Our PP-R environmental protection and health water supply pipe series are crafted under the rigorous ISO9001 quality system standards. These pipes are designed to deliver unparalleled safety and reliability, embodying the highest levels of environmental stewardship and health-conscious manufacturing.
The PP-R drinking water pipe, a modern innovation hailed in developed nations worldwide, leverages advanced homogeneous welding technology to excel in both cold and hot water transport projects. Its superior technical performance and economic efficiency outshine comparable alternatives. Notably, its exceptional hygienic properties meet stringent health and environmental standards throughout its lifecycle—from production and usage to disposal and recycling.
Our PP-R pipes boast remarkable heat resistance, pressure endurance, thermal insulation, and energy efficiency, ensuring longevity and cost-effectiveness. As it becomes the preferred choice over traditional piping systems, it combats secondary pollution effectively. With the presence of diverse chemical substances, minerals, and impurities in water, traditional metal pipes may oxidize and degrade, harming water quality. However, PP-R pipes, made from recyclable and eco-friendly polypropylene, resist heavy metals and harmful substances release. Their non-scaling, health-centric design complies with stringent sanitary standards, making them ideal for drinking water and food industry applications.

Features
★ Hygienic, non-chemical, and eco-friendly green building material. The raw PP-R material, polyolefin, consists solely of carbon and hydrogen, ensuring reliable hygienic performance.
★ Convenient and reliable installation: With homogeneous hot-melt connection, joints are completed swiftly, ensuring a time-efficient and hassle-free setup.
★ Superior heat preservation and energy efficiency: Boasting a thermal conductivity of just 0.24W/m.k, it is 20 times more insulating than metal pipes, minimizing heat loss in hot water applications.
★ Lightweight yet robust: Our product weighs merely one-eighth of steel pipes, offering high-pressure test strength, excellent toughness, and superior impact resistance.
★ Smooth inner and outer walls: The design ensures minimal flow resistance, optimizing energy consumption in fluid conveyance systems.
★ Exceptional heat resistance: Capable of withstanding continuous temperatures of 70ºC and short-term peaks up to 95ºC, ensuring long-term reliability.
★ Corrosion-resistant and non-scaling: Prevents pipe fouling, clogging, and the formation of unsightly yellow rust spots in basins and bathtubs.
★ Extended service life: Engineered for durability, with a standard service life exceeding 50 years.
Product Application Range
★ Ideal for hot and cold water pipe systems.
★ Perfect for heating systems, including floor, wall, and radiant heating configurations.
★ Suitable for pure water piping systems.
★ Integral to central (centralized) air conditioning systems.
Pipe Connection
★ After pipe installation, mark the socket depth at the pipe insertion end for accuracy.
★ Clean the connecting end faces of both pipes and fittings. Insert the pipe into the pipe joint cover to prepare for a seamless connection.
★ Use a hot melt machine to heat both the pipes and fittings. Ensure heating parameters comply with the technical specifications of the hot melt machine.
★ Once heated adequately, swiftly remove the pipe and fittings, then insert them together without rotation to the marked depth, forming a uniform flange at the joint.
★ Secure the pipe joint cover post-welding for a complete finish.
★ Achieve a flawless fit: Pipes and fittings melt seamlessly into one cohesive unit, ensuring a perfect match every time.
