Abstract: Mild steel is very important material for petroleum industry and it is used in several processing units like oil recovery, refining of crude oil, transportation, storage and petroleum products. Processing of crude oil is done in environment having strong acids and at high temperature, hence, rate of corrosion increases during this process. The corrosion inhibitors are used to reduce corrosion damage in sub-surface equipments in oil well field. In this study corrosion inhibition activity of four inhibitors namely 2-mercaptobenzoxazol, 2-mercaptobenzimidazol, N-cetylpyridiniumbromide and propargylbenzene-sulphonate was studied by gravimetric (viz. weight loss) and potentiostatic polarization methods in the temperature range of 30-70ÂșC in presence of 20% HCl.
