Prevent the reduction of residual salt concentration by converting red rust in the main water supply pipe (distribution pipe) to black rust.

Prevent the reduction of residual salt concentration by converting red rust in the main water supply pipe (distribution pipe) to black rust.

The red rust prevention device "NMR Pipe Protector" converts red rust in water pipes to black rust and prevents the decrease of chlorine (residual chlorine) concentration for disinfection.

The NMR Pipe Protector has been widely adopted as a device for preventing red rust and extending the life of piping, and it has recently gained attention in the water distribution pipes of water supply authorities. At the Japan Water Works Association's water supply research presentation held in 2013, the Yokohama City Water Bureau published a paper presenting the results of a demonstration experiment showing that the use of this product can suppress the decrease in chlorine concentration in tap water. This matter was also reported as an article in the Japan Water Newspaper. The initial verification confirmed a decrease in iron ion levels in the water and an increase in residual chlorine concentration before and after installation in the water supply pipe of the public housing attached to the Tsurumi water supply reservoir. Next, a comparison of residual chlorine concentrations was conducted, revealing that before installation, the chlorine concentration was 0.5 PPM in the test pipe located 10 meters from the main pipe, 0.3 PPM at a distance of 60 meters, and 0.2 PPM at 135 meters, indicating that the residual chlorine concentration decreased with increasing distance due to red rust in the piping. After the installation of the NMR Pipe Protector, it was confirmed that the chlorine concentration at 135 meters doubled. From these test results, the effectiveness of suppressing the decrease in chlorine concentration was verified, demonstrating that the NMR Pipe Protector can also be used to prevent red rust deterioration in the main water supply pipes. *For more details, please refer to the PDF or contact us.*

To prevent pipe rust, a famous bookstore building has introduced NMR pipe protectors.

To prevent pipe rust, a famous bookstore building has introduced NMR pipe protectors.

The red rust prevention device "NMR Pipe Protector" prevents red rust deterioration in air conditioning pipes, ensuring long-term extension of the pipes and proactively preventing asbestos issues.

The building housing the famous bookstore in Shinjuku is always bustling with many people. About 20 years ago, we were troubled by the deterioration of the air conditioning chilled and hot water piping due to red rust. Because asbestos was used in the ceiling, it was practically impossible to carry out piping replacement work. As an alternative to piping replacement, we introduced the 'NMR Pipe Protector,' a device that can be installed on the outside of the piping to extend its lifespan by over 40 years. A pipe inspection, which involves removing a section of the piping for examination, was conducted 19 months after the installation of the NMR Pipe Protector. The results showed no signs of red rust corrosion on the inner surface of the piping, and the conversion of red rust to black rust was confirmed, indicating a very good condition of the piping. The building is already 57 years old, but the galvanized steel piping used for the air conditioning chilled and hot water system, which has been in use since its completion, has shown no leaks, and a follow-up survey in 2020 confirmed that there has been no occurrence of red rust since the installation of the NMR Pipe Protector. *For more details, please refer to the PDF document or feel free to contact us.*

Pipe rust prevention, Mansion Palace Tsurumi has introduced NMR pipe protectors.

Pipe rust prevention, Mansion Palace Tsurumi has introduced NMR pipe protectors.

Rust prevention device "NMR Pipe Protector" demonstrates rust prevention effectiveness even when introduced to a 39-year-old condominium!

The "Palace Tsurumi" condominium in Tsurumi Ward, Yokohama City, Kanagawa Prefecture, has introduced the red rust prevention device "NMR Pipe Protector" in its 39th year since construction. This is the first implementation of measures against red rust deterioration in the water supply pipes since the building was completed. The management company proposed updating the piping with stainless steel pipes as a measure against water supply pipe deterioration. However, due to the repayment of loans from exterior wall repair work and a shortage of reserve funds, it was difficult for the management association to proceed with the piping update. The management association approved the introduction of the NMR Pipe Protector at the general meeting because it came with a guarantee that "if it does not work, we will refund you." The red rust prevention device "NMR Pipe Protector" quantitatively measures its effectiveness to provide an objective evaluation of its rust prevention effects. As the red rust gradually transforms into black rust with a volume reduction of 1/10 due to the NMR Pipe Protector, the Palace Tsurumi conducted an endoscopic investigation of the red rust blockage rate at two locations in the seventh year after installation, showing a reduction in blockage rates of 35.3% and 17.4% compared to before installation. Even without maintenance of the piping for 39 years since completion, the NMR Pipe Protector demonstrated its rust prevention effectiveness. *For more details, please refer to the PDF or feel free to contact us.*

Pipe rust prevention, Legend Hotel Saigon introduces NMR pipe protectors.

Pipe rust prevention, Legend Hotel Saigon introduces NMR pipe protectors.

Terrible red water becomes clear! The "NMR Pipe Protector," a device that eliminates red water caused by red rust in pipes in a short period.

At the Legend Hotel Saigon (now Lotte Hotel Saigon) in Vietnam, severe red water emerged from the water supply pipes just six years after its construction. Despite running the water for an extended period, there was no sign of improvement, leading to a situation where guests could not even take a shower. The water in Vietnam contains a high level of sulfuric components, making it very prone to red rust formation when it reacts with galvanized steel pipes (SGP). In response, in 2008, a red rust prevention device called the "NMR Pipe Protector" was installed in the water supply piping. Before the installation, red water was coming from all the water faucets in the hotel. However, about a month and a half later, water quality checks in the sinks, baths, and toilets of ten guest rooms on the 14th to 17th floors showed that almost all the water supply had become clear, confirming the effectiveness of the red rust prevention. The corrosion of red rust in the water supply pipes was halted, and it was successfully transformed into black rust. This demonstrated that even in water with a high sulfuric content that easily corrodes water supply pipes, the red rust could be converted to black rust, exhibiting a high level of rust prevention effectiveness. *For more details, please refer to the PDF document or feel free to contact us.*

To prevent pipe rust, Tokyo University of Science has introduced the NMR Pipe Protector.

To prevent pipe rust, Tokyo University of Science has introduced the NMR Pipe Protector.

The red rust prevention device "NMR Pipe Protector" prevents the deterioration of piping due to red rust, resulting in significant cost savings.

The Kagurazaka campus of Tokyo University of Science was 26 years old at the time. The water supply pipes were made of PVC-lined steel pipes, and serious red rust blockages had occurred at the joints of the water supply pipes. Before the installation of the NMR Pipe Protector, an inspection of the red rust blockage rate in the toilet water supply piping revealed that the blockage rate was 35%, indicating significant red rust deterioration. After the introduction of the NMR Pipe Protector, a re-inspection was conducted at the same location 10 months later. The results showed that the red rust blockage rate had decreased to 31%, and it was verified that the red rust was gradually changing from a volume of 1/10 of black rust from the surface. At Tokyo University of Science, the NMR Pipe Protector was introduced to extend the lifespan of the piping in buildings and facilities that were originally scheduled for replacement in 10 to 15 years.

To prevent red rust in piping, Nihon University College of Engineering has introduced the NMR Pipe Protector.

To prevent red rust in piping, Nihon University College of Engineering has introduced the NMR Pipe Protector.

The red rust prevention device "NMR Pipe Protector" achieves rust prevention and strengthening of pipes through the black rust transformation of red rust! It significantly reduces maintenance costs for water supply pipes.

At the Nihon University College of Engineering campus in Koriyama City, Fukushima Prefecture, the water supply pipes in several research buildings were significantly deteriorated due to red rust, resulting in red water coming out of the taps on holidays and the following days. To reduce future piping renewal costs by 1/5 to 1/10, a red rust prevention device called the "NMR Pipe Protector" was installed. The results of an inspection conducted one month after installation clearly demonstrated the excellent performance of the NMR Pipe Protector. The iron content in the water due to red rust decreased to less than 1/10 of the pre-installation level (from 7.8 mg/L before installation to 0.1 mg/L after installation). Initially, the iron content was at 7.8 mg/L, exceeding the water quality standard value set by the Water Supply Act (0.3 mg/L), indicating a very serious progression of red rust. However, after installation, the levels were significantly below the standard, proving the rust prevention effect through the blackening of red rust and the extension of pipe life. The water quality was remarkably restored to a hygienically satisfactory level. The NMR Pipe Protector is an exceptionally effective rust prevention device that saves energy in creating new piping, thereby reducing environmental burden. *For more details, please refer to the PDF document or feel free to contact us.*
