[NMR Pipe Protector Verification Results] Hospital #I

Verification of rust reduction in chilled water of air conditioning systems for anti-corrosion effectiveness! Case study on measures to prevent leaks and extend the lifespan of air conditioning piping!

At Hospital #I, due to the significant deterioration of red rust in the air conditioning chilled and hot water piping, which uses galvanized steel pipes (SGP) that are 19 years old, we installed a red rust prevention piping extension device called "NMR Pipe Protector" to prevent leaks. Before the installation of this product, we sampled the circulating air conditioning chilled and hot water, and found that the total iron content in the water was very high at 5.1 mg/l due to red rust, indicating that corrosion from red rust in the piping was quite advanced. Three weeks after the installation, a sample of the air conditioning chilled and hot water showed that the total iron content in the water had decreased to less than 0.03 mg/l, completely halting the progression of new red rust in the air conditioning chilled and hot water. It was demonstrated that the red rust that had been present in the piping had transformed into insoluble black rust, which is 1/10th the volume of the original. If Hospital #I continues to use this product, the air conditioning chilled and hot water piping will no longer require updates in the future, and costs will be reduced to less than 1/10th, extending the lifespan of the building. *For more details, please refer to the PDF document or feel free to contact us.
