三井金属エンジニアリング List of Products and Services

Polyethylene pipes have become widespread, particularly in water supply and drainage systems, due to their long-term reliability and seismic resistance, and an expansion of market share is expected in the future! 【Features of MESCO Pipes (High-Density Polyethylene Pipes)】 - The use of long pipes allows for labor-saving construction and a reduction in construction time, demonstrating high cost performance. - By adopting a composite structure, they can be used under high internal pressure. - They are highly flexible, strong against earthquakes, and can be installed along the terrain while bending. - They have excellent weather resistance, making them recommended for exposed piping such as bridge installations. - A wide range of large-diameter pipes up to a nominal diameter of 1,500 mm is available! They can also be used for agricultural water and rainwater drainage applications. 【MESCO's Joint System】 - EF Joint Method: Allows for easy and reliable connections / Stable fusion quality in a short time / Can be installed in narrow spaces. - Automatic Butt Fusion Method: Capable of large-diameter butt fusion (with domestic achievements up to a nominal diameter of W1500) / Integration through thermal fusion enables reliable construction.

The composite pipe enhances internal pressure strength and suppresses creep. The anti-corrosion layer protects the polyethylene conduit from external damage and UV degradation, maintaining pipe performance over a long period. It has been included in the common specifications of NEXCO (as of July 2019). Nominal diameter: W75 to W350 【Features】 ● Excellent characteristics of polyethylene pipes 　・Lightweight and flexible. 　・Superior earthquake resistance. 　・Low friction, allowing for downsizing of pipe dimensions. (Note: Hydraulic calculations need to be verified.) 　・Corrosion-resistant. ○ Utilizing the above characteristics of polyethylene pipes, we have developed an advanced composite polyethylene pipe reinforced with aramid fibers using our unique technology, which has been registered in NETIS. NEXCO Common Specifications for Mechanical Equipment Construction "Fiber-Reinforced Polyethylene Pipe (FRPE) Target Product" ○ It has already been adopted for the new installation and renewal work of emergency water supply mains in tunnels such as the Shin-Tomei Expressway. It is also used as the water supply main for fire protection equipment in the Central Circular Shinjuku Line tunnel.
