Introducing Shandong Donghong Pipe Industry Co., Ltd.

Our company offers a range of high-quality drinking water pipes designed to address common issues found in existing pipelines. Our pipes are made from durable materials such as cement mortar ductile iron, plastic-coated steel, and PE, ensuring longevity and reliability.

By using our pipes, you can say goodbye to problems like microbial breeding, yellow water due to corrosion, scaling on the inner walls, and reduced water transmission capacity. This not only improves the efficiency of your network but also prevents "secondary pollution" that can affect water quality for end-users

Choose Shandong Donghong Pipe Industry Co., Ltd. for superior water pipes that prioritize performance and safety.

Introducing Shandong Donghong Pipe Industry Co., Ltd.

With over 20 years of expertise in research, development, and manufacturing of plastic composite pipelines, Donghong shares a commitment to enhancing people's quality of life. By addressing issues like "secondary pollution" and transmission capacity, our special composite pipeline products boast anti-bacterial and anti-scaling functions. Through innovative technologies in functional material development, pipeline structural design, and special processes, we ensure the intrinsic safety of drinking water networks.

Anti-scaling property

Drawing on the principle of "lotus leaf hydrophobic", organic polymers and special processes are used to raise the water contact Angle on the surface of the pipeline to 111° (standard control ≥105°), far exceeding ordinary polyethylene 88°-92°, which improves the smoothness of the surface of the pipeline, reduces the adsorption capacity of calcium and magnesium ions and other substances in the water to the pipeline, and reduces the energy consumption of the pipeline water. At the same time, the anti-scaling effect and the antibacterial effect of the pipeline cooperate to play the role of the real antibacterial effect of the pipeline, and avoid the problem of non-contact failure between the antibacterial layer and the fluid caused by pipeline scaling. (Water contact Angle: the contact Angle of water droplets on the surface of the material, 90° < water contact Angle < 180° has a hydrophobic effect.)

Hydrophobic patency

Compared with conventional plastic pipes, the inner wall is smoother, the flow resistance is reduced, the water transmission capacity is higher, and the inner wall smoothness is better than that of traditional polyethylene pipes, solving the problem of increased energy consumption in long-term operation of the pipe network, and it is a pipeline type designed for the drinking water industry.

Anti-bacterial Performance

The ionic antibacterial agent was added to the inner wall of the pipe. According to the standard of JC/T939-2004 "Antibacterial performance of antibacterial plastic pipe for Construction" tested by Guangdong Microbiological Analysis and Testing Center, the antibacterial rate of the component was > 99.99% against Escherichia coli and Staphylococcus aureus (standard requirements for testing bacteria); It can eliminate microorganisms attached to the tube wall, avoid the breeding of surface microbial film, and has a permanent antibacterial effect.

Terrain adaptability

When the pipe is under pressure, the flexibility of the plastic pipe is taken into account. The flexible laying can reduce the application of pipe fittings and change with the terrain when the terrain settles.

Economical and efficient

The pipe is lighter than the concrete pipe, galvanized pipe and steel pipe, easy to handle and install , and the lower manpower and equipment requirements mean that the installation cost of the project is greatly reduced.

Long Service Life
Polyethylene pipe material has a long-term design life, and the extrapolated service life of the pipe under normal working conditions is 50 years.
