Product Description

Current options for drinking water pipes largely consist of cement mortar ductile iron pipes, plastic-coated steel pipes, and PE pipes. These materials often face significant challenges such as microbial growth, water discoloration due to pipeline corrosion, scaling on the inner walls, and a reduction in water transmission capacity. These issues not only compromise the operational economy of the distribution network but also lead to 'secondary pollution,' which directly affects the water quality for end-users, rendering the water unfit for consumption.

Driven by the pursuit of enhancing the quality of life and addressing the pressing issues of 'secondary pollution' and diminished transmission capacity in current pipeline networks, Donghong shares its wealth of over 20 years of expertise in the research and development of plastic composite pipelines. By leveraging the company's advancements in functional material development, innovative pipeline structural design, and proprietary special process technologies, we have successfully introduced groundbreaking composite pipeline products. These products boast remarkable anti-bacterial and anti-scaling capabilities, ensuring the drinking water pipeline network achieves optimal intrinsic safety and cleanliness.

Product Features

Anti-scaling property

Drawing on the groundbreaking principle of 'lotus leaf hydrophobicity', our cutting-edge technology employs organic polymers and innovative processes to elevate the water contact angle on the pipeline surface to an impressive 111° (standard control ≥105°). This far surpasses the typical polyethylene range of 88°-92°, significantly enhancing the surface smoothness of the pipeline. This remarkable feature effectively reduces the adsorption of calcium and magnesium ions along with other substances in the water, thereby minimizing the pipeline's energy consumption. The synchronized anti-scaling and antibacterial effects work in harmony to ensure a genuine antibacterial performance, preventing the issue of non-contact failure between the antibacterial layer and the fluid due to scaling. (Water contact angle: the angle formed by water droplets on a material's surface; a hydrophobic effect is achieved when the angle is between 90° and 180°.)

 

Hydrophobic Patency

When compared to conventional plastic pipes, our flexible HDPE pipes boast a smoother inner wall, reducing flow resistance and enhancing water transmission capabilities. The exceptional inner wall smoothness, surpassing that of traditional polyethylene pipes, addresses the challenge of increased energy consumption in long-term pipe network operations. These pipes are meticulously designed to meet the demanding standards of the drinking water industry.

Anti-bacterial Performance

Our pipe's inner wall is fortified with an ionic antibacterial agent. Tested in accordance with the JC/T939-2004 'Antibacterial performance of antibacterial plastic pipe for Construction' by the prestigious Guangdong Microbiological Analysis and Testing Center, it boasts an impressive antibacterial rate of > 99.99% against harmful bacteria like Escherichia coli and Staphylococcus aureus (as per standard testing requirements). This formidable feature eradicates microorganisms attached to the pipe wall, preventing microbial film formation and ensuring a permanent antibacterial effect.

Terrain Adaptability

Our flexible HDPE pipe takes into account the pipe's flexibility under pressure, enabling adaptable laying that reduces the need for additional pipe fittings. It seamlessly adjusts to terrain changes, offering a reliable solution in environments where the ground may settle.

 

Economical and Efficient

Offering a lighter alternative to concrete, galvanized, and steel pipes, our HDPE pipes are easy to handle and install. With reduced manpower and equipment requirements, they significantly lower installation costs, making your projects more economical and efficient without compromising on quality.

Long Service Life
Constructed from robust polyethylene material, our pipes are designed for long-term performance. Under normal working conditions, the projected service life extends up to an impressive 50 years, ensuring longevity and dependability for your infrastructure.
