"Underwater water delivery pipe WNG" can be constructed with a single long piece!
There are numerous achievements in water supply to remote islands and the intake of deep seawater. A composite structure polyethylene pipe with excellent corrosion resistance, pressure resistance, flexibility, long length, and earthquake resistance!
WNG is a composite structure polyethylene pipe that is excellent in corrosion resistance, pressure resistance, flexibility, long length, and seismic resistance, designed for transporting seawater and wastewater under conditions such as underwater water supply to remote islands, seawater intake, and underwater discharge. The installation work underwater can minimize the environmental impact on the marine environment by using an automatic burial machine. Nominal diameter: 40–250 【Features】 - The inner surface of the pipe and the outermost layer are made of polyethylene material, which is highly resistant to corrosion and salt damage, and has strong mechanical strength due to metal material reinforcement! - Since it can be manufactured and transported on-site in long lengths, joint connections on the seabed are unnecessary, allowing for reliable installation in a short construction period! - Compared to steel pipes, installation is significantly faster, and even when joints are necessary, the reliable fusion system provides peace of mind! - By utilizing an automatic burial machine equipped with an underwater water jet pump, installation at depths of around 100 meters is possible. - The polyethylene pipe has low friction resistance and minimal scale adhesion, so no time-dependent accumulation is necessary. In 2024, we carried out the replacement construction of the underwater water supply and drainage pipe from Atami City to Hatsushima. A total of 6,745 meters was constructed as a single piece without joints! The installation at a maximum depth of 103 meters is one of the deepest for underwater water supply and drainage pipes in Japan.
