Anti-scaling Property
Inspired by the 'lotus leaf hydrophobic' principle, our advanced organic polymers and unique processes elevate the water contact angle on the pipeline surface to an impressive 111° (standard control ≥105°), significantly surpassing traditional polyethylene's 88°-92°. This enhancement optimizes surface smoothness, reduces the adsorption of calcium, magnesium ions, and other substances, and lowers pipeline water energy consumption. The combined anti-scaling and antibacterial properties ensure true antibacterial efficacy, preventing contact failure between the antibacterial layer and fluid due to scaling. (Water Contact Angle: A hydrophobic effect is achieved when 90° < water contact angle < 180°.)Hydrophobic Patency
Our innovative pipelines feature smoother inner walls compared to conventional plastic pipes, resulting in lower flow resistance and higher water transmission capacity. This superior smoothness minimizes energy consumption over long-term operations, making our pipes the optimal choice for the drinking water industry.
Anti-bacterial Performance
Our pipes incorporate an ionic antibacterial agent into the inner wall, tested to comply with the JC/T939-2004 'Antibacterial Performance of Antibacterial Plastic Pipe for Construction' standards by the Guangdong Microbiological Analysis and Testing Center. With an antibacterial rate of >99.99% against Escherichia coli and Staphylococcus aureus, our pipes effectively eliminate microorganisms, prevent surface microbial film growth, and maintain permanent antibacterial properties.
Terrain Adaptability
Designed for diverse terrains, our flexible plastic pipes can adapt to pressure and terrain settlement, reducing the need for additional fittings and ensuring seamless installation. This flexibility enhances the pipe's performance and longevity in variable environments.
Economical and Efficient
Our pipes are lighter and easier to handle compared to concrete, galvanized, and steel pipes, significantly reducing manpower and equipment requirements. This results in substantial cost savings for installation and overall project expenses.
Long Service Life
Crafted from high-quality polyethylene, our pipes boast a long-term design life with an extrapolated service lifespan of 50 years under standard working conditions, ensuring durability and reliability for decades.
