Water supply pipe rust and leak prevention measures for a certain hotel #HO.

Case study of introducing NMR pipe protectors into hotel water supply piping.

At a certain hotel, #HO, significant red rust corrosion had progressed in the vinyl-lined steel water supply pipes after 25 years of construction, raising concerns about leaks from the joints. Therefore, a rust prevention and pipe longevity device called the "NMR Pipe Protector" was installed. Before the installation of the NMR Pipe Protector, a white filter was attached to the water supply faucet, and after running water for five days, the filter turned brown due to the red rust generated inside the water supply pipes, revealing that the iron content captured was 11 mg/l, indicating that the red rust corrosion in the pipes was quite advanced. One month after the installation of the NMR Pipe Protector, a white filter was attached at the same location and under the same conditions as before installation, and the captured iron content significantly decreased to 1.3 mg/l. This proved that the red rust inside the pipes had transformed into black rust, which does not dissolve in water. If the NMR Pipe Protector continues to be used, it has been verified that all red rust in the pipes will change to black rust, and the cost will be less than one-fifth of the pipe replacement work, allowing the pipes to be extended for the lifespan of the building. Naturally, leaks will also be completely prevented.

Certain hotel #RF water supply piping red rust and leak prevention measures

Case study of introducing NMR pipe protectors for preventing red rust and extending the lifespan of hotel hot water piping.

At Hotel #RF, which was built 38 years ago, significant red rust corrosion had progressed in the vinyl-lined steel water supply pipes, leading to leaks from the joints. Therefore, the red rust prevention and pipe longevity device "NMR Pipe Protector" was installed. Before the installation of the NMR Pipe Protector, a white filter was attached to the water supply faucet, and after running water for four days, the filter turned brown due to the red rust present in the water supply pipes, revealing that the iron content captured was 40 mg/l, indicating that the red rust corrosion in the pipes was quite advanced. One month after the installation of the NMR Pipe Protector, a white filter was attached at the same location and under the same conditions as before, and the captured iron content decreased to 23 mg/l. After six months of installation, the iron content further decreased to 14 mg/l, and the red rust in the pipes transformed into black rust that does not dissolve in water, demonstrating the rust prevention effect and longevity of the hot water supply pipes. It has been verified that if Hotel #RF continues to use the NMR Pipe Protector, all the red rust in the chilled and hot water supply pipes will change to black rust, allowing for pipe longevity at less than one-fifth the cost of pipe replacement work, extending the pipes' lifespan to that of the building. Naturally, leaks have been completely prevented since then.

Holiday Inn London, measures to prevent red rust and water leakage in air conditioning piping.

Case study of the introduction of NMR pipe protectors in hotel air conditioning piping.

The Holiday Inn London Heathrow, built in the 1970s, is one of the largest hotels in the UK with a total of 617 rooms, located near Heathrow International Airport. The hotel faced serious leakage issues throughout its air conditioning piping due to extensive red rust corrosion, resulting in numerous holes in the pipes and water flooding in guest rooms and hallways. To address this, a red rust prevention extension device called the "NMR Pipe Protector" was installed on February 12, 2008. Seven days after the installation of the NMR Pipe Protector, the iron content in the chilled water of the air conditioning system, caused by red rust, significantly decreased from 0.669 mg/l before installation to 0.017 mg/l, confirming the rust prevention effect of the NMR Pipe Protector. One year after installation, the iron content in the chilled water dropped to nearly zero at 0.007 mg/l, completely eliminating new leaks, and the red rust in the air conditioning piping transformed to almost 100% black rust, proving that the piping could be extended in lifespan until the building's end of life.

Measures for preventing red rust and water leakage in the hot water supply piping of a certain hotel.

Case study of introducing NMR pipe protectors for preventing red rust and extending the lifespan of hotel hot water piping.

At a certain hotel, #IP, the hot water supply piping made of heat-resistant vinyl-lined steel pipes had significant red rust corrosion after 31 years of construction, raising concerns about leaks from the joints. Therefore, a red rust prevention and piping extension device called "NMR Pipe Protector" was installed. Before the installation of the NMR Pipe Protector, a white filter was attached to the hot water faucet, and after running water for six days, the filter turned brown due to red rust generated in the hot water piping, revealing that the captured iron content was 150 mg/l, indicating that red rust corrosion in the piping was quite advanced. One month after the installation of the NMR Pipe Protector, a white filter was attached at the same location and under the same conditions as before, and the captured iron content decreased to 140 mg/l. Two months after installation, the iron content due to red rust further decreased to 17 mg/l, and the red rust in the piping transformed into black rust that does not dissolve in water, demonstrating the rust prevention effect and extension of the hot water piping's lifespan. At hotel #IP, it was verified that if the use of the NMR Pipe Protector continues, all red rust in the air conditioning chilled water piping will change to black rust, and the cost will be less than one-fifth of the piping replacement work, allowing the piping to be extended until the building's lifespan. Naturally, leaks have been completely prevented thereafter.

Royal Garden Hotel, UK - Measures for preventing red rust and water leaks in air conditioning and hot water piping.

Case studies of introducing NMR pipe protectors for preventing red rust and extending the lifespan of hotel air conditioning and hot water piping.

The Royal Garden Hotel London, famous as a five-star hotel in London, was built in 1965 and currently has 400 rooms. Due to the iron pipes in the hotel's hot water circulation system, red water was coming out of the taps every morning. To prevent rust and leaks in the piping and to extend its lifespan, an NMR Pipe Protector was installed. Before the installation of the NMR Pipe Protector, the iron content value due to red rust in the hot water supply during nighttime was very high at 2.79 mg/l. However, 25 days after the installation of the NMR Pipe Protector, it decreased to 0.016 mg/l, and further decreased to 0.013 mg/l 36 days after installation, falling below the water quality standard value of 0.2 mg/l set by the UK Water Supply Act. This reduction was achieved as the existing red rust in the pipes was converted into black rust, which is an insoluble form with a volume 1/10 of the original, thereby demonstrating the anti-corrosion effect and lifespan extension of the air conditioning and hot water piping.
