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.
