Verification of the effectiveness of NMR pipe protectors by the Yokohama City Waterworks Bureau.
Confirmed the rust prevention effect inside the piping in areas where the NMR pipe protector's rust prevention effect conditions are met.
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.

Our article has been published on the electronic publishing platform "MEDIUM"!
An article from our company has been published on the electronic publishing platform "Medium"! Excerpt from "Everything You Need to Know About the Red Rust Prevention Device 'NMR Pipe Protector'" 1) Common water supply pipes in buildings such as apartments deteriorate over time due to red rust, making the red rust prevention device "NMR Pipe Protector" necessary. All buildings, including apartments, hospitals, hotels, and schools, have plumbing for baths, sinks, kitchens, and laundry. The piping material is generally a steel pipe with a vinyl lining (abbreviated as VLP), which has a layer of polyvinyl chloride on the inside, preventing the iron from coming into direct contact with water and thus preventing the occurrence of red rust. However, while there is no red rust in the straight sections of the pipes, red rust can occur at the joints between pipes, at the connections with copper alloy valves, and at the elbow joints made of copper alloy used to bend the pipes at right angles, as these areas come into contact with water. The joints where the piping connects with various components are fastened with screws, and since the threads are on the iron side, they gradually deteriorate due to red rust, leading to a reduction in the number of remaining threads by about half after approximately 20 years.

The content of an interview with our company conducted by students was featured in the "Intour" program!
The largest corporate interview community in Japan, "Intetour," has featured interview content conducted by students with our company. Two students, one in their second year at Rikkyo University and another in their fourth year at Doshisha University, interviewed our representative director and president. The site also introduces the appeal of our company as perceived by the students. Excerpt from a comment by a second-year student at Rikkyo University: "About the appeal of the company" Today, we spoke with Japan System Planning Co., Ltd. One of the company's appeals is that, unlike other companies, it focuses on means to achieve its objectives rather than on profit. In particular, they are engaged in activities that consider energy and environmental creation, specializing in the piping maintenance business with their "NMR Pipe Protector." They mentioned that their corporate activities are a form of social contribution. Additionally, they believe that individuals who understand and seek to utilize their own strengths are well-suited for the company.
