Our PP-R environmental protection and health water supply pipe series is meticulously crafted to meet the rigorous standards of the ISO9001 quality system, ensuring unparalleled quality and reliability.
The PP-R drinking water pipe, a cutting-edge innovation embraced by developed nations, employs state-of-the-art homogeneous welding technology for both cold and hot water transportation projects. Its superior technical performance and economic advantages outshine comparable products. Notably, its exceptional hygienic properties meet the most stringent health and environmental protection standards, from production through to disposal and recycling.
Boasting remarkable features such as heat resistance, pressure endurance, thermal insulation, and energy efficiency, our PP-R pipe promises longevity and cost-effectiveness. As it phases out traditional water pipes, it emerges as the leading solution. Unlike metal pipes, which risk secondary pollution by reacting chemically with water, our PP-R pipes are crafted from recyclable, eco-friendly polypropylene. This material prevents the release of harmful heavy metals and other toxic substances, ensuring a scale-free, hygienic pipe wall that adheres to the strictest sanitary standards. Our PP-R pipe stands as the paramount choice for sanitary and environmentally friendly water transportation in both the drinking water and food industry sectors.

Features
★ Hygienic, non-chemical, and an environmentally friendly building material. Crafted from polyolefin, PP-R's molecules consist solely of carbon and hydrogen, ensuring exceptional hygienic performance.
★ Convenient and reliable installation: With seamless homogeneous hot-melt connections, joints are completed quickly, making installation both efficient and time-saving.
★ Heat preservation and energy saving: Boasting a thermal conductivity of just 0.24W/m.k, a mere fraction (one-twentieth) of metal pipes. Ideal for hot water pipes with minimal heat loss.
★ Light weight and high specific strength: With a specific gravity about one-eighth that of steel pipes, it offers high pressure test strength, excellent toughness, and notable impact resistance.
★ Smooth inner and outer walls: Reduced flow resistance means the fluid conveying system consumes less energy, boosting overall efficiency.
★ High heat resistance: Reliable for conveying water at a constant 70ºC, and capable of withstanding up to 95ºC for short-term use.
★ Corrosion-resistant, non-scaling: Prevents pipe fouling, clogging, and the unsightly yellow rust spots in bathtubs and water basins.
★ Long service life: Engineered for longevity, with a normal service life extending beyond 50 years.
Product Application Range
★ Hot and cold water pipe systems.
★ Heating systems, including floor, wall, and radiant heating solutions.
★ Pure water piping systems.
★ Centralized air conditioning systems.
Pipe Connection
★ After piping, mark the socket depth at the pipe insertion end for accurate assembly.
★ Clean the connecting ends of pipes and fittings thoroughly. Insert the pipe into the pipe joint cover.
★ Heat the pipes and fittings with a hot melt machine, ensuring the heating parameters align with the machine's technical requirements.
★ Once heated, swiftly remove the pipe and fittings, inserting directly to the marked depth to form a uniform flange at the joint.
★ Secure the pipe joint cover post-welding for enhanced durability.
★ Achieve seamless integration as the pipes and fittings are completely melded into one unified structure, ensuring a flawless fit.
