The corrosion-inhibiting effect of 1, 4-Di (thiocyanatomethyl) benzene on iron in pH 2 geothermal brine was investigated through weight-loss measurement at 150°C and electrochemical measurement at 50°C. Pitting corrosion and whole-surface corrosion on the iron were inhibited by the 1, 4-Di (thiocyanatomethyl) benzene, which increased the cathodic polarization and showed an excellent inhibition effect on steel tubes in two-phase flow geothermal brine.
