Prediction of Soleplate Corrosion in Petroleum Storage Tank Based on Grey Model GM(1,1)

摘要

The corrosion protection of petroleum storage tank is important for safety work in petroleum depot. Precise prediction of soleplate corrosion may reflect the security state of a storage tank, and it can provide scientific references to the anti-corrosion and maintenance in safety management. Grey Model GM(1,1) in the Grey Theory, which is programmed by MATLAB, is introduced and applied to predict the soleplate corrosion of No.G-2 petroleum storage tank in Luquan oil depot. Compared with the measurements, the prediction results meet them very well, which shows that this model is practical, fast, and convenient. Meanwhile, it can reflect the status and the corrosion rate of a petroleum tank. Therefore, it is suitable for wide applications in other relative fields.
