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.

Leakage prevention measures for the air conditioning piping at Hotel #M.

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

At Hotel #M, 21 years after its construction, the galvanized steel pipes (SGP) for the air conditioning chilled and hot water system were experiencing significant red rust deterioration, with a risk of leakage at the pipe joints. Therefore, a red rust prevention pipe longevity device called the "NMR Pipe Protector" was installed. Before the installation of the NMR Pipe Protector, a sample of the circulating air conditioning chilled and hot water was taken from the hotel’s piping, revealing that the water was brown due to red rust in the pipes, with a total iron concentration of 28 mg/l, indicating severe red rust corrosion within the piping. Two weeks after the installation of the NMR Pipe Protector, a water sample taken under the same conditions showed that the water color had become slightly transparent, and the total iron concentration had significantly decreased to 4.0 mg/l. A water sample taken six weeks after installation showed that the water color had become almost transparent, with the total iron concentration further reduced to 1.6 mg/l, proving that the progression of red rust within the pipes had completely stopped, and the existing red rust had transformed into an inert black rust that does not dissolve in water, with a volume reduced to one-tenth. At Hotel #M, it has been verified that if the use of the NMR Pipe Protector continues, all red rust in the air conditioning chilled and hot water pipes will change to black rust, and the costs will be less than one-fifth of the pipe replacement work, allowing the pipes to be extended for the lifespan of the building. Naturally, leakage has been completely prevented thereafter.

Leakage prevention measures for the air conditioning piping at Hotel #T.

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

At Hotel #T, when it was 29 years old, the red rust deterioration in the galvanized steel pipes (SGP) used for air conditioning chilled and hot water piping was very advanced, and leaks were occurring at the joints. Therefore, a red rust prevention piping longevity device called the "NMR Pipe Protector" was installed. Before the installation of the NMR Pipe Protector, a sample of the chilled and hot water circulating in the pipes was taken, and the color of the water was brownish due to the red rust inside the pipes, with a total iron content of 29 mg/l, indicating that the red rust corrosion in the pipes was very advanced. Two weeks after the installation of the NMR Pipe Protector, a water sample taken under the same conditions showed that the water was clear, and the total iron content had significantly decreased to 0.2 mg/l. Additionally, a water sample taken four weeks after installation under the same conditions also showed a total iron content of 0.2 mg/l, confirming that the red rust deterioration had been completely prevented, and the red rust inside the pipes had transformed into black rust, which does not dissolve in water and has a volume one-tenth that of the red rust. At Hotel #T, it has been verified that if the use of the NMR Pipe Protector continues, all red rust in the air conditioning chilled and hot water pipes will change to black rust, and the cost will be less than one-fifth of the cost of pipe replacement work, allowing the pipes to be extended for the lifespan of the building. Naturally, leaks have been completely prevented thereafter.

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.

Measures to prevent red water and leaks in the water supply piping of the Legend Hotel Saigon.

Case study on the introduction of NMR pipe protectors for preventing red rust and extending the lifespan of hotel water supply piping.

The Legend Hotel Saigon is a building that is 7 years old and used galvanized steel pipes (SGP) for its water supply piping. Due to the high sulfur content in the water supplied from Ho Chi Minh City, red rust corrosion in the hotel's water supply pipes progressed very quickly, resulting in red water coming from the faucets in guest rooms within 6 to 7 years after completion. There were also concerns about potential future leaks. To address the red water issue caused by red rust in the water supply pipes, a plan for pipe replacement was considered; however, it was costly and required a water outage, which would necessitate halting hotel operations. As a solution, the "NMR Pipe Protector," a device for rust prevention and extending the life of pipes that does not require a water outage, was installed by a major Japanese general contractor. Before the installation of the NMR Pipe Protector, very dark red water due to red rust was coming from the faucets, but 1.5 months after its installation, the water became almost clear, resolving complaints from the hotel. The NMR Pipe Protector has been proven to stop the progression of new red rust and convert the existing red rust in the pipes into inert black rust that does not dissolve in water.

Leakage prevention measures for the air conditioning piping at Hotel #P.

Case study on the introduction of NMR pipe protectors for preventing red rust and extending the lifespan of hotel air conditioning piping.

At a certain hotel, when it was 40 years old, the deterioration of red rust in the air conditioning chilled and hot water piping made of galvanized steel pipes (SGP) was very advanced, and leaks were occurring at the joints. Therefore, a red rust prevention piping longevity device called "NMR Pipe Protector" was installed. Before the installation of the NMR Pipe Protector, the amount of black rust in the red rust within the hotel's air conditioning chilled and hot water piping was 5.7%. However, six weeks after installation, the amount of black rust increased to 70.8%, demonstrating a relative increase of 1242.1%, proving that the red rust occurring in the air conditioning chilled and hot water piping was reduced to black rust. If the use of the NMR Pipe Protector continues in the future, all red rust in the air conditioning chilled and hot water piping will be reduced to inert black rust with a volume of 1/10, and as long as external corrosion does not occur, leaks from the air conditioning chilled and hot water piping will be prevented, extending the lifespan of the building. Naturally, the replacement of the air conditioning chilled and hot water piping will no longer be necessary.

Leakage prevention measures for the hot water supply piping at Hotel Toyokaku.

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

Hotel Toyokankaku is a 42-year-old building, and due to the use of galvanized steel pipes (SGP) for the hot water supply piping, issues such as leaks occurred, leading to frequent partial updates of the piping. However, there was still a serious issue with red water in the hot water supply piping in the guest room bathrooms, so we installed the rust prevention piping longevity device "NMR Pipe Protector." Before the installation of the NMR Pipe Protector, the iron ion concentration in the circulating hot water was high at 4.3 mg/l, but four weeks after installation, the iron ion concentration in the hot water significantly decreased to 1.6 mg/l, and further decreased to 0.27 mg/l eight weeks after installation, completely eliminating the red water. From these results, it was demonstrated that the NMR Pipe Protector converted the red rust in the hot water piping to black rust, preventing the red rust from dissolving into the water and reducing the iron content in the hot water. It was proven that external corrosion was prevented, leaks were avoided by continuing to use the NMR Pipe Protector, and the hot water piping was extended to the lifespan of the building.

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.
