Notice of Participation in the 2024 Kobe 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 usage rate of polyethylene pipes is the highest in the world. This allows for the utilization 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 periods, leading to cost savings in construction. ○ Polyethylene pipes are flexible and have excellent earthquake 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 protects against external pressure. ○ The rigid polyurethane insulation layer prevents freezing of fluids inside the conduit. ○ Pipes with a nominal diameter of W100 or less can be delivered to the site as long pipes (tab-wound). ○ The use of long pipes can reduce labor and shorten construction time, leading to cost savings. ○ The long pipes are flexible and can be extended while bending. ○ 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 containing carbon black, which offers excellent weather resistance and corrosion resistance, making it suitable for exposed pipes. ○ EF fusion and automatic butt fusion create a reliable pipeline with a unified structure. ○ It has sufficient weather resistance and internal and external pressure strength for use as bridge attachment pipes.

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

GNGWA 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: 150S to 250S (The conduit dimensions adhere to ISO standards.) 【Features】 ○ The composite pipe structure of polyethylene and aramid fibers provides high internal pressure strength, and the corrugated steel pipe installation 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 shortens the construction period, 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. ○ EF fusion and automatic butt fusion create a reliable pipeline with a unified structure. ○ It has sufficient weather resistance and internal/external pressure strength for use as bridge attachment pipes.

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.
