"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.

Water supply and drainage (insulated) pipe GNGWA - Outstanding freeze prevention performance!

Lightweight, long-length, high strength, and excellent insulation performance! It is a high-performance freeze prevention pipe!

GNGWA is increasingly being adopted for bridge attachments and suspended piping due to its unique characteristics of lightweight, flexibility, and earthquake resistance that are not found in other types of pipes. Nominal diameter: 150S to 250S (The conduit dimensions adhere to ISO standards.) 【Features】 - The composite pipe structure of polyethylene and aramid fibers provides high internal pressure strength, and the corrugated steel pipe structure protects against external pressure. - The rigid polyurethane insulation layer prevents the freezing of fluids inside the conduit. - Pipes with a nominal diameter of W100 or less can be delivered to the site as long-length pipes (tab-wound). - The use of long-length pipes allows for labor-saving in construction and shortening of construction periods, leading to cost reductions. - The long length and excellent flexibility allow for bending while extending the pipe. - It is ideal for soft ground such as marshy areas and reclaimed land, and it also excels in earthquake resistance. - The outermost layer is coated with low-density polyethylene containing carbon black, which provides excellent weather resistance and corrosion resistance, making it suitable for exposed pipes. - Through EF fusion and automatic butt fusion, it creates a reliable pipeline with a unified structure. - It has sufficient weather resistance and internal and external pressure strength as a bridge attachment pipe.
