Product Description

In the current landscape of drinking water supply, traditional materials like cement mortar ductile iron pipes, plastic-coated steel pipes, and standard PE pipes face significant challenges. These include microbial growth, yellowing of water due to pipeline corrosion, scaling of inner walls, and reduced water transmission capacity. These issues not only diminish the economic efficiency of pipeline operations but also lead to 'secondary pollution' at the consumer's end, resulting in substandard water quality.

Driven by the desires for an enhanced quality of life and the need to address 'secondary pollution' and transmission capacity issues in existing pipeline networks, Shandong Donghong Pipe Industry Co., Ltd. has leveraged over two decades of expertise in R&D and manufacturing of plastic composite pipelines. By integrating advanced functional materials, innovative pipeline structural designs, and specialized development processes, we have pioneered exceptional composite pipeline products. These cutting-edge pipelines boast anti-bacterial and anti-scaling functions, ensuring the intrinsic safety and purity of drinking water supply networks.

Connection Method

Product Features

Anti-scaling property

Drawing on the extraordinary 'lotus leaf hydrophobic' principle, our cutting-edge use of organic polymers alongside special processes elevates the water contact angle on our pipeline surfaces to an impressive 111° (well above the standard control of ≥105°). This remarkable enhancement far surpasses ordinary polyethylene's 88°-92°, significantly optimizing the pipeline's smoothness and reducing its calcium, magnesium, and other ion adsorption capacities. Such advancements lead to lower energy consumption in water conveyance. Moreover, the pipeline's anti-scaling capabilities, in sync with its antibacterial properties, ensure a genuine antibacterial effect, effortlessly resolving issues of non-contact failure between the antibacterial layer and fluid due to scaling. For reference, the water contact angle, crucial in hydrophobicity, ranges between 90° and 180°.

 

Hydrophobic patency

Our innovative piping boasts a remarkably smoother inner wall compared to conventional plastic pipes, significantly diminishing flow resistance and elevating water transmission efficiency. Its superior smoothness over traditional polyethylene pipes tackles long-term energy consumption challenges in pipe network operations, establishing it as the ideal solution for the drinking water industry.

Anti-bacterial Performance

Incorporating ionic antibacterial agents into the pipe's inner wall, Shandong Donghong Pipe Industry Co., Ltd. adheres to the JC/T939-2004 standard for antibacterial performance, as validated by Guangdong Microbiological Analysis and Testing Center. Our pipes achieve an outstanding antibacterial rate of >99.99% against Escherichia coli and Staphylococcus aureus, effectively eliminating microorganisms clinging to tube walls and preventing the formation of microbial films. This innovation ensures a perpetual antibacterial effect, offering unrivaled cleanliness and safety.

Terrain adaptability

Our pipes are ingeniously designed to accommodate flexibility, particularly when under pressure. Their adaptable nature allows for flexible laying, minimizing the need for additional fittings and adapting seamlessly to any terrain shifts or settlements.

 

Economical and efficient

Our pipes are a testament to efficiency and economy. Significantly lighter than their concrete, galvanized, and steel counterparts, they promise ease of handling and installation. Reduced manpower and equipment demands translate into substantial reductions in project installation costs.

Long Service Life
Crafted from polyethylene pipe material, our pipes promise remarkable longevity, with an estimated service life of 50 years under standard operating conditions. This long-term design assures enduring performance and reliability.
