Defects inspection system for tank floors based on virtual instrument technique;

According to the current problems existing in the magnetic flux leakage testing for tank floor,a mobile robot was developed which could take the place of manual or power-driven approach to tank floor MFL inspection.

In order to improve the efficiency of magnetic flux leakage(MFL) testing for tank floors,the flaw location,test data description and visualization from anomalistic signals are studied.

Based on the magnetic flux leakage(MFL) technique,a magnetic flux leakage testing instrument for corrosion in the tank floor plate driven by electric motor is developed.

According to the basic principle of the experimental modal analysis,the strain modal of the vertical steel crude oil storage tank model with doom roof were tested.

In recent years, as the human demands of energy sources is growing up, much of ports and oil refineries set up a large amount of crude oil storage tanks, reliable operation of these facilities has direct relationship to the efficient production and the environment safety.
