Product Description

In the realm of modern drinking water infrastructure, traditional piping solutions such as cement mortar ductile iron pipes, plastic coating steel pipes, and PE pipes present significant challenges. These include microbial proliferation, yellowing of water due to pipeline corrosion, internal scaling, and diminished water transmission capacity. Such issues not only compromise the operational efficiency of water networks but also lead to so-called 'secondary pollution,' resulting in subpar water quality at the consumer's end.

In response to the growing demands for superior quality of life, Shandong Donghong Pipe Industry Co., Ltd. has leveraged over two decades of expertise in plastic composite pipeline R&D and manufacturing to tackle the problems of 'secondary pollution' and reduced transmission capacity in existing pipeline networks. Utilizing advanced functional material development, innovative pipeline structural design, and cutting-edge special process technologies, Donghong has engineered specialized composite pipelines that boast remarkable anti-bacterial and anti-scaling properties. These innovative solutions ensure the intrinsic safety and enhanced performance of modern drinking water pipeline networks.

Product Features

Anti-scaling property

Drawing inspiration from the incredible 'lotus leaf hydrophobic' effect, we utilize advanced organic polymers and specialized processes to elevate the water contact angle on the pipeline surface to a remarkable 111° (with standard control parameters set at ≥105°). This is a significant enhancement compared to standard polyethylene's 88°-92°, ensuring superior surface smoothness. The result? A dramatic reduction in the adsorption of calcium, magnesium ions, and other substances, leading to decreased energy consumption in water transmission. Our pipes effectively combine anti-scaling with antibacterial properties to ensure true and lasting antibacterial performance, mitigating the risk of non-contact failure between the antibacterial layer and fluid due to scaling.

 

Hydrophobic patency

Our cutting-edge pipes boast an exceptionally smooth inner wall compared to conventional plastic alternatives, significantly reducing flow resistance and enhancing water transmission efficiency. This superior smoothness outperforms traditional polyethylene pipes, addressing energy consumption concerns in long-term pipe network operations. Specifically designed for the drinking water sector, our pipes offer unmatched performance and reliability.

Anti-bacterial Performance

Incorporating ionic antibacterial agents into the pipe's inner wall, our product meets the stringent JC/T939-2004 standards for antibacterial performance as verified by Guangdong Microbiological Analysis and Testing Center. The antibacterial rate exceeds 99.99% against common bacteria like Escherichia coli and Staphylococcus aureus, eliminating any microorganisms on the tube wall. This prevents the development of microbial films on the surface, ensuring a continuous and permanent antibacterial effect.

Terrain adaptability

Designed with flexibility in mind, our pipes accommodate pressure effectively while allowing for easy, flexible laying that adapts to varying terrains. This flexibility reduces the need for additional fittings and ensures seamless performance even when the terrain settles.

 

Economical and efficient

Our pipes are significantly lighter than traditional concrete, galvanized, or steel pipes, making them easy to handle and install. This lightweight nature, coupled with reduced manpower and equipment demands, translates to considerable cost savings in installation projects.

Long Service Life
Crafted from premium polyethylene materials, our pipes promise an impressive long-term design life. Under standard working conditions, they are projected to last up to 50 years, offering unmatched durability and reliability.
