How to stop pipe being damaged corrosion? NMR Pipetector
NMR Pipetector effectively prevents red rust in steel water pipes in any buildings, including apartments, hotels and hospitals. The device extends the life expectancy of metallic pipes as long as that of buildings without replacing them. It is the most cost-efficient way to address red rust-relating issues in a short period without shutting off the water supply.
NMR Pipetector’s outer part is made of stainless steel. The inner part contains black body substances formed in a process of sintering 12 kinds of rare metals.

Place of installation
For apartment domestic tap water systems
We install NMR Pipetector on the outlet pipe of a water pump or an elevated tank.
A suitable place for the installation varies by system and building structure. Shown below is a selection of typical installation examples.
For heating and chilled water systems
We install NMR Pipetector on the outlet pipe of a water pump. If a system has more than one water line, NMR Pipetector is installed on the pipe that entirely covers the water pipe.
For condenser water systems
We install NMR Pipetector on the outlet pipe of a water pump.
For circulating domestic hot water systems
We install NMR Pipetector on the outlet pipe of a water pump. If there is more than one water line, NMR Pipetector is installed on the pipe where the entire water flows within.
*NMR Pipetector is basically suitable on pipes where water flows at a velocity fewer than two meters per second for maximum efficiency. For steel pipes where water runs faster than this, we install two NMR Pipetector in series. It also needs at least a 130 mm-straight pipe for actual installation works.

Reason１：Various case studies
Since our foundation in 1988, we have been handling NMR Pipetector as our main product for over 25 years. Thanks to the long-term support from our customers, we can keep our business growing. We strive to satisfy our customers even more, and that is why we can propose our products with confidence.
Adopted at more than 4,200 buildings
The number of successful installations we achieve is increasing every year. As of March 2020, the sum gratefully exceeded 4,200. Of the total, about 3,000 are apartments.
NMR Pipetector can be installed at any buildings, such as hospitals, hotels, universities, museums, department stores and various factories. There are five major piping systems NMR Pipetector is suitable: water mains, central heating and chilled, condenser, domestic tap, and hot water steel pipework.
NMR Pipetector is highly evaluated for its safeness and rust-preventing effect. It is introduced to many iconic buildings not only in Japan but also in overseas nations.
We received client testimonials from four buildings as shown above: the Royal Bank of Scotland, which highly evaluated NMR Pipetector’s rust-preventing effect a year after the installation, the Guildhall in Central London, Whittington Hospital managed by Whittington Health NHS Trust, and a five-star hotel the Royal Garden Hotel London.
Absolutely cheaper than the replacement of steel pipes
Replacement of steel pipes costs between 6 and 10 thousand US$ per family in an apartment. On the other hand, NMR Pipetector costs 1/5 to 1/10 than the replacement. In other words, the device can reduce costs by 80 to 90%.
Avoid unnecessary risks when shutting off the water supply
We ought to shut off the water supply to implement a replacement of steel piping, which costs a large amount of money. We need to suspend facility operation as the water supply has to be ceased during such works. This also leads to a large financial loss. It can be very profitable especially to hotels and hospitals by avoiding those works.
When it comes to NMR Pipetector, there is no need to do so. With the device, residents at apartments and condos do not need to line up every day for a portable bathroom during the replacement.
Zero maintenance and operation costs!
NMR Pipetector does not use any power supply, consumable parts or chemical drugs, so there is no operation cost whatsoever. Also, the product itself is maintenance-free throughout its minimum life expectancy of 40 years, which leads to a significant reduction of labor and cost.
Achieving greater building asset
With NMR Pipetector, buildings can save their budget for the maintenance of steel pipes. For example, an apartment can use a budget leeway to increase its asset value. Some of our customers actually used their extra budget to paint their exterior walls, waterproof their roofs, and even install an elevator.
NMR Pipetector had a tremendous effect on improving a long-term refurbishment plan at an apartment in Japan.

Total solution for red rust corrosion in steel pipes
Red rust adheres to the inner surface of steel pipes as the years pass by.
Red rust dissolves in water and has the chemical property of making iron corrode and crumble. This leads to several issues, such as water discoloration, clogging, water leak and pipe joint break.
Reduces red rust to black rust
With free electrons of water, hydrated electrons, NMR Pipetector converts internal red rust to another substance called black rust.
Difference between steel pipe rinsing and NMR Pipetector
As for steel pipe rinsing, a conventional and major method to address red rust, pipes are damaged and deteriorated when red rust is removed from within. Quite the opposite, NMR Pipetector improves red rust clogging inside steel pipes while strengthening pipes themselves by reducing red rust to black, not damaging the inner surface.
Extends lifespan of steel pipes to that of building
If each room has a daily water consumption at about 200 ~ 300 liters per day, NMR Pipetector’s effectiveness will last for more than 40 years. It means that the lifespan of your steel pipes is extended as long as that of the building’s. There are many cases where piping’s life expectancy actually extended for more than 40 ~ 50 years with NMR Pipetector.
Eliminates sliminess caused by bacteria
Steel pipe rinsing requires repeated cleaning once every 3 to 4 years to prevent bacteria from reoccurring. However, this hastens the steel pipe deterioration as the cleaning wears off pipe thickness. NMR Pipetector can permanently eliminate single-cell bacteria just by installing it on the outer surface of a pipe.
Chemical reaction in steel water pipes
Red rust occurs in steel pipes when they are oxidized with water and oxygen. This process can be expressed in a chemical formula as 4FeO + 3O2 + 2H2O → 4FeO (OH). At this time, iron is deprived of electrons through the oxidation process. In other words, iron oxidation stops when electrons are given to iron. With this reaction, NMR Pipetector reduces red rust to black rust by supplying hydrated electrons to red rust. This reaction is 6FeO (OH) + 2e– → 2Fe3O4 + 2H2O + 2OH–.
Hydrated electrons located inside general water molecules
Water is an aggregation of water molecules (H2O). These aggregations are called water clusters, which contain hydrated electrons.
Using hydrated electrons
NMR Pipetector generates certain electromagnetic waves that relocate hydrated electrons inside normal water clusters to their outer surface. The detail is this: when the specific electromagnetic waves are emitted to water molecules, their nuclei, which are polarized to the North and South poles like magnets, start to resonate and cause a rotation. This phenomenon is called nuclear magnetic resonance (NMR). With the NMR phenomenon and water flow in steel pipes, hydrated electrons are emitted throughout piping from the outer surface of smaller water clusters.

Innovative technology obviating chemical dosage
- Protects pumps from being damaged by calcium scale
- Improves the heat exchange efficiency
- Prevents the calcium scale adhesion
Our other device, Non-Scalor, works as follows: Non-Scalor oxidizes calcium elements (calcium hydroxide) in water to make them disperse into ultra-fine particles of calcium carbonate. This function prevents calcium scales from adhering to the inner surface of water pumps, boilers and other heat exchangers.
