"Reuse V" is an indoor reuse system that can shorten the water outage time during the water supply pipe renewal work in apartment buildings compared to conventional methods. Taking environmental issues into consideration, we recycle temporary piping, which was previously disposable, into reusable temporary piping materials at our factory after use. Additionally, we use flexible joints for the water supply pipes from the vertical pipes to each household, making installation convenient. This eliminates the need for cutting and gluing with vinyl pipes, allowing for rapid water flow without waiting for the adhesive to set. 【Features】 ■ Uses lightweight and durable polyethylene pipes for piping materials ■ Vertical piping can be easily installed by simply attaching a joint to prevent disconnection after insertion into the receiving port ■ Allows for a 50% reduction in delivery time compared to the HIVP method ■ One person can install two systems in a day ■ Proven track record in many properties such as condominiums and public housing *For more details, please refer to the related link page or feel free to contact us.

Our company has developed a rental system for temporary piping materials called the "Reuse System," which utilizes polyethylene pipes for water distribution, significantly reducing the weight associated with temporary piping work. We have taken into account the safety of water quality, disposal methods in case of waste materials, pollution issues, and cost reductions due to material costs, labor costs, and shortened construction periods. By maintaining the piping materials instead of disposing of them, they can be reused multiple times depending on usage frequency. 【Features of Polyethylene Pipes for Water Distribution】 ■ Extremely high recyclability ■ Maintains flexibility down to -120°C ■ Excellent flexibility, demonstrating overwhelming strength against earthquakes and ground subsidence ■ Lightweight for easy handling, improving construction efficiency ■ Resistant to acids and alkalis *For more details, please refer to the related links page or feel free to contact us.
