjiang Kelamayi Petrochemical Company for example, this paper discusses the characteristics of two integral remove methods of large scale storage tank which are to use heavy catepillar and use rolling bars with jacks aided.

By the means of analysis on the calculation of shell thicknesses for large storage tanks,based on 50,000m~3 and 100,000m~3 sizes,by the method for calculating,allowable stress and joint efficiency factor etc.

Anti-seismic research is becoming increasingly important for large storage tanks.

The characteristic of the large tank is large diameter and very thin shell wall, so the large tank has ability of weak anti-deformation.

A device was designed for pressuring and fastening rigidly the welding test pieces,on which the load was put on the tank,by which the technology of the large-scale storage tanks was assembled by inverted construction method.

The safety state, regulations and codes inspection techniques for pressure pipeline and storage tank implementing in China are reviewed.

On the basis of construction experience and analysis on the features and deficiencies of the construction process of the floating roof, a novel single deck floating roof construction process for large-scale storage tank is summarized, which uses the method of CO2 shielded welding plus manual welding.
