A case where it was confirmed that the red rust inside the piping is in a good condition and not dissolving in water!
St. Ignatius Church, also known as the Catholic Kojimachi Church, is a historic church adjacent to Sophia University that has existed since before the war. Four years ago, due to the deterioration of red rust in the air conditioning chilled and hot water piping, we conducted an evaluation of the rust prevention effect of the "NMR Pipe Protector," a device designed to prevent red rust within the piping. Before the installation of the NMR Pipe Protector, we collected samples of the circulating chilled and hot water, which showed a brownish color. Water quality tests revealed a total iron concentration of 240 mg/l, indicating significant progression of red rust corrosion within the piping. After installing the NMR Pipe Protector, we conducted another water sampling test two weeks later, and the water color had become nearly transparent, with the total iron concentration due to red rust reduced to 2.7 mg/l, a substantial decrease. At the same time that the progression of red rust had stopped, the surface red rust within the chilled and hot water piping and the red rust in the water transformed into a non-soluble black rust, confirming the rust prevention effect of the NMR Pipe Protector within the chilled and hot water piping. This result was featured in an article published on July 18, 2018, in issue 2737 of "Air Conditioning Times," which reported on the verification of the rust prevention effect of the NMR Pipe Protector at St. Ignatius Church.
