[Magnetite Pipe Method Case Study] Kosodate Heights Building J (Tokorozawa City, Saitama Prefecture)

I will introduce how the rust at the joint of the coupling and the rust that forms between the vinyl coating and the base metal has changed five years after the installation of The Bio Water!

Here is the translation: We would like to introduce a case study of the "Shoshin Finger Heights Building J" located in Tokorozawa City, Saitama Prefecture. After investigating methods to prevent deterioration of the water supply pipes 20 years after construction, we installed The Bio Water following a year-long field test. The type of water supply pipe in this building is "internally coated lined steel pipe." This type of pipe is protected by a vinyl coating on the inside, but the ends of the pipes where they connect are exposed, leading to the progression of red rust from that area. Additionally, water can enter between the vinyl coating and the exposed metal, causing corrosion of the iron without notice, which eventually leads to leaks. We will introduce what happened to the two types of rust—"rust at the joint connection" and "rust that forms between the vinyl coating and the exposed metal"—five years after the installation of The Bio Water. [Five Years After The Bio Water Installation] ■ Rust at the Joint Connection - A white calcium layer has formed on the exposed metal part of the joint, with a strong black rust layer underneath. - Not only is there black rust, but a calcium layer has also formed on top of it. - When the calcium layer is removed, the black rust underneath appears to have formed around the exposed metal of the joint as if it were artificially welded. *For more details, please refer to the PDF document or feel free to contact us.
