Anti-scaling property
Inspired by the 'lotus leaf hydrophobic' principle, our advanced organic polymers and unique processes significantly enhance the water contact angle on the pipe surface to an impressive 111° (standard control ≥105°). This far surpasses the typical 88°-92° of regular polyethylene, resulting in a much smoother pipeline surface and drastically reducing the adsorption of calcium, magnesium ions, and other substances. Consequently, energy consumption for water transportation is minimized. Additionally, the synergistic anti-scaling and antibacterial properties ensure genuine antibacterial performance, effectively preventing issues arising from non-contact failures between the antibacterial layer and the fluid due to scaling. (Water contact angle: The contact angle of water droplets on the material surface; 90° < water contact angle < 180° indicates hydrophobic effects.)Hydrophobic patency
Boasting a smoother inner wall than conventional plastic pipes, our pipes offer reduced flow resistance and superior water transmission capacity. The enhanced smoothness exceeds that of traditional polyethylene pipes, addressing the problem of increased energy consumption over long-term pipe network operations. This makes it an ideal pipe type for the drinking water industry.
Anti-bacterial Performance
Enriched with an ionic antibacterial agent on the inner wall, our pipes achieve an antibacterial rate of >99.99% against Escherichia coli and Staphylococcus aureus, as per JC/T939-2004 standards tested by the Guangdong Microbiological Analysis and Testing Center. This ensures the elimination of microorganisms attached to the tube wall, prevents the growth of surface microbial films, and guarantees a permanent antibacterial effect.
Terrain adaptability
Our pipes, designed with the flexibility of plastic in mind, adapt seamlessly to pressure variations and terrain changes. Flexible laying reduces the need for numerous pipe fittings, ensuring smooth transitions as the terrain settles.
Economical and efficient
Significantly lighter than concrete, galvanized, or steel pipes, our pipes are easy to handle and install. Reduced manpower and equipment requirements translate to substantial cost savings for your projects.
Long Service Life
Engineered for longevity, our polyethylene pipes have an extrapolated service life of 50 years under normal working conditions, promising enduring performance.
