Product Description

Existing drinking water pipes, primarily composed of cement mortar ductile iron, plastic-coated steel, and PE pipes, face significant challenges. Issues such as microbial growth, yellowing of water due to pipeline corrosion, scaling on inner walls, and reduced water transmission capacity plague these systems. Consequently, these problems not only diminish the operational economy of the network but also lead to "secondary pollution" of water sources. This results in substandard water quality reaching the consumer's end, failing to meet the necessary standards.

In light of people's aspirations for an enhanced quality of life, addressing the limitations of existing pipeline networks is crucial. These networks are prone to "secondary pollution" and reduced transmission capacities. Shandong Donghong Pipe Industry Co., Ltd. leverages over 20 years of expertise in the research, development, and manufacturing of plastic composite pipelines. By harnessing the company's advancements in functional material development, pipeline structural design, and special process technologies, they have pioneered the creation of unique composite pipeline products. These pipelines boast anti-bacterial and anti-scaling properties, ensuring that the drinking water pipeline network achieves an unprecedented level of intrinsic safety.

Product Features

Anti-scaling Property

Inspired by the remarkable 'lotus leaf hydrophobic' principle, our cutting-edge technology uses organic polymers and specialized processes to elevate the water contact angle on our pipeline surfaces to an impressive 111° (standard control ≥105°), far surpassing ordinary polyethylene's 88°-92°. This enhancement significantly boosts the surface smoothness of our pipelines, diminishing the adsorption capacity of calcium, magnesium ions, and other substances, consequently lowering the energy consumption of water flow. Simultaneously, the anti-scaling and antibacterial properties of the pipeline synergize to deliver genuine antibacterial effects, effectively preventing the issue of non-contact failure between the antibacterial layer and fluid due to scaling. (Water contact angle: A measure of the angle at which a water droplet meets the material's surface, where 90° < water contact angle < 180° indicates a hydrophobic characteristic.)

 

Hydrophobic Patency

Our advanced HDPE water supply pipes offer an unparalleled smooth inner wall compared to conventional plastic pipes. This reduces flow resistance, enhances water transmission capacity, and improves the wall's smoothness beyond traditional polyethylene pipes. Designed specifically for the drinking water industry, these pipes efficiently solve the challenge of increased energy consumption in long-term pipe network operations.

Anti-bacterial Performance

Our innovative pipes incorporate an ionic antibacterial agent into their inner walls. As verified by the Guangdong Microbiological Analysis and Testing Center under the JC/T939-2004 standard for 'Antibacterial Performance of Antibacterial Plastic Pipe for Construction', our pipes demonstrate an outstanding antibacterial rate of over 99.99% against Escherichia coli and Staphylococcus aureus (standard testing bacteria). This ensures the elimination of microorganisms on the tube wall, prevents microbial film growth, and provides a lasting antibacterial effect.

Terrain Adaptability

Our pipes are designed with flexibility in mind, allowing them to adapt effortlessly to varying terrains under pressure. This flexibility reduces the need for additional fittings and accommodates terrain changes when settling occurs.

 

Economical and Efficient

Our HDPE water supply pipes are notably lighter than concrete, galvanized, or steel pipes, simplifying handling and installation. The reduced manpower and equipment requirements lead to significantly lower installation costs, making them an economical choice for any project.

Long Service Life
Crafted from high-quality polyethylene material, our pipes boast a commendable long-term design life, with an extrapolated service life reaching up to 50 years under standard working conditions.
