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

The rust at the joint of the coupling, and the rust that forms between the vinyl coating and the base metal, what has happened to it 5 years after the installation of The Bio Water! Let me introduce it.

Here is the translation: We would like to introduce a case study of the Little Finger Heights Building J (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, allowing red rust to develop from that area. Furthermore, water can enter between the vinyl coating and the exposed metal, which can corrode the iron unnoticed and lead 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 formed on the exposed metal part of the joint, with a strong black rust layer beneath it. - Not only black rust, but also a calcium layer formed on top of it. - When the calcium layer is removed, the black rust beneath it is formed in a way that surrounds the exposed metal part of the joint, as if it were artificially welded. *For more details, please refer to the PDF document or feel free to contact us.
