Hotel and inn air conditioning piping is protected from red rust and leaks by NMR pipe protectors.

An article about the NMR Pipe Protector has been published in the piping specialty technical magazine "Piping Technology." In the June issue of "Monthly Piping Technology," a technical article on the NMR Pipe Protector, including its technology and achievements, has been featured. This magazine serves as a technical information source for plant engineers in fields such as petroleum, chemicals, power generation, and various manufacturing, and has a history dating back to its founding in 1959. It is published by Nippon Industrial Publishers, a highly trusted publisher that primarily handles technical magazines in mechanical and electrical engineering, architecture, and more. Publication location: Pages 65 to 68 (4 pages) Media information: - Target audience: Equipment personnel from government agencies and local governments, university and research institution staff, and responsible individuals and engineers in the fields of petroleum, chemicals, power generation (thermal, hydro, nuclear), pharmaceuticals, and various manufacturing.

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.

In Cosmo Kajigaya Le Seine, in 2000, 14 years after its construction, a piping rehabilitation device called "NMR Pipe Protector" was installed to prevent the deterioration of the water supply pipes due to red rust. After conducting a pipe inspection in the 10th year after installation, it was confirmed that the transformation of red rust to black rust had occurred and that the progression of red rust deterioration had completely stopped. Now, 20 years after the installation of the NMR Pipe Protector, and 34 years after construction, there are no issues with red rust in the water supply pipes, and the condition remains excellent.
