MESCO pipes support "living" in every place from the ground to the seabed. Based on the trust and achievements cultivated over more than 50 years of responding to diverse needs, we strive to improve our technical capabilities in piping lines and are committed to providing "valuable products" every day. Polyethylene pipes, backed by excellent corrosion resistance and flexibility, hold an overwhelming share as piping materials for infrastructure development such as water supply, sewage, and gas in Europe and the United States, particularly within the EU, and have recently gained significant attention in our country as well. **Features of MESCO Pipes** - The use of long-length pipes allows for labor-saving construction and shortened construction periods, demonstrating high cost performance. - By adopting a composite structure, they can be used under high internal pressure. - Their excellent flexibility makes them earthquake-resistant and suitable for construction that follows the terrain. - With outstanding weather resistance, they are suitable for exposed piping such as bridge installations. - We offer a range of large-diameter pipes up to a nominal diameter of 1,500 mm, making them suitable for applications such as agricultural water and rainwater drainage. MESCO pipes provide the optimal products tailored to your needs and usage conditions through a rich lineup, responding to your requests.

【Usage Details】 Underwater water supply / Seawater intake and discharge / Fish farming 【Pipes available for this use】 WED / WE / WEETDA / WEETA / WNG / WEETS A wealth of knowledge and experience accumulated through numerous special construction projects. We support the lifelines of your community with our "comprehensive proposal capabilities" from planning to construction!

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.

Heat supply refers to the provision of hot or cold water from a heat source to facilities through pipes. MESCO's polyethylene pipes excel in properties such as heat resistance, insulation, and workability, and have been adopted for numerous heat supply-related applications including geothermal binary power generation, biomass power generation, hot springs, district heating and cooling, and waste heat utilization. 〇 MESCO pipes suitable for heat supply-related applications PXE / GNGAR / GNGRT 〇 Features - Excellent heat resistance and chemical stability make them suitable for hot water and hot spring piping. Maximum operating temperature: PXE / GNGAR: 95°C, GNGRT: 80°C - GNGAR / GNGRT minimizes temperature drop of fluids due to their insulation layer. - Excellent corrosion resistance allows for direct burial installation. - Superior flexibility makes them earthquake-resistant and allows for natural bending during installation. - Excellent weather resistance enables their use as exposed piping.

Chemical solution refers to a general term for liquids containing chemical substances used in factories and similar settings, and chemical solution piping refers to the piping used to transport these solutions. MESCO pipes excel in properties such as chemical resistance, heat resistance, thermal insulation, and earthquake resistance, and have a proven track record of being adopted for chemical solution piping. 〇 MESCO pipes suitable for chemical solution piping For ambient temperature fluids: WE(D) / WEET(D)A / GNGW(D)A (maximum operating temperature: 40°C) For thermal fluids: PXE / GNGAR / GNGRT (maximum operating temperature PXE / GNGAR: 95°C, GNGRT: 80°C) 〇 Features - Excellent chemical resistance allows for use with various chemical solutions (the chemical resistance of MESCO pipes is detailed in the polyethylene pipe brochure for chemical solutions). They also have excellent wear resistance, making them suitable for slurry transport. - GNGW(D)A / GNGAR / GNGRT have excellent thermal insulation due to their insulating layer. - Their excellent flexibility makes them resilient to earthquakes and provides long-term reliability. - Their excellent weather resistance makes them suitable for exposed piping, such as rack piping within factories.
