Extend the lifespan of piping! Case study of the "NMR Pipe Protector" introduced at Christ's College, Cambridge University.
Christ's College, Cambridge University, originated from God's House, which was established in 1437, and was rebuilt and opened as Christ's College in 1505 at nearly the same location. It is also famous for producing numerous notable alumni, including Charles Darwin, the author of "On the Origin of Species." The university's air conditioning hot water piping has been troubled by issues related to red rust internally, and although sacrificial anodes were introduced in 2008 as a countermeasure, the progression of red rust did not stop. Additionally, an anti-corrosion agent was applied annually, but there was no change in the iron content of the water before and after its use, raising concerns about the agent's impact on human health. Therefore, to remove red rust and single-celled bacteria while maintaining the strength of the piping, an NMR pipe protector was installed on July 31, 2013, in the air conditioning hot water piping (return pipe) of the Todd Building on the university campus. The iron content in the water, which was 43.81 mg/l before installation, dropped to 17.95 mg/l three weeks after installation. As October arrived and the air conditioning hot water system operated at full capacity, the levels continued to decrease, reaching 0.5195 mg/l by August 5, 2014, 52 weeks after installation, which is about one-eighty of the original level.
