• Water Treatment

Old pipes are likely to suddenly cause multiple leaks even with a small earthquake. Large-scale replacement work for the pipes can result in significant damage... What measures can be taken now?

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 happens, it requires a large-scale construction cost for "replacing the piping (piping renewal)." To prevent accidents before they happen, we recommend the NMR Pipe Protector! ★ By simply installing it on the outside of the piping, it extends the lifespan of the piping and strengthens the interior! ★ = Maximum Benefits = - The introduction cost is less than one-tenth of 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.

• Air conditioning

A condominium that used an NMR pipe protector to prevent red rust in the water supply pipes, reducing the piping renewal costs 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 the issue of red rust 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 to 90%. At "Cosmo Kajigaya Le Seine," the introduction of the NMR Pipe Protector created financial flexibility, and they began 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 together at an extraordinary general meeting, where it was 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 document or feel free to contact us.*

• Renovation and repair methods

The NMR pipe protector has been proven to not only prevent red rust in apartment water supply pipes but also to slow down the deterioration of red rust in drainage pipes, reducing the frequency of drainage pipe cleaning by 30%.

The red rust prevention device "NMR Pipe Protector" is an excellent product that reduces red rust to black rust and strengthens piping. Red rust has the property of generating red water and corroding pipes until they become deteriorated. Co-op Nomura Minami Ishikiri installed the NMR Pipe Protector in August 2001, marking its 24th year. After 15 years, a deterioration diagnosis survey of the piping was conducted. When the drainage pipes on the secondary side of the elevated water tank and inside the residences were inspected, it was found that there was almost no progression of red rust due to internal deterioration in both the water supply and drainage pipes. Thanks to the effect of the NMR Pipe Protector, red rust had hardly progressed, and its surface had turned to black rust, ensuring proper rehabilitation of the piping. Similarly, the drainage pipes showed almost no progression of red rust, earning high praise. *For more details, please refer to the PDF document or feel free to contact us.*

The management association of "Cosmo Kajigaya Le Seine" has verified the prevention of red rust deterioration in water supply pipes using the red rust prevention device "NMR Pipe Protector," ensuring long-term pipe longevity.

In the condominium "Cosmo Kajigaya Le Seine," which introduced the NMR Pipe Protector, polyvinyl chloride lined steel pipes (VLP) were used for the water supply piping. Polyvinyl chloride lined steel pipes (VLP) are pipes that are internally coated with polyvinyl chloride. The joint sections of the piping deteriorate due to red rust, but the straight sections are excellent in durability and corrosion resistance, and are currently used in most buildings' water supply pipes. However, this water supply piping has high maintenance costs, and after several decades of installation, measures against water leaks due to red rust at the joints are necessary. Many water supply pipes experience issues such as red rust blockage at the joint sections, water leaks, and deterioration of water quality after twenty years. The NMR Pipe Protector converts red rust into black rust, resolving these issues. Unlike pipe renewal work, the NMR Pipe Protector can be installed without water interruption, transforming the red rust inside the water supply pipes into black rust that strengthens the piping. By introducing the NMR Pipe Protector, red rust becomes inert black rust, extending the lifespan of the piping by over 40 years. *For more details, please refer to the PDF materials or feel free to contact us.

The red rust prevention device "NMR Pipe Protector" prevents red rust deterioration and leaks in the water supply pipes of apartments, reducing piping renewal costs to 1/5 to 1/10.

The costly part of large-scale repairs in condominiums is the "repair of the water supply piping." By introducing the red rust prevention device 'NMR Pipe Protector' into the water supply piping, it is possible to completely prevent the deterioration of red rust inside the pipes and extend the lifespan of the piping by over 40 years. This eliminates the need for costly piping replacement work during large-scale repairs of the condominium, significantly reducing the costs of such repairs. Additionally, the introduction does not require any water outage work, and it can be implemented at about one-fifth to one-tenth of the cost of updating the condominium's water supply piping, with no maintenance or running costs required afterward. For these reasons, by introducing this product, it is possible to save approximately 80-90% of the costs associated with large-scale repairs of the water supply piping. *For more details, please refer to the PDF document or feel free to contact us.
