A novel evaluation technique, based on an artificial pit electrode, has been developed for inhibitor studies. The first example is of three generic inhibitors, against localised corrosion. The second is of three industrial inhibitors against existing localised corrosion on a north sea production platform
The study evaluated the effect of pH buffer on corrosion control of steel materials at elevated temperatures. Laboratory results of pH buffer in sodium chloride, potassium chloride, sodium bromide and sodium chloride/sodium bromide brines, Field case histories for buffered brine packer fluids in high-temperature, high-pressure wells.
Hydrogen Induced Cracking (HIC) can be a major issue for line pipe exposed to sour environments. In this study, influence of the test solutions on HIC evaluation was investigated from the view point of corrosion. Electrochemical measurements were employed to compare corrosion behavior of line pipe steels between the 0.93N acetate buffer solution and the conventional 0.05N acetate solution.
Biocides and corrosion inhibitors can decrease corrosion in stagnant and flowing systems. We used 1 ml syringe columns packed with 60 carbon steel beads (55 mg each), which were continuously injected with the effluent of an sulfur reducing bacteria continuous culture chemostat, to monitor corrosion under flow conditions.
