1. Regarding the effectiveness of rust prevention (anti-corrosion) In the UK, coil-type electromagnetic devices are primarily used as a measure against calcium scale, and their effectiveness in preventing red rust has not been recognized. In fact, at St. Thomas' Hospital, famous for Florence Nightingale and where the NHS headquarters is located, this device was introduced into the hot water piping, but it showed no anti-corrosion effect, and red rust deterioration was progressing. As a result, an NMR pipe protector was installed in 2005. Before installation, the hot water contained a high concentration of iron ions, but after one month, the concentration significantly decreased, halting the progression of red rust deterioration and confirming a change to insoluble black rust. Although coil-type electromagnetic devices are also sold domestically, please be aware that their effectiveness against red rust has not been confirmed. 2. Regarding the effectiveness of calcium scale prevention Coil-type electromagnetic devices are also sold domestically as scale prevention devices, but in a major food factory where they were introduced, they failed to prevent scale adhesion within the pumps. As a result, a non-scaler was adopted, completely preventing adhesion. Disassembly and cleaning, which were previously required every few months, are no longer necessary. If you have not achieved results with coil-type devices, please consider introducing a non-scaler.

**Effects After Installing the Non-Scaler** - Acid cleaning twice a year is no longer necessary, maintaining productivity without line stoppages. - Significant reduction in cleaning and maintenance costs as well as labor expenses. - Contributes to the longevity of piping equipment. In our factory, we use groundwater as cooling water, which has caused calcium carbonate scale (hard crystals) to adhere to the piping on the secondary side of the pump, necessitating acid cleaning twice a year. During this acid cleaning process, the factory line had to be temporarily halted, leading to significant economic losses due to production stoppages. To address this issue, a "Non-Scaler" was installed on the secondary side of the pump piping. Before installation, as seen in the photos, thick white scale was heavily adhered inside the piping, making removal extremely difficult. However, six months after the installation of the Non-Scaler, there was almost no scale adhesion observed inside the piping, and the effects were clearly evident, allowing for substantial cost reductions. *For more details, please refer to the PDF document or feel free to contact us.*

**Effects After Installing the Non-Scaler** - Eliminated the decrease in flow rate caused by calcium crystals - Both flow rate and temperature remain stable even after 4 months - No need for disassembly cleaning, significantly reducing maintenance time and burden At our factory, we used groundwater containing a high level of calcium (180 mg/L), which made it easy for calcium scale to adhere inside the valves, frequently causing a decrease in flow rate. As a countermeasure, we introduced a coil electromagnet device two years ago, but there was hardly any observed effect in preventing scale. Therefore, we newly installed a "Non-Scaler," and clear improvement effects were confirmed. Before installation, due to the decrease in flow rate and the accompanying drop in temperature, we had to perform disassembly cleaning of the valve plates approximately every 4 months, which took about 36 hours each time. However, after the introduction of the Non-Scaler, even after 4 months, there were no issues with the decrease in flow rate or temperature, and disassembly cleaning of the valves became unnecessary. Current maintenance now only involves lightly tapping the outside with a rubber hammer to remove softened deposits, leading to a significant reduction in work time. *For more details, please refer to the PDF document or feel free to contact us.*

This property is a 29-year-old building that originally used galvanized steel pipes (SGP) for its plumbing at the time of completion, but over the years, it has been updated to use vinyl-lined steel pipes (VLP). However, due to the building's structure, the plumbing inside the framework remained galvanized steel pipes (SGP), which led to the occurrence of red water due to corrosion. To address the red water issue in the water supply pipes and to protect and extend the life of the plumbing, NMR Pipe Protectors were installed. The NMR Pipe Protector costs less than one-tenth of traditional plumbing renovation work and can rehabilitate the pipes by converting red rust into black rust without allowing it to flow out. In water quality tests conducted before the installation of the NMR Pipe Protector, the iron ion concentration was 0.3 mg/l. However, about five weeks after the installation of the NMR Pipe Protector, this concentration dropped to 0.01 mg/l, which is one-thirtieth of the original level, effectively resolving the red water issue. Additionally, an endoscopic examination revealed that the rate of blockage due to red rust in the pipes improved by more than 10% after one year and three months. These results confirm that the rust prevention effect of the NMR Pipe Protector and the rehabilitation effect of converting red rust to black rust continue to be effective.

This property is 11 years old, and the red rust blockage at the joint of the water supply pipe in the exclusive area had progressed to about 70%. To prevent further progression of the red rust blockage and to avoid future piping renewal work, we adopted the NMR pipe protector, which costs less than one-tenth of that. As a result of an endoscopic investigation, the red rust blockage rate in the toilet water supply pipe at the first joint before the installation of the NMR pipe protector was 69.8%. Twelve months after the installation of the NMR pipe protector, the red rust blockage rate was reduced to 60.6%, showing an improvement of 13.2%. The significant improvement in red rust blockage due to the volume contraction associated with the transformation of red rust to black rust has been demonstrated, confirming the effectiveness of the piping rehabilitation due to the transformation of red rust to black rust.

At Hotel Serve Shibuya, galvanized steel pipes (SGP) are used for the air conditioning chilled and hot water piping, and there was a concern about the deterioration due to red rust and leakage from the joints. As a countermeasure against red rust deterioration and leakage, a red rust prevention pipe longevity device called "NMR Pipe Protector" was installed. Before the installation of the NMR Pipe Protector, water samples were taken from the air conditioning chilled and hot water piping, revealing that the water was tinted light brown, with a total iron content of 5.8 mg/l, indicating significant red rust corrosion within the pipes. Two weeks after the installation of the NMR Pipe Protector, the total iron content in the water within the air conditioning chilled and hot water piping significantly decreased to 0.6 mg/l. In a water sample taken four weeks after the installation, the water was nearly transparent, with the total iron content further reduced to 0.5 mg/l. It was proven that new red rust was completely prevented within the air conditioning chilled and hot water piping, and the existing red rust had transformed into inert black rust. Going forward, if the use of the NMR Pipe Protector continues to prevent external corrosion at Hotel Serve Shibuya, all red rust in the air conditioning chilled and hot water piping will change to black rust, and it has been demonstrated that this piping can be extended to the lifespan of the building. Naturally, leakage has been completely prevented thereafter.

This property has been in existence for 30 years, and there has been significant red rust blockage at the water supply pipe joints. Therefore, the red rust prevention device "NMR Pipe Protector" was adopted. When measuring the red rust blockage in the water supply pipes of Room A and Room B, it was found that before the installation of the NMR Pipe Protector, Room A had a blockage rate of 43.2% and Room B had a rate of 50.9%. 【Red Rust Blockage Rate One Year After Installation】 Room A: 41.7% Room B: 50.6% 【Red Rust Blockage Rate Five Years After Installation】 Room A: 39.7% Room B: 49.8%, confirming a reduction improvement rate of 8.1% and 2.1% respectively compared to before installation. 【Red Rust Blockage Rate Ten Years After Installation】 Room A: decreased to 36.8% Room B: decreased to 37.5%, showing a significant reduction in red rust of 48% for Room A and 26.3% for Room B compared to before installation. From these results, it has been demonstrated that the installation of the NMR Pipe Protector has halted the progression of red rust deterioration in the pipes, and the existing red rust has been reduced to black rust with a volume of less than 1/10, proving the effectiveness of pipe rehabilitation and red rust prevention.

Moseley Hospital has two independent hot water systems: one connected to the storage tank and the other connected to the hot water header, with galvanized steel pipes used in the hot water piping. As a result, NMR pipe protectors were installed in the storage tank piping and the hot water header piping to prevent red rust corrosion and leaks in both hot water systems. Water samples were taken from the hot water piping at five locations, and the average iron content in the water was calculated. Before the installation of the NMR pipe protectors, the average value was 13.824 mg/l. After 15 weeks of installation, it decreased to 1.3882 mg/l; after 31 weeks, it further decreased to 0.4762 mg/l; and after 49 weeks, it reached 0.3428 mg/l, showing a significant reduction. This result demonstrated that the NMR pipe protectors prevented the formation of new red rust within the pipes and reduced existing red rust to black rust, which is insoluble in water and has a volume that is one-tenth of that of red rust. It has been proven that by continuing to install NMR pipe protectors, the hot water piping will transform 100% of the red rust within the pipes into black rust, thereby extending the lifespan of the building.

The hot water supply pipes used in Windsor Castle, owned by the British royal family and with a history of 900 years, utilize SGP pipes. To prevent red rust deterioration and extend the lifespan of the pipes, an NMR Pipe Protector was installed on January 24, 2007. Before the installation of the NMR Pipe Protector, the iron content in the water in Room 107 was 3.32 mg/l, but 42 days after installation, it dropped to 0.007 mg/l. Additionally, the average iron content from two other sampling locations was 4.255 mg/l before installation, but decreased to 0.0105 mg/l after installation. This is significantly lower than the drinking water quality standard set by the UK, which is 0.2 mg/l. As a result, it has been demonstrated that the NMR Pipe Protector effectively prevents the occurrence of new red rust within the pipes and transforms existing red rust into black rust, which does not dissolve in water. By continuing to use the NMR Pipe Protector, the hot water supply pipes have completely eliminated internal red rust deterioration and, by preventing external corrosion, have become usable for as long as the building remains standing.

A follow-up survey was conducted in a condominium in Fukuoka Prefecture, 16 years after the installation of the NMR pipe protector. Before installation, the joints of the water supply pipes in Rooms A and B were inspected with a fiberscope, revealing red rust blockage rates of 50.7% and 78.2%, respectively, indicating significant progression of red rust blockage and the need for early intervention. Consequently, the NMR pipe protector was installed in the water supply piping. One year after installation, a follow-up survey was conducted under the same conditions as before installation, and the red rust blockage rates for Rooms A and B were as follows: [One Year After Installation] Room A: 50.7% → 48% [5.3%] reduction improvement Room B: 78.2% → 74.1% [5.2%] reduction improvement [Sixteen Years After Installation] Room A: 50.7% → 41.2% [18.7%] reduction improvement Room B: 78.2% → 68.4% [12.5%] reduction improvement From the above reduction improvement rates in red rust blockage, it was demonstrated that the NMR pipe protector completely prevented the occurrence of new red rust and that the red rust blockage transformed into black rust with a volume reduction to one-tenth. Additionally, it was proven that as long as this condominium remains standing for another 20 or 30 years, pipe replacement will not be necessary.

Nineteen years after the installation of the NMR pipe protector, an inspection was conducted by the condominium management association of a 9-story, 110-unit building in Sapporo, Hokkaido, when the building was 32 years old. They commissioned an external investigation company to examine the condition of red rust deterioration at the water supply pipe joints. Ten locations were selected within the pipe space of the water supply pipes (pipe diameters 25A to 65A) from the 1st to the 9th floor, and a non-destructive inspection using X-rays was performed on the joint areas. The results of the X-ray inspection showed that out of the ten locations, eight had no signs of red rust deterioration at the pipe joints. The other two locations showed only slight traces of corrosion, which were estimated to have occurred before the installation of the NMR pipe protector. This demonstrated that the red rust deterioration of the water supply pipes in this condominium had been completely prevented. Although the NMR pipe protector cannot prevent corrosion on the outside of the pipes, slight external corrosion was observed. However, by preventing external corrosion with anti-rust coatings, both the exterior and interior can be preserved. *Images and inspection results are quoted from a report by a certain industrial inspection agency.

Are you aware? The lifespan of piping is said to be about 20 years. At first glance, piping is often overlooked because it is not visible from the outside, but like buildings, it continues to deteriorate over time. Furthermore, in recent years, the majority of equipment damage caused by earthquakes has been due to "piping within buildings," such as air conditioning systems. Sudden leaks caused by earthquakes can occur in multiple locations and result in significant damage... Once a leak occurs, it requires a large-scale construction cost for "piping replacement (piping renewal)." To prevent accidents before they happen, we recommend the NMR Pipe Protector! ★ Just by installing it on the outside of the piping, it extends the lifespan of the piping and strengthens the interior! ★ = Maximum Benefits = - The initial cost is less than one-tenth of that for piping renewal - Running costs and maintenance are "zero" - High safety that is also implemented in food factories and hospitals Please feel free to contact us first.

【Effects After Installation】 ■ Prevention of damage to the impeller of the cooling water pump due to calcium crystals ■ Prevention of calcium scale solidification and adhesion inside the pump ■ Reduction of line stoppage frequency from 1.2 times per month due to pump disassembly and cleaning, leading to increased productivity! Our factory was experiencing a situation where the line stopped every month (20 times/year) due to strong calcium scale adhering inside the pump, causing internal damage and requiring disassembly and cleaning. After the installation of the "Non-Scaler," there have been no line stoppages for over six months. Upon checking the scale condition inside the pump casing, it was found to be soft and in fine particle form, rather than forming strong calcium scale. By preventing damage to the pump caused by calcium scale, we have not only avoided line stoppages but also achieved significant reductions in maintenance costs. *For more details, please refer to the PDF document or feel free to contact us.

The heat exchanger at the chemical plant was subject to calcium scale buildup, necessitating disassembly, cleaning, and washing every five months. When scale accumulated on the heat exchanger, it reduced cooling efficiency and negatively impacted product quality. After installing a "non-scaler" following the cleaning of the heat exchanger, there was no calcium carbonate buildup on the hot water piping even after five months, resulting in maximum cooling effectiveness of the cooling water and maintaining the lowest defect rate for products. Additionally, the need to stop the plant every five months to scrape off calcium carbonate from the outside of the hot water piping was eliminated, leading to a reduction in product defect rates and an improvement in productivity. *For more details, please refer to the PDF document or feel free to contact us.*

• Piping Materials

Calcium scale inevitably adheres to the interior of hot water boilers and similar equipment. To reduce the adhesion of calcium scale, traditionally, ion exchange resins have been used to soften the water by removing calcium ions before producing hot water in the boiler. The residual calcium in the water crystallizes as insoluble calcium carbonate within the boiler and adheres to it. Traditionally, strong alkaline agents were added to the boiler to prevent the formation reaction of calcium carbonate. However, strong alkaline hot water is highly corrosive to metals, leading to corrosion and deterioration of the boiler itself, internal piping, and hot water piping, which shortens the lifespan of the boiler and connected piping systems to around 10 years. The calcium scale prevention device "Non-Scaler" reacts the calcium in the water with free carbon dioxide within the Non-Scaler, forcibly transforming it into fine particles of calcium carbonate that are dispersed and flow in the water. Once calcium carbonate is converted into fine particles, it remains unchanged even under the high temperature and pressure conditions inside the boiler, flowing in its particulate state. Additionally, the effects of corrosion and deterioration caused by strong alkaline agents are eliminated, making it possible to extend the lifespan of the boiler and hot water piping by more than double.

• Piping Materials

The cooling water used in open-type central air conditioning cooling towers has its calcium concentration rise to about 7 to 10 times that of the make-up water (source water) due to evaporation, resulting in the formation of hard calcium carbonate crystals on the surface of the cooling fins outside the cooling tower, which reduces cooling efficiency. The non-scaler, when installed in the make-up water piping, transforms dissolved calcium hydroxide in the water into calcium carbonate nanoparticles, dispersing them in the water and preventing calcium from solidifying and adhering to the cooling fins of the cooling tower. *For more details, please refer to the PDF document or feel free to contact us.*

"Red Rust Deterioration of Air Conditioning Chilled and Hot Water Piping" Air conditioning chilled and hot water piping that has been in use for over 25 years experiences the loss of the zinc coating on the inner surface of the steel pipes within 4 to 5 years. As the surface of the iron comes into contact with water, red rust deterioration occurs, leading to red rust blockage. At the same time, this red rust flows into copper fan coils, causing further blockage and reducing the efficiency of heating and cooling. Additionally, the accumulation of red rust within the heat source equipment shortens its lifespan. As the red rust deterioration progresses within the piping, the threads at the joints may break off, leading to water leaks during strong earthquakes. Since the air conditioning chilled and hot water system is centralized, updating the piping requires hotels and inns to suspend operations for more than six months, and the cost of piping replacement can be several hundred million to over a billion yen. The damages incurred from the suspension of operations are also significant, leading to a demand for the development of technologies that can extend the life of air conditioning piping without replacement.

Today, as the entire society is changing due to the novel coronavirus, one of the most affected industries is the hotel industry. With a decrease in guests, a lack of banquet orders, and restrictions on dining in restaurants, income has drastically fallen. When water leakage issues arise due to rust in the plumbing from the aging of the building, the cost of necessary plumbing updates for repairs becomes very high, forcing hotels to consider borrowing from banks or selling the property. The NMR Pipe Protector, a plumbing longevity device, can reduce that cost to less than one-tenth. Even if sold, the amount will be deducted by the plumbing update costs that will arise in the near future. Hotels that are over 30 years old cannot avoid this issue sooner or later. The only solution to this problem is to compress plumbing update costs to one-tenth to one-fifteenth, extend the plumbing lifespan by over 40 years, and eliminate the need for long-term closures (which require at least six months for air conditioning plumbing updates) through the introduction of the NMR Pipe Protector. By using the world's only rust prevention device, the "NMR Pipe Protector," which converts internal red rust to black rust, improves plumbing strength, and extends plumbing lifespan by over 40 years, plumbing update costs can be reduced by more than 90%.

• Other air conditioning equipment

Water supply pipes and chilled/hot water piping generally require replacement due to aging deterioration. In hospitals with over 25 years of operation, the chilled/hot water piping can experience red rust deterioration, leading to red rust blockage. At the same time, this red rust can flow into copper fan coils, causing blockages and reducing heating and cooling efficiency. Additionally, the red rust can accumulate within the heat source equipment, shortening its lifespan. In the water supply pipes, red rust can develop at the joints, and as the red rust deterioration progresses within both pipes, the threads at the joints can break off, leading to leaks during strong earthquakes. The NMR Pipe Protector prevents red rust deterioration, transforms red rust into black rust to improve pipe strength, and extends the lifespan of the piping. Since the chilled/hot water system is centralized, if piping replacement is carried out, the hospital must halt operations for more than six months, and the replacement costs can reach hundreds of millions to over a billion yen. The damages caused by operational downtime are also significant, leading to a demand for technology that can extend the lifespan of the air conditioning piping without replacement. The NMR Pipe Protector, a device for preventing red rust within pipes, has made this possible at less than one-tenth the cost.

Art museums, museums, cultural centers, libraries, and other places frequently visited by the general public and tourists use energy-efficient warm-type central air conditioning. The chilled water piping for this air conditioning is made of galvanized steel pipes (SGP pipes), which, after more than 20 years of construction, experience deterioration due to red rust. When the threads at the pipe joint deteriorate and fall off due to red rust, leaks can occur from these weakened areas during earthquakes or other events. Additionally, deterioration from red rust inside the pipes can lead to problems such as reduced heating and cooling efficiency and early failure of the heat source equipment. The solution to this issue of red rust deterioration inside the pipes is the pipe rehabilitation device NMR Pipe Protector.

At the Yokohama City Waterworks Bureau, a demonstration test was conducted at the 20-year-old Tsurumi water reservoir's attached public housing to prevent red rust from occurring in the water supply pipes, thereby solving the problem of reduced chlorine concentration in the water due to red rust. The test was carried out using the water supply pipe in the vacant bathroom of room 102. The piping materials used included polyethylene-lined steel pipes in the shared areas and resin pipes in the exclusive areas, where red rust was found to be occurring at the pipe joint sections. Before the installation of the NMR pipe protector, the iron concentration in the stagnant water at the bathtub water supply faucet during nighttime was 0.27 mg/L, with a residual chlorine level of 0.11 ppm at that time. Additionally, over the two weeks prior to installation (with water flowing for 3 hours a day), the amount of red rust accumulated on the faucet filter was 13 mg/L, indicating that corrosion due to red rust at the pipe joint sections was significantly advanced.

• Water treatment equipment

The Yokohama City Waterworks Bureau confirmed an increase in residual chlorine concentration to prevent red rust and the associated reduction of disinfectant chlorine in the water supply pipe at the Tsurumi public office. Therefore, starting from November 5, 2012, a demonstration test was conducted using the water distribution pipe (100A) in the Hazawa area to prevent the decrease in residual chlorine concentration. During six measurements conducted from September 26 to October 30, before the installation of the NMR pipe protector, the residual chlorine concentration at the planned installation site (Point A) averaged 0.55 mg/L (with Point A's residual chlorine concentration set at 100%), while 50 meters downstream (Point B) averaged 0.41 mg/L (a reduction rate of 25.45%), and at the farthest point, 125 meters away (Point C), it averaged 0.23 mg/L (a reduction rate of 58.18%), indicating a decrease due to the red rust occurring in the piping. Subsequently, on November 5, the NMR pipe protector was installed, and after more than three months, during three measurements from February 19 to March 22, the residual chlorine concentration at the installation site (Point A) averaged 0.61 mg/L, while at 50 meters downstream (Point B) the average for the same three measurements was 0.61 mg/L (a reduction rate of 0%), showing that the decrease was mostly prevented. Even at the farthest point, 125 meters away (Point C), the average for the same three measurements was 0.55 mg/L (a reduction rate of 9.84%), significantly improving the reduction rate.

At the Yokohama City Waterworks Bureau, based on the confirmation of the effectiveness of rust prevention and residual chlorine reduction at the Tsurumi public housing water supply pipe (first test) and the verification of residual chlorine reduction at the water distribution pipe (main water pipe) (second test), residential areas with a low number of water contracts and low water usage were selected. A test was conducted using a 50A water branch pipe in March 2016 to determine how little water usage is acceptable for the application of the NMR pipe protector. The areas chosen were Teramae 2-chome, which has a small number of households, and Konan Chuo area, where tests were conducted to evaluate the rust prevention effect and residual chlorine reduction effect of the NMR pipe protector. The guideline for demonstrating the rust prevention effect of the 50A piping is that approximately 15 tons of water usage per day is required for about 30 households. In contrast, in the Teramae 2-chome area, there were only 18 households downstream of the sampling location, while in the Konan Chuo area, there were only 3 households downstream of the sampling location. In both areas, the minimum water usage required for the NMR pipe protector to function effectively could not be secured, and therefore, its effects were not clearly observed. It was determined that the application of the NMR pipe protector was unsuitable for both the Teramae 2-chome and Konan Chuo areas, and the verification of the rust prevention effect of the NMR pipe protector, along with the associated residual chlorine reduction effect, was concluded as there were no suitable locations for the NMR pipe protector within the Yokohama City Waterworks Bureau other than these two areas.

This facility has been in operation for 22 years, and the corrosion within the pipes has progressed significantly, highlighting the need for pipe replacement due to leaks. However, it was impossible to carry out water outage work because it supplies chilled and hot water to four buildings, including commercial facilities within a large-scale complex. As a countermeasure, we installed the pipe rehabilitation device "NMR Pipe Protector." After installation, there have been no occurrences of leaks, and the results of regular mass analysis of the amount of black rust in the pipes have demonstrated that red rust is being prevented and pipe rehabilitation through black rust formation has been proven. The amount of black rust before the installation of the "NMR Pipe Protector" was 2.2%, which increased to 72.9% after 12 months and reached 91.7% after 45 months, proving the anti-corrosion effect within the pipes. If we continue to use the "NMR Pipe Protector" in the future, pipe replacement will not be necessary as long as external corrosion does not occur.

This factory has only been in operation for 8 years, but due to the influence of bacteria growing inside the pipes, the formation of red rust has progressed significantly, leading to frequent leaks, which required the pipes to be replaced each time. As a countermeasure, we installed the "NMR Pipe Protector." Since then, there have been no occurrences of leaks, and the analysis results of the amount of black rust showed that the percentage of black rust in the rust before installation was 1.9%, which increased to 66.9% after 14 months of installation, proving the blackening of red rust.

This factory has been in operation for 15 years, and there are significant concerns about corrosion within the piping. As a countermeasure, we installed the "NMR Pipe Protector." After installation, there have been no occurrences of leaks, and the mass spectrometry results of the black rust within the rust showed that the progression of red rust was prevented, confirming the rehabilitation of the piping due to black rust formation. The amount of black rust in the rust increased from 1.2% before installation to 76.8% after 12 months, and to 90.2% after 23 months, proving the black rust formation from red rust. If we continue to use the "NMR Pipe Protector," piping replacement will not be necessary as long as external corrosion does not occur.

Due to significant concerns about the corrosion of the cooling water piping, a "NMR Pipe Protector" was installed as a countermeasure when the facility was 43 years old. Analysis of the amount of black rust after installation demonstrated that the "NMR Pipe Protector" effectively prevents the progression of red rust and promotes the formation of black rust. The amount of black rust before installation was 2.0%, but it increased to 48.2% after 10 months of installation, confirming the reduction of red rust to black rust. If the "NMR Pipe Protector" continues to be used in the future, the piping will not need to be replaced as long as external corrosion does not occur.

Due to significant concerns about the corrosion of the hot spring water piping in this facility, an "NMR Pipe Protector" was installed as a countermeasure when the building was 38 years old. Analysis results of the amount of black rust after installation have demonstrated that the "NMR Pipe Protector" effectively prevents the progression of red rust and promotes the formation of black rust. The amount of black rust before installation was 0.9%, but it increased to 16.9% after 6 months of actual operation, proving the reduction of red rust to black rust. In the future, if all the red rust in this piping turns into black rust, piping replacement will not be necessary as long as external corrosion does not occur.

London City University, located in North London, is one of the famous universities in the city. It uses SGP for its air conditioning hot water piping, and the pipes in buildings over 40 years old were experiencing red rust corrosion. To completely protect the piping from red rust corrosion, NMR pipe protectors were installed. Before installation, the iron content in the water due to red rust was 3.407 mg/l, but two weeks after installation, the iron content decreased to 0.084 mg/l. This demonstrated that the NMR pipe protectors prevented the occurrence of new red rust in the pipes and reduced existing red rust to inert black rust. With the conversion of red rust to black rust, the piping was completely protected from red rust corrosion, allowing the air conditioning hot water piping to be usable for over 40 years. ▼ For more details, please see the related link ▼

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.

To demonstrate the rust prevention effect of the NMR pipe protector, a certain amount of water must flow through the piping. In the Konan Chuo area where the rust prevention effect test was conducted, the minimum water usage for a 50A pipe was 4.4 tons per day, but only three households were using that water, resulting in a total water usage of 1 ton per day (an average of 350 liters per day per household), which is very low. In the Teramachi 2-chome area, the number of households using water for each branched pipe with a diameter of 50A was six and eight, respectively, with the six households using about 2 tons of water per day and the eight households having a total water usage of just under 3 tons per day. Due to insufficient water usage, a clear rust prevention effect could not be confirmed. However, in the Tsurumi Public Housing and Hazawa area, where similar verification tests were conducted, the conditions were met. In Tsurumi Public Housing, the red rust in the water supply pipe decreased from 0.27 mg/l to 0.12 mg/l six weeks after the installation of the NMR pipe protector, and an increase in residual chlorine concentration, which had been reduced due to red rust, was confirmed. In the Hazawa area, the residual chlorine concentration, which had decreased by 45.3%, improved significantly to a reduction of 13.6%. The Yokohama City Waterworks Bureau has concluded the tests as there are no more suitable locations to further test the rust prevention effect of the NMR pipe protector.
