Features
★ Hygienic, non-chemical, and an environmentally friendly green building material. Crafted from polyolefin, PP-R's molecular structure consists solely of carbon and hydrogen elements, ensuring its hygienic performance is both dependable and trustworthy.
★ Installation that is both convenient and reliable: Utilizing homogeneous hot-melt connections, each joint connection can be completed swiftly, saving both time and effort for an efficient and hassle-free installation process.
★ Heat preservation and energy conservation champion: With a thermal conductivity of just 0.24W/m.k, this material is remarkably lower than metal pipes, resulting in minimal heat loss when used for hot water pipes.
★ Lightweight with exceptional specific strength: Boasting a specific gravity only about one-eighth that of steel pipes, this material offers high pressure test strength, superb toughness, and excellent impact resistance.
★ Smooth inner and outer walls minimize flow resistance, ensuring the fluid conveying system operates with optimal energy efficiency, leading to reduced energy consumption.
★ Withstanding high temperatures: Capable of enduring water temperatures of 70ºC for long-term use, and up to 95ºC for short-term use, showcasing remarkable heat resistance.
★ Corrosion-resistant, anti-scaling properties prevent fouling and clogging, as well as eliminating unsightly yellow rust stains in basins and bathtubs.
★ Exceptional longevity: Remarkably durable, with a normal service life expectancy exceeding 50 years.
Product Application Range
★ Comprehensive hot and cold water pipe systems for various applications.
★ Versatile heating systems, extending to floor, wall, and radiant heating solutions.
★ Efficient pure water piping systems for clean and safe water delivery.
★ Centralized air conditioning systems for optimal climate control.
Pipe Connection
★ Post-piping, clearly mark the socket depth at the pipe insertion end for precision.
★ Ensure cleanliness by wiping the connection end faces of pipes and fittings. Insert the pipe into the pipe joint cover seamlessly.
★ Employ a hot melt machine to heat the pipes and fittings for connection. Ensure heating parameters align with the technical standards of the machine.
★ Once the heating duration is reached, promptly remove and simultaneously join the pipe and fittings without rotation, reaching the marked depth evenly to form a consistent flange.
★ Securely attach the pipe joint cover post-welding to ensure a robust connection.
★ Achieve a flawless bond as pipes and fittings melt into a seamless unit, epitomizing a perfect match.
