"Underwater water delivery pipe WEETS" can be installed 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!

WEETS is a composite structure polyethylene pipe that is excellent in corrosion resistance, pressure resistance, flexibility, long length, and seismic resistance, designed for transporting seawater for underwater water supply to remote islands, seawater intake, and underwater discharge under seabed rolling and burial conditions. The installation work underwater can minimize the environmental impact on the underwater environment by using an automatic burial machine. Nominal diameter: 40 to 400 *Sizes over 400 are available upon consultation. 【Features】 〇 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! 〇 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! 〇 Construction is significantly faster compared to steel pipes, and even when joints are necessary, a 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. ○ Polyethylene pipes have low friction resistance and minimal scale adhesion, so no time-based accumulation is necessary.
