Our PP-R drinking water pipes, widely embraced in developed countries, utilize homogeneous welding technology for seamless cold and hot water transportation. These pipes excel in both technical performance and economic efficiency, far surpassing similar products. Notably, their superb hygienic properties meet the highest standards for health and environmental protection throughout their lifecycle—from production to disposal and recycling.
Our product boasts remarkable features including heat resistance, pressure resistance, heat preservation, and energy efficiency. With a long service life and cost-effectiveness, it is poised to outshine existing water pipe solutions. Unlike metal pipes, which can lead to oxidation, contamination, and secondary pollution, our PP-R pipes are crafted from environmentally friendly, recyclable materials that fortify polypropylene. These pipes do not leach harmful substances or accumulate scale, ensuring compliance with all sanitary and health standards. Ideal for drinking water and food industry applications, PP-R pipes are the premier choice for hygienic and eco-friendly water transportation.

Features
★ Hygienic and non-chemical, this eco-friendly building material is crafted from polyolefin (PP-R), composed solely of carbon and hydrogen. Its superb hygienic performance ensures reliability.
★ Experience convenience and reliability with our easy hot-melt connection. Complete joint connections swiftly, saving both time and effort.
★ Enjoy superior heat preservation and energy efficiency! With a thermal conductivity of just 0.24W/m.k—only 1/20th of metal pipes—our fittings minimize heat loss in hot water systems.
★ Boasting light weight and high specific strength, our fittings are 1/8th the weight of steel pipes. They offer excellent pressure resistance, outstanding toughness, and robust impact resilience.
★ Designed with smooth inner and outer walls, our product ensures minimal flow resistance, leading to energy-efficient fluid transportation systems.
★ Capable of withstanding high temperatures, our fittings operate at 70ºC for extended periods and can handle up to 95ºC for short durations.
★ With corrosion resistance and non-scaling properties, our fittings ensure clog-free operations and prevent unsightly yellow rust spots in basins and bathtubs.
★ Boasting a long service life, our fittings can reliably perform for over 50 years.
Product Application Range
★ Ideal for both hot and cold water pipe systems.
★ Perfect for heating systems, including floor, wall, and radiant heating.
★ Suitable for pure water piping systems.
★ Compatible with central and centralized air conditioning systems.
Pipe Connection
★ Mark the socket depth on the pipe insertion end post-piping.
★ Clean the connecting end faces of pipes and fittings before threading the pipe into the joint cover.
★ Heat pipes and fittings using a hot melt machine. Ensure heating parameters meet the technical requirements of the specific hot melt machine.
★ Once heated, remove pipes and fittings immediately and insert straight without rotation to the marked depth, forming a uniform flange at the joint.
★ Apply the pipe joint cover post-welding for added security.
★ The pipes and fittings will melt into a unified structure, achieving a truly perfect match.
