The effect of adjusting pH and adding inhibitor to prevent carbon steel from corrosion in the de-salting water, which is close to neutral, open to atmosphere at 50˚C, is studied through weight loss method, and the difference of anti-corrosion effect between the two methods is mainly studied. The test results show that the corrosion of carbon steel can be prevented by adjusting pH and adding imidazoline, and its corrosion can be prevented by adding imidazoline with a proper concentration for a long time, only can be prevented by adjusting pH for a short period of time.
