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

Protech Engineering (Booth Number: 240) will be exhibiting at the "Hokkaido Construction Development Comprehensive Exhibition 2025," scheduled to be held on October 8 (Wednesday) and 9 (Thursday), 2025. On the day of the event, we will provide detailed explanations of the following disaster prevention products using models, panels, and various materials. ◆ Main Exhibited Products ◆ - Energy-absorbing rockfall protection fence / ARC Fence (model display) - Landslide debris protection fence / Slope Guard Fence Type LE (model display) - Pile-type (pile foundation) debris flow and driftwood countermeasure for non-flowing streams / Urban Guard - Avalanche prevention piles / Tri-Pile - Avalanche protection fence / Slope Guard Fence Type LS - High energy-absorbing rockfall protection fence / Macro Fence In addition, we will have a variety of materials on disaster prevention products developed independently by Protech Engineering, so we kindly invite you to visit our booth.

Profect Co., Ltd. will hold a seminar on October 3rd (Friday) themed around the IT Implementation Subsidy 2025 and our developed and sold production management system "TED." This year's IT Implementation Subsidy has seen a significant decrease in the acceptance rate compared to previous years. Many companies are struggling with the situation of having wanted to implement IT tools but being rejected. In this seminar, we will explain why the acceptance rate has dropped, the background behind it, and the key points for being accepted. Additionally, we will introduce our initiatives that have achieved a 100% acceptance rate so far this year and the reasons why our production management system "TED," registered as an IT tool, is chosen. To accommodate busy schedules, this seminar will be held in a hybrid format, allowing for both in-person attendance and online participation via Zoom. Please choose your preferred method of participation according to your convenience. If you are currently considering applying for the IT Implementation Subsidy or are interested in production management, we encourage you to join us. We sincerely look forward to your application.

An international forum aimed at promoting the circular economy and closed-loop economy, "Closed Loop Recycle Forum 2025 (hereinafter referred to as CLRF2025)," will be held for two days from November 25 (Tuesday) to 26 (Wednesday) at The Oriental Terrace in Chuo Ward, Hamamatsu City, Shizuoka Prefecture. In Europe, closed-loop recycling practices are already advancing. We have organized this international forum as a platform to connect the forefront of Europe with Japan's challenges, striving for a future that balances economic viability and environmental sustainability. A total of 12 speakers, including Chairman Kajiwara of the Waste and 3R Research Foundation and Director Kaneko of the Ministry of the Environment's Container and Packaging Recycling Division, along with leading recycling operators and researchers from Japan and Europe, will present advanced examples of the circular economy and closed-loop economy. Furthermore, through discussions on the feasibility and challenges of implementation in Japan, we will explore hints for sustainable business models that companies and local governments should aim for.
