Pipe rust prevention, the BBC in the UK has introduced the NMR pipe protector.

Preventing red rust in the air conditioning pipes of the BBC in the UK, extending the life of the pipes by preventing leaks with the red rust prevention device 'NMR Pipe Protector'

The air conditioning piping in the main block building of the BBC (British Broadcasting Corporation) is 53 years old and has been experiencing leaks due to red rust deterioration. To avoid disruptions in program production during the pipe replacement work, a red rust prevention device called the "NMR Pipe Protector" was installed. The effectiveness of the NMR Pipe Protector in preventing red rust was verified in just about one month. Before installation, the iron content in the circulating water of the cooling water piping in the main block building was very high at 5.53 mg/L, indicating serious red rust deterioration. However, a water quality test conducted 32 days after the installation of the NMR Pipe Protector showed a significant reduction to 0.05 mg/L, which is less than 1/100 of the previous value, confirming the rust prevention effect due to the black rust formation caused by the NMR Pipe Protector. In the Stage 5 building, the iron content was also very high at 3.80 mg/L before the installation of the NMR Pipe Protector, but after installation, it decreased to approximately 0.06 mg/L, which is about 1/63 of the previous value, completely preventing red rust deterioration in the cooling water piping. Even in the 53-year-old BBC building, the high effectiveness of red rust prevention has been proven to prevent leaks and extend the life of the piping. *For more details, please refer to the PDF document or feel free to contact us.*
