We exhibited at the Kansai Mansion Comprehensive EXPO 2023!

Extend the life of your current water pipes and air conditioning pipes for over 40 years! By converting red rust to black rust, we can rehabilitate the pipes and eliminate the need for expensive pipe replacements.

■Features - Cumulative installation record of over 4,400 buildings as of July 2025 - Extends the lifespan of water pipes for over 40 years, until the building's lifespan - Installation costs are about 1/5 to 1/10 of pipe renewal construction - Patented in Japan and the United States, registered in the Ministry of Land, Infrastructure, Transport and Tourism's NETIS new technology utilization system - No need for water outages, no running costs (electricity or chemicals) - Installed on the outside of pipes, allowing for short-term installation and ensuring hygiene - Comes with a product warranty ■Product Overview By converting red rust that occurs inside old pipes into black rust, we improve and strengthen the pipes, rehabilitating them. It also prevents the new occurrence of red rust. Red rust deteriorates pipes, while black rust has completely different properties. Black rust is smaller in volume, more robust, and insoluble in water, which strengthens the pipes and extends their lifespan by over 40 years. Typically, the lifespan of pipes is shorter than that of buildings (around 20 years), but it can be extended to match the building's lifespan without expensive pipe renewal. ■ Japan System Planning Co., Ltd. ■ Toll-Free Number: 0120-320-390 Official Website: https://www.jspkk.co.jp/jp/contact/

Replace everything when it gets old? You’ll regret it if you don’t know! A gentle management method for piping and the reasons behind it. New anti-corrosion technology for piping!

<Aren't you misrecognizing something?> - There won't be any red water, so it's fine, right... - If it's VLP pipes or anti-corrosion cores, there won't be rust, so it's okay... - For now, we're cleaning the pipes, so it should be fine... - If they get old, we'll just have to replace everything, right... = Knowledge is definitely beneficial = - Examples of red rust problems caused by pipes seen in images - What is "black rust" that completely solves the red rust issue? - The chemical change "reduction" that converts red rust to black rust - Pipe-friendly management methods and the reasons behind them *You can download the materials for free. *Please feel free to contact us first.

• Water treatment equipment

We have published numerous costs for when you actually implement it. We will provide a "cost comparison table" that clearly shows the comparison with the costs of updating piping!

~For those who are troubled by such issues~ ■ I don't have the money to rebuild or update the plumbing... ■ I want to quickly address the red water and plumbing clogs... ■ Water outage construction is quite a hassle... ★ Please download and view the PDF materials for the 'Case Studies' below. ★ Feel free to contact us if you want to know a rough estimate of the costs!

• Piping Materials

Incredible... Over 4,300 installations! Old piping can be kept without replacement thanks to rust prevention effects! We will introduce various case studies from different buildings all at once.

～Recommended for those who:～ ■ Want to continue using old piping ■ Do not want to cut or grind the piping ■ Prefer to avoid water outage construction ■ Do not want to spend much time or money...! The introduction cost is less than 1/5 to 1/10 of the cost of piping renewal! *Please download the PDF materials below to view the "Case Studies." *Feel free to contact us if you would like to know a rough estimate!

A condominium that used an NMR pipe protector to prevent red rust in water supply pipes, reducing the cost of pipe renewal to one-tenth, and used the remaining funds to install a new elevator.

The "NMR Pipe Protector" is a groundbreaking device for apartments and hospitals struggling with red rust issues in their piping, and it has received great acclaim. The introduction cost of the NMR Pipe Protector is about 1/5 to 1/10 of the cost of pipe replacement, allowing for a cost reduction of approximately 80-90%. At "Cosmo Kajigaya Le Seine," the introduction of the NMR Pipe Protector has created financial leeway, and they have begun considering the installation of a new elevator, which was a frequent request from residents. It was deemed financially feasible, and a proposal for the installation of the NMR Pipe Protector along with the new elevator was presented at an extraordinary general meeting and approved. Thus, the introduction of the NMR Pipe Protector brings various benefits to each facility. In addition to its effects on maintaining and improving water quality, it also makes a significant contribution in terms of cost. *For more details, please refer to the PDF materials or feel free to contact us.*

The installation of the rust prevention device "NMR Pipe Protector" on the water supply pipes has been confirmed through long-term verification that the black rust transformation of red rust inside the pipes progresses every year, improving the condition of the piping.

The "Lions Mansion Koshigaya North" in Koshigaya City, Saitama Prefecture, introduced the NMR Pipe Protector in November 2010, successfully reducing the cost of pipe maintenance to one-third of the amount originally planned for lining work in the long-term repair plan. Before the installation of the NMR Pipe Protector, and one year, five years, and ten years after installation, the rate of red rust blockage at the dissimilar metal joints, where red rust deterioration progresses the most, was continuously inspected, confirming that the rate of red rust blockage decreased over time. This indicates that the red rust is gradually transforming into black rust, which is one-tenth of its original volume. This has proven that the water supply pipes can be extended to the lifespan of the building. The management association effectively utilized the saved budget for projects such as converting lighting fixtures to LED. In addition to the LED conversion of lighting, the renewal of elevators is also being considered in the future. As a result, the NMR Pipe Protector has become a savior for the condominium. It has significantly reduced the costs of pipe maintenance, allowing the surplus budget to be allocated to other building facilities. **Results of the NMR Pipe Protector:** - No growth of red rust was observed in the endoscopic survey conducted six years after installation. - A reduction in the volume of red rust was noted, indicating that the transformation to black rust is progressing.

Recently, fine bubbles, which are tiny bubbles smaller than 100 μm and are referred to as "fine bubbles," have attracted attention in various fields such as the environment, agriculture, food, fisheries, and medicine, due to their ability to impart various functions to liquids. Fine bubbles are classified into two types based on their size: microbubbles and ultrafine bubbles. Recently, there has been a growing interest in ultrafine bubbles, which have a lifespan of several weeks to months. However, listening to the voices of researchers and users reveals some skepticism, which has become one of the issues hindering the spread of fine bubble technology. On the other hand, we have challenged the elucidation of the stabilization mechanism of ultrafine bubbles from a new perspective by enabling the control of number density exceeding 10 billion particles/mL without pressure or concentration operations using our ultrafine bubble generation technology. In this seminar, we will provide a fundamental explanation of fine bubble technology, including the basic physical properties, characteristics and functions, device technology, measurement and evaluation methods, and case studies, to promote research and utilization of fine bubbles based on a correct understanding.

Sekiguchi Iron Works Co., Ltd. will exhibit at the "Minami-Shinshu Environmental Messe 2025" held at S-Bird in Iida City, Nagano Prefecture. This exhibition will be held simultaneously with the "Environmental Industry Trade Fair" taking place the day before. It will be held over the weekend, with many family-friendly events planned. We encourage those who usually find it difficult to visit to take this opportunity to come. Our product exhibition area is located about 10 minutes from the venue. We sincerely look forward to your visit.
