Product Description

In the realm of modern drinking water distribution, traditional pipelines like cement mortar ductile iron, plastic-coated steel, and PE pipes often encounter significant challenges. These include microbial growth, yellowing water due to pipeline corrosion, scaling on the inner walls, and reduced water transmission capacity. Such issues not only diminish the operational economy of the water network but also lead to 'secondary pollution,' resulting in non-compliant water quality at the user end.

Driven by the desire for enhanced living standards, Donghong Pipe Industry has leveraged over 20 years of expertise in the research and development of plastic composite pipelines. Addressing issues like 'secondary pollution' and reduced transmission capacities, Donghong has utilized its advanced know-how in functional material development, pipeline structural design, and specialized production processes. This has culminated in the creation of innovative composite pipeline products with superior antibacterial and anti-scaling properties, ensuring the intrinsic safety and reliability of drinking water networks.

Connection Method

1. Elctric fusion connection.

2. Butt fusion Connection.

3. Flange Buckle Connection

Product Features

Anti-scaling property

With inspiration drawn from the 'lotus leaf hydrophobic' principle, Shandong Donghong Pipe Industry Co., Ltd. employs cutting-edge organic polymers and specialized processes to elevate the water contact angle on pipeline surfaces to an impressive 111° (standard control ≥105°). This remarkable achievement surpasses the usual 88°-92° found in ordinary polyethylene, significantly enhancing the pipeline's surface smoothness. This innovation effectively reduces the adsorption capacity of calcium, magnesium ions, and other substances in water, thereby lowering the pipeline's energy consumption. Additionally, the synergistic effects of anti-scaling and antibacterial properties ensure a truly effective antibacterial performance, preventing the non-contact failure of the antibacterial layer with the fluid due to scaling issues. (Water contact Angle: Refers to the angle formed by a water droplet on a material's surface, with 90° < water contact Angle < 180° indicating hydrophobicity.)

Hydrophobic patency

Our pipes boast a smoother inner wall compared to conventional plastic options, offering reduced flow resistance and enhanced water transmission capabilities. This superior inner wall smoothness outshines traditional polyethylene pipes and directly addresses the increased energy consumption observed during prolonged operation in pipe networks. Designed specifically for the drinking water industry, these pipes ensure efficient and uninterrupted service.

Anti-bacterial Performance

Incorporating an ionic antibacterial agent within the pipe's inner wall, we have achieved remarkable antibacterial capabilities. Tested by the Guangdong Microbiological Analysis and Testing Center according to JC/T939-2004 standards, our pipes exhibit an astonishing antibacterial rate of > 99.99% against Escherichia coli and Staphylococcus aureus. This standard-compliant performance ensures the effective elimination of microorganisms attached to the tube wall, preventing microbial film formation and maintaining a permanent antibacterial effect.

Terrain adaptability

Our pipes are engineered with flexibility in mind, ensuring seamless performance even when under pressure. This adaptability allows for flexible laying that reduces the need for additional pipe fittings and accommodates terrain shifts and settlements effectively, making them ideal for varied landscapes.

Economical and efficient

Lightweight yet robust, our pipes outshine concrete, galvanized, and steel alternatives in ease of handling and installation. The reduced manpower and equipment requirements translate into significantly lower installation costs, offering a highly economical and efficient solution for any project.

Long Service Life
Crafted from durable polyethylene materials, our pipes promise a long-term design life. Their extrapolated service life extends to an impressive 50 years under normal working conditions, ensuring longevity and reliability.
