Anti-scaling property
Leveraging the 'lotus leaf hydrophobic' principle, we utilize organic polymers and specialized processes to elevate the water contact angle on the pipeline surface to 111° (standard control ≥105°), significantly surpassing ordinary polyethylene's 88°-92°. This enhancement ensures a smoother pipeline surface, diminishes calcium and magnesium ion adsorption, and reduces energy consumption. This anti-scaling feature, combined with the pipeline's antibacterial properties, ensures a genuinely antibacterial pipeline, avoiding non-contact failure issues caused by scaling. (Water Contact Angle: 90° < water contact angle < 180° indicates a hydrophobic effect.)Hydrophobic patency
Our pipes boast an exceptionally smooth inner wall compared to conventional plastic pipes, leading to reduced flow resistance and heightened water transmission capacity. This superior inner wall smoothness surpasses that of traditional polyethylene pipes, addressing the problem of increased energy consumption during long-term pipe network operation. Ideal for the drinking water industry, our design ensures efficient performance.
Anti-bacterial Performance
Our pipes incorporate an ionic antibacterial agent within the inner wall. Tested under JC/T939-2004 standards by the Guangdong Microbiological Analysis and Testing Center, the antibacterial rate exceeds 99.99% against Escherichia coli and Staphylococcus aureus. This ensures the elimination of microorganisms on the tube wall, prevents microbial film formation, and guarantees a permanent antibacterial effect.
Terrain adaptability
Our pipes are designed to adapt to varying terrains. The flexibility of our plastic pipes reduces the need for numerous fittings and accommodates terrain shifts, ensuring reliable performance even under pressure.
Economical and efficient
Our pipes are significantly lighter than concrete, galvanized, and steel pipes, making them easier to handle and install. This lightweight nature, combined with reduced manpower and equipment needs, drastically lowers project installation costs.
Long Service Life
Made from durable polyethylene material, our pipes are designed for long-term use, with an extrapolated service life of 50 years under normal working conditions.
