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 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 to 250 【Features】 - The inner surface of the pipe and the outermost layer are made of polyethylene material, which has excellent corrosion resistance, is strong against salt damage, and has high 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 needed, it is safer with a reliable fusion system! - 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 there is no need for time-based additions. In 2024, we carried out the replacement work for the underwater water supply and drainage pipe from Atami City to Hatsushima. The installation was completed with a single piece of 6,745 meters 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.

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 or burial conditions. The installation work underwater can minimize the environmental impact on the underwater environment by using an automatic burial machine. Nominal diameter: 40–400 *Sizes over 400 are available upon consultation. 【Features】 〇 The inner surface and outermost layer of the pipe are made of polyethylene material, which is highly resistant to corrosion and salt damage, and reinforced with metal materials for strong mechanical strength! 〇 Long-length manufacturing and on-site delivery are possible, eliminating the need for joint connections on the seabed, allowing for reliable installation in a short construction period! 〇 Installation is significantly faster compared to steel pipes, 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. ○ Polyethylene pipes have low friction resistance and minimal scale adhesion, so no time-dependent accumulation is required.

A wide variety of pipes, fittings, and irregular pipes allows for detailed responses to user needs!

The WE pipe is a single-layer pipe made of high-density polyethylene, available in sizes compliant with ISO standards. Nominal diameter: W150 to W1500 【Features】 ○ It has achieved good results in the JWWA K-14-2017 chlorine water resistance test. ○ It applies the international standard ISO4427, which originated in Europe, where the penetration rate of polyethylene pipes is the highest in the world. This allows for the use of a wide variety of fittings. ○ Made from black high-density polyethylene with excellent weather resistance, making it suitable for exposed piping. ○ The delivery of long pipes enables labor-saving in construction and shortens construction periods, leading to cost reductions. ○ Particularly in the field of large-diameter piping, our WE not only provides product supply but also has extensive experience in engineering and piping installation work. ○ Polyethylene pipes are flexible and have excellent earthquake resistance. ● Public Interest Incorporated Foundation Japan Sewage Works New Technology Organization Construction Technology Review Certificate Target pipe types: WE-13.6, WE-11, WEETAX-11 / Target nominal diameters: W150, W200, W250, W300

On November 20, 2025 (Thursday) and December 2, 2025 (Tuesday) from 11:00 to 14:00, our representative, certified public accountant and tax accountant Koichi Yokoyama, will be speaking at a free webinar hosted by Otsuka Shokai. He will explain important points to note regarding the revised Construction Business Act. [Construction Business Act / Public Works Optimization Promotion Act] - Prevention of omissions in the description of construction contracts - Obligation to notify "risk" information before contract signing by the contractor - Mutual exchange of original copies of construction contracts - Digitization of estimates, contracts, and order forms/acceptance letters We are entering an era where contracts must be documented in writing and stored electronically. Paperlogic is fully committed to supporting companies that have begun the transition from paper to digital.
