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 the monthly magazine "Piping Technology," which is a specialty technical magazine for piping engineers, articles on the technology and achievements of the NMR Pipe Protector have been published. This magazine, established in 1959, provides technical information for plant engineers in industries such as oil, chemicals, power generation, and various manufacturing sectors. It is published by Nippon Industrial Publishing, a highly trusted publisher that mainly handles technical magazines in mechanical and electrical engineering, as well as architecture. Publication location: Pages 65 to 68 (4 pages) Media information: · Target readers: Equipment personnel from government agencies and local governments, university and various research institution staff, and responsible personnel and engineers in oil, chemicals, power generation (thermal, hydro, nuclear), pharmaceuticals, and various manufacturing sectors.

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 vinyl-lined steel pipe (abbreviated as VLP), which has a layer of PVC on the inside to prevent the iron from coming into direct contact with water, thereby preventing the occurrence of red rust. However, while there is no red rust formation in the straight sections of the pipe, red rust does 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 the cross-section of the pipes comes into contact with water. The joints where the pipes connect 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 loss of thread over time. After about 20 years, the number of remaining threads is reduced by about half. For more details, please see the related links below.

At Cosmo Kajigaya Le Seine, a pipe rehabilitation device called "NMR Pipe Protector" was installed in 2000, 14 years after its construction, to prevent red rust deterioration of the water supply pipes. In the 10th year after installation, an inspection was conducted, confirming the transformation of red rust to black rust 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 they remain in excellent condition.
