"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 cure. 【Features】 - The piping materials are made of lightweight and durable polyethylene pipes. - The vertical piping can be easily installed by simply attaching a joint that prevents disconnection after insertion into the receiving mouth. - A 50% reduction in delivery time is possible compared to the HIVP method. - One person can install two systems in a day. - There are proven results in many properties, including 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 through savings in material costs, labor costs, and shortened construction periods. By performing maintenance instead of disposing of piping materials, they can be reused multiple times depending on usage frequency. 【Features of Polyethylene Pipes for Water Distribution】 ■ Highly recyclable material ■ Maintains flexibility down to -120°C ■ Excellent flexibility, demonstrating overwhelming strength against earthquakes and ground subsidence ■ Lightweight, making it easy to handle and improving construction efficiency ■ Resistant to acids and alkalis *For more details, please refer to the related links page or feel free to contact us.
