Resolving the red rust and leakage issues in the water supply and hot water piping at the Marriott Hotel in the UK.

Case studies of introducing NMR pipe protectors for preventing red rust and extending the lifespan of hotel water supply and hot water piping.

The Bournemouth Highcliff Marriott Hotel, part of the world's largest five-star hotel chain, the Marriott Group, was built in 1878 and has 160 rooms. Due to the use of galvanized steel pipes for the hot water and water supply plumbing in the Marriott Hotel, very high iron levels were detected: 6 mg/l from the hot water plumbing and 3.46 mg/l from the water supply plumbing before the installation of the NMR pipe protector. The deterioration of red rust in the pipes was serious, including the presence of red water, raising concerns about future leaks. To eliminate the red water from the water supply and hot water plumbing, prevent red rust deterioration, and extend the life of the pipes, NMR pipe protectors were installed in both the water supply and hot water plumbing. Thirteen days after installation, the hot water and water supply (nighttime stagnant water) samples taken first thing in the morning were both clear, and the iron levels in the water had dropped to 0.007 mg/l, completely eliminating the red water. The reduction in iron levels prevented the formation of new red rust, and it was proven that the existing red rust in the pipes had transformed into a non-soluble volume of 1/10 of inert black rust. As a result, the formation of new red rust in the pipes was prevented, and the transformation of existing red rust into black rust demonstrated the effectiveness of the NMR pipe protector in preventing red rust and extending the life of the plumbing.

basic information

By continuing to use the NMR pipe protector, the hot water and water supply pipes have all turned from red rust to black rust, resulting in pipes that do not deteriorate from red rust on the inside. If external corrosion is prevented, the pipes will be extended in lifespan as long as the building exists. ■■■■■ Japan System Planning Co., Ltd. ■■■■■ Toll-Free Number: 0120-320-390 <Free Material Request / Inquiries> https://www.jspkk.co.jp/jp/contact/
