Anti-scaling property
Hydrophobic patency
Our innovative pipeline boasts a remarkably smoother inner wall compared to conventional plastic pipes, dramatically reducing flow resistance and enhancing water transmission capability. The inner wall's optimal smoothness surpasses traditional polyethylene pipes, effectively addressing increased energy consumption issues in long-term pipe network operations. Specifically engineered for the drinking water industry, this pipeline model leads the way in efficient water transport.
Anti-bacterial Performance
Our pipes integrate a state-of-the-art ionic antibacterial agent within the inner wall, rigorously tested per JC/T939-2004 standards by Guangdong Microbiological Analysis and Testing Center. The antibacterial component achieves an outstanding > 99.99% effectiveness rate against Escherichia coli and Staphylococcus aureus, eliminating microorganisms from the tube wall, preventing microbial film formation, and delivering a permanent, robust antibacterial performance.
Terrain adaptability
Designed to withstand pressure while maintaining flexibility, our pipes adapt seamlessly to shifting terrains. This flexibility allows for fewer pipe fittings and enables the pipeline to conform to terrain changes, ensuring efficient and flexible installations.
Economical and efficient
Our pipeline's lightweight nature, compared to traditional concrete, galvanized, and steel pipes, ensures effortless handling and installation. The reduced need for manpower and specialized equipment translates into significantly lowered project installation costs, offering both economic and operational efficiency.
Long Service Life
Crafted from premium polyethylene material, our pipeline is engineered for longevity with a projected service life of up to 50 years under normal working conditions, promising enduring reliability and performance.
