Notice of Participation in the 2025 Hiroshima Waterworks Exhibition

A rich selection of pipes, fittings, and irregular pipes allows for detailed responses to user needs!

WED pipes are dual-layer pipes made of high-density polyethylene, available in sizes that conform to ISO standards. Nominal diameter: W40 to W350 【Features】 ○ 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. ○ Pipes with a nominal diameter of W100 or less can be delivered in long lengths (tab-wound). ○ The delivery of long-length pipes can reduce labor and shorten construction time, leading to cost savings. ○ Polyethylene pipes are flexible and have excellent seismic resistance.

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

GNGWDA 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: W40 to W100 (The conduit dimensions conform 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. ○ They are long and highly flexible, allowing for bending while extending the pipe. ○ They are ideal for soft ground such as marshy areas and reclaimed land, and they also excel in earthquake resistance. ○ The outermost layer is coated with low-density polyethylene with added carbon black, providing excellent weather resistance and corrosion resistance, making it suitable for exposed pipes. ○ The EF fusion and automatic butt fusion create a reliable pipeline with a unified structure. ○ It possesses sufficient weather resistance and internal and external pressure strength as a bridge attachment pipe.
