Product Description

Current drinking water pipelines predominantly use materials like cement mortar ductile iron, plastic-coated steel, and PE pipes. These traditional materials often encounter numerous challenges such as microbial growth, yellowing water due to pipeline corrosion, scaling on the inner walls, and reduced water transmission capacity. These issues not only impair the operational efficiency of the network but also lead to 'secondary pollution' at the user end, compromising the water quality.

In response to the public's desire for improved living standards, Donghong Shares has tackled the pressing issues of 'secondary pollution' and reduced transmission capacity in pipeline networks. Leveraging over 20 years of expertise in R&D and the manufacturing of plastic composite pipelines, and utilizing our advancements in functional material development, pipeline structural design, and specialized processes, we've innovatively engineered composite pipeline products with exceptional anti-bacterial and anti-scaling properties. This breakthrough ensures the intrinsic safety of drinking water pipeline networks, providing a reliable and quality water supply for all.

Connection Method

1. Elctric fusion connection.

2. Butt fusion Connection.

3. Flange Buckle Connection

Product Features

Anti-scaling Property

Harnessing the naturally inspired 'lotus leaf hydrophobic' principle, our production employs premium organic polymers and specialized processes to elevate the water contact angle on the pipe surface to an outstanding 111°-far surpassing the conventional polyethylene range of 88°-92°. This innovation not only enhances the smoothness and cleanliness of the pipeline exterior but significantly diminishes the adsorption tendency for calcium, magnesium ions, and other substances. As a result, this reduces energy consumption for water transport. The pipeline's remarkable anti-scaling capability couples seamlessly with its antibacterial properties, delivering a truly effective antibacterial solution and eliminating the issues caused by scaling-induced non-contact failures between the antibacterial layer and the fluid. (Water contact angle: the degree of angle formed by water droplets on material surfaces; a range of 90° < water contact angle < 180° indicates hydrophobicity.)

Hydrophobic Patency

Boasting a smoother interior compared to standard plastic pipes, our pipes offer reduced flow resistance and increased water transmission efficiency. The enhanced smoothness of the inner wall outshines traditional polyethylene variants, addressing elevated energy consumption concerns during the prolonged operation of pipe networks. Specifically engineered for the drinking water sector, this pipeline represents a cutting-edge solution for efficient and sustainable water transportation.

Anti-bacterial Performance

Our product integrates an ionic antibacterial agent within the pipe's inner wall. As verified by the Guangdong Microbiological Analysis and Testing Center according to JC/T939-2004 'Antibacterial performance of antibacterial plastic pipe for construction', this component exhibits an impressive antibacterial rate of > 99.99% against harmful bacteria such as Escherichia coli and Staphylococcus aureus. This capability effectively eradicates tube wall-bound microorganisms, prevents microbial film growth, and offers a lasting antibacterial effect.

Terrain Adaptability

Considering the pipe's performance under pressure, its inherent flexibility facilitates seamless adaptation to varied terrains. This flexibility allows for a reduction in the necessity for additional pipe fittings and accommodates natural terrain settlement, ensuring reliability and durability.

Economical and Efficient

Significantly lighter than concrete, galvanized, and steel pipes, our pipes are designed for effortless handling and installation. The reduced need for manpower and equipment translates into substantial savings on project installation costs, making them an economically sound choice.

Long Service Life
Crafted from premium polyethylene materials, our pipes are designed with a long-lasting performance in mind. Under normal operational conditions, these pipes boast an impressive projected service lifespan of 50 years, ensuring sustained reliability and longevity.
