Systems such as pipes, heat exchangers, and storage tanks are often subject to hydrostatic testing after fabrication. Corrosion inhibitors may be added to the hydrostatic test solution to provide corrosion protection prior to the installation and use of these systems. Effectiveness of these corrosion inhibitors has been well documented and proven, however the parameters of the hydrostatic test and the effect of those parameters on the performance of the corrosion inhibitor performance are not well studied. This paper will assess a unique test method to simulate hydrostatic testing and the corrosion protection offered by a corrosion inhibitor. The effects of various hydrostatic test parameters on the performance of the corrosion inhibitor will also be studied.
