Abstract

During the technical diagnosis of vertical steel tanks it is necessary to evaluate the influence of geometry imperfection on deflected mode and resource. One of the most significant characteristics of geometry, definable during the full-scale tank diagnosis, is deflections of tank generatrices from the vertical. In the report, the tank geometry research results are represented on the basis of measuring data of 98 oil transporting system tanks

Highlights

The existing tank battery in a system of oil transportation is considerably depreciating
As vertical steel tanks are elements of complicated technical systems of extraction, transportation, and storage of oil and oil products, reliability assurance and estimation of safe working service of functional tanks is connected with lifetime improvement of tank battery and all the system of pipeline transport
Analyzing the distribution curves of the values of generatrix deviations, we can conclude the following: 1. The value of generatrix deviations grows with an increase in height and decrease in the plate thickness of the shell, and this quantity is mostly distributed over a sinusoidal curve

Summary

Introduction

The existing tank battery in a system of oil transportation is considerably depreciating. The scope of repair, reconstruction, and construction of new storage tanks It predetermined the increase of scope of technical diagnosis of vertical steel tanks (VST) with attraction of new technical means and methods. The existing system of technical diagnostics reflects modern requirements not to the full [1,2,3,4,5,6,7,8] In these conditions, it is necessary to take measures increasing the effectiveness of tanks usage by means of extension their safe working service in the process of production [9,10,11,12,13]. The consequence of reliability enhancement is safety of main funds
