Corrosion and inhibition tests were conducted on Oil Country Tubular Goods (OCTGs) in HCl and HCl/HF stimulation acid solutions at 65°C.Commercial inhibitors effectively inhibited L-80 and 13Cr steels. 22Cr duplex steel, however, was not inhibited satisfactorily, especially at low HCl/HF concentrations. The form of corrosion of 22Cr was selective attack. At low HCl/HF concentrations, corrosion product was formed on 22Cr surfaces and inhibitors were considered to be interfered by this corrosion product.To inhibit 22Cr, and to mitigate selective attack, high dosage of inhibitor was required. Another way of corrosion control was attained by the increase in HCl concentration. The increase in HCl concentration made the corrosion reaction more active and reduced the tendency to form the corrosion product, and resulted in the activation of inhibitors for 22Cr in stimulation acid solutions.
