Product Description

The existing drinking water pipes are mainly cement mortar ductile iron pipe, plastic coating steel pipe, PE pipe, in the application appears microbial breeding, yellow water (pipeline corrosion), inner wall scaling, pipe network water transmission capacity reduction and other problems, resulting in the reduction of the network operating economy at the same time the formation of water source "secondary pollution" caused by the user side of the network, the water quality unqualified.

Combined with the needs of people's aspirations for a better l ife, to solve the exi sting pipel ine network caused by "secondary pollution" and reduce the transmi ss ion capacity and other i ssues , Donghong shares combined with more than 20 years of experience in resear ch and development and manufacturing of plastic compos ite pipel ines , with the help of the company's functional material development, pipel ine struc tural des ign, the development of special processes , and other technologies to successfully develop special compos ite pipel ine produc ts with anti-bacterial and anti- s cal ing function, so that drinking water pipeline network to achieve the intrinsic safety.
Connection Method




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.
