Challenge
The customer had procured two spare boiler tube bundles and faced a serious challenge in preventing the progress of corrosion during the outdoor storage of these bundles. The tube bundles measure 1.5 meter in diameter and 4.5 meter long. The customer wanted a long term preservation solution that could withstand the harsh outdoor storage conditions and keep the bundles ready for use at any time.
Application
The boiler tube bundles external and internal surfaces were first dusted and cleared of any hard material, loose rust, and surface contamination using pressurized air. Then VpCI®-423 rust remover gel was brush-applied on the external surface of the tubes as well as the internals and externals of the drum side. The product was let sit for about 30 minutes and then pressure washed with VpCI®-415 diluted at 10% in water. This process was repeated 2 times until a satisfactory level of rust removal had been achieved. The internal and external surfaces of the tubes and drum were sprayed with VpCI®- 377 using an air paint sprayer. The internals of the tubes were then sprayed using VpCI®-337 and capped. The tube bundles were left to dry and wrapped with MilCorr® VpCI® Shrink Film.
Conclusion
Customer was surprised by the efficiency of Cortec® rust removal and preservation technology; and completed the preservation job satisfactorily.
