SYSTEM FOR PREDICTING CORROSION OF PLURAL UNDERGROUND METAL TANKS

摘要

PURPOSE: A system for predicting corrosion of plural underground metal tanks is provided to predict the life span of the metal tanks and anodes by automatically controlling a rectifier, monitoring and analyzing anticorrosive potential, corrosive rate, and output current of the anodes in real time. CONSTITUTION: A system for predicting corrosion of plural underground metal tanks includes plural underground HSCI(Hi-Silicon Cast Iron,21-24) around the outline of plural oil tanks(11-14), plural underground sacrificial anodes(31-38) at the sides where the center part of a crowded area(10) contacts with the inner edges of the metal tanks, so that the outline of each metal tank becomes anti-corrosive by current(i1) provided from the HSCIs, and the other parts not applied with the current becomes anti-corrosive by current(i2) provided from the sacrificial anodes.
