ABSTRACT
Corrosion behaviors of oil pipe steel P1 10 were investigated in multicomponent thermal fluid t 40 °C~280 °C by weight-loss method with autoclave, and corrosion inhibition of four high temperature inhibitors were evaluated under different temperature. The results show that there are two maximum for he corrosion rates of steel P1 10 at the testing temperature, 60 °C and 180 °C respectively. Corrosion inhibitors HGY-710 and HGY-701A are suitable for the corrosion protection demand of multicomponent thermal fluid; the protection efficiency is higher than 85% with 200 mg/L dosage. The protection effect or oil pipe is very well with 750 mg/L inhibitor HGY-710 in thermal exploitation production.
