■Patent obtained, NETIS Plus registration achievements. ■Introduced on World Business Satellite (WBS)! ■Short-term resolution of pipe blockages. ■No power required, no running costs. ■No chemicals used, safe for food factories. ■No maintenance required. The "NMR Pipe Protector" can resolve pipe blockages by converting red rust that has formed inside the pipes into black rust, revitalizing the pipes. Black rust has a smaller volume than red rust, is insoluble in water, and possesses strong properties. By converting red rust in the pipes to black rust, the original lifespan of approximately 20 years can be extended to over 40 years.

In a food processing factory that is 11 years old, a large amount of chlorine was used to suppress the growth of slime caused by bacteria in the cooling tower. To reduce the amount of chlorine being used, an "NMR Pipe Protector" was installed. Even with the chlorine input reduced to one-third, the growth of algae in the cooling tower was effectively suppressed. Additionally, the number of general bacteria (contaminants) decreased from 640 to 270, and the turbidity value, which increases due to organic matter contamination, was significantly reduced from 8 degrees to 3 degrees, within the water quality standards. [Introduction Overview] ■ Location: Shizuoka Prefecture ■ Building Overview: 11 years old, factory ■ Water Supply Method: Pump pressurization method ■ Installation Date: October 30, 1998 ■ Installed Piping/Number of Installations: Well water pump primary side (HI-VP 40mm)/PT-50DS x 1 unit *For more details, please refer to the PDF document or feel free to contact us.

In August 1998, an "NMR Pipe Protector" was installed in the cooling water circulation piping of the welding robot cooling line located within a major automobile manufacturer’s factory in Fukuoka Prefecture to prevent red rust scale. Before installation, red rust from the cooling water piping would leach out, entering the narrow cooling tubes of the body welding robots, causing blockages that resulted in the welding robots stopping, which took over 15 minutes to recover. Nine months after installation, the cooling water piping was inspected, and the amount of black rust compared to the red rust before installation increased significantly from 4% to 43.6%. Additionally, line stoppages were completely prevented. [Challenges] ■ Red rust leaching from the internal cooling water piping ■ Entry into the narrow cooling tubes of the body welding robots, causing blockages ■ Recovery from welding robot stoppages taking over 15 minutes ■ Damage costs exceeding 6 million yen per incident *For more details, please refer to the PDF document or feel free to contact us.

In this property, galvanized steel pipes (SGP) are used for the water supply piping, and at 35 years old, the pipes were diagnosed to have a lifespan of only 2 months due to frequent leaks and the occurrence of red water. To prevent red rust and extend the life of the pipes, an "NMR Pipe Protector" was installed. In the water quality test before installation, the iron content was 0.5 mg/l, and there was a significant occurrence of red water. However, six days after installation, the iron content dropped to below 0.05 mg/l, and the red water was completely resolved. Subsequently, water quality tests conducted 14 years and 20 years after installation showed that red rust had completely disappeared, and new leaks were entirely prevented, proving the rehabilitation of the piping. [Effects After Installation] ■ Water quality test six days after installation showed iron content below 0.05 mg/l, and red water was completely resolved. ■ Water quality tests 14 years and 20 years after installation showed that red rust had completely disappeared. ■ New leaks were entirely prevented, proving the rehabilitation of the piping. ■ Pipes with a statutory useful life of 15 years were extended by 40 years, maintaining a condition free from red rust deterioration until 55 years old. *For more details, please refer to the PDF materials or feel free to contact us.
