Product Description

The traditional drinking water pipes, predominantly cement mortar ductile iron, plastic-coated steel, and PE pipes, often encounter significant issues such as microbial proliferation, yellowing of water due to pipeline corrosion, scaling on the inner walls, and diminished capacity for water transmission through the pipe network. These challenges not only compromise the operational economy of water networks but also lead to 'secondary pollution' at the user's side, resulting in deteriorated water quality and unqualified supply.

Embracing people's aspirations for a superior living experience, Shandong Donghong Pipe Industry Co., Ltd. has addressed the challenges of 'secondary pollution' and diminished transmission capacity in existing pipeline networks. Leveraging over 20 years of expertise in research, development, and manufacturing of plastic composite pipelines, and supported by advanced functional materials development, innovative pipeline structural design, and cutting-edge process technologies, we proudly introduce our special composite pipeline products. These pioneering pipelines, endowed with anti-bacterial and anti-scaling properties, ensure the intrinsic safety and purity of the drinking water pipeline network.

Connection Method

1. Elctric fusion connection.

2. Butt fusion Connection.

3. Flange Buckle Connection

Product Features

Anti-scaling property

Ingeniously inspired by the 'lotus leaf hydrophobic' principle, our product utilizes advanced organic polymers and specialized processes. The water contact angle on the pipe's surface is elevated to an impressive 111° (standard control ≥105°), significantly surpassing the average polyethylene range of 88°-92°. This enhancement not only elevates the surface smoothness of the pipeline but also minimizes the adsorption of calcium, magnesium ions, and other substances present in water, ultimately leading to decreased energy consumption. Additionally, the harmonious interplay of anti-scaling and antibacterial attributes ensures a genuine antibacterial effect, preventing issues like non-contact failure between the antibacterial layer and fluid due to scaling. (Water contact Angle: the contact Angle of water droplets on the material's surface, where 90° < water contact Angle < 180° indicates hydrophobicity.)

Hydrophobic patency

Our cutting-edge pipeline surpasses conventional plastic pipes with its smoother interior walls, resulting in significantly reduced flow resistance and enhanced water transmission. The superior smoothness of the inner wall outshines traditional polyethylene pipes, addressing the challenge of increased energy consumption over prolonged pipe network operation. Tailored specifically for the drinking water industry, this pipeline innovation stands as a benchmark for efficiency and performance.

Anti-bacterial Performance

Equipped with an ionic antibacterial agent embedded in the pipe's inner wall, our product has been rigorously tested according to the JC/T939-2004 standard, achieving an antibacterial rate exceeding 99.99% against Escherichia coli and Staphylococcus aureus, as verified by the Guangdong Microbiological Analysis and Testing Center. This ensures the elimination of microorganisms on the tube wall, preventing microbial film formation on surfaces and offering a lasting antibacterial effect.

Terrain adaptability

Our pipes boast exceptional flexibility, allowing them to adapt seamlessly to varying terrain conditions. This flexibility minimizes the need for additional fittings and enables the pipe to conform naturally to landscape changes, particularly during terrain settlement, ensuring optimal performance under pressure.

Economical and efficient

Our pipes are remarkably lightweight compared to concrete, galvanized, or steel alternatives, simplifying handling and installation. The reduced demand for manpower and equipment significantly lowers project installation costs, making it a cost-effective choice for your engineering needs.

Long Service Life
Crafted from premium polyethylene material, our pipes are designed for longevity, boasting an extrapolated service life of 50 years under normal working conditions. This ensures enduring reliability and performance for your projects.
