When seeing the water pipes of full of beautiful things in eyes on the market, whether can you hesitate how should you buy? Is to buy plastic water pipes or copper ones? What are the pros and cons of each? If you are not a professional pipe manufacturer like us, it is difficult to tell which is best for you. Don't worry! We have this guide ready for you.


Here is the content list:

1) Advantages of Copper Water Pipes

2) Advantages of Plastic Water Pipes

3) Copper Water Pipes VS Plastic Water Pipes


Advantages of Copper Water Pipes

Copper pipe has a long history of being used as water supply pipe. In developed countries, copper water pipes system has very large proportion. The application technology of cupreous water pipes is in abroad already very mature, should extensive. Copper pipe’s fitting standards are complete, with diverse interface.

Copper has super antimicrobial properties, and can kill including candida albicans, e. coli, legionella bacteria and a variety of other bacteria. What’s more, copper ions can prevent cell respiration, punching or destroy the virus shell on bacterial cell membranes, and internal damage DNA and RNA, make its death, ensured the cleanness of drinking water hygiene, avoid secondary pollution.

Cupreous water pipes organize a structure extremely compact, be it grease, bacterium, virus, oxygen and ultraviolet ray cannot pass through it and pollute water quality.


Advantages of Plastic Water Pipes

Plastic water pipe generally uses synthetic resin as raw material, adding stabilizer, lubricant, plasticizer, to plastic method in the pipe machine by extrusion processing.

Because plastic water pipes have the characteristics of light weight, corrosion resistance, beautiful appearance, easy processing and convenient construction, they have been applied more and more widely in construction projects. Plastic water pipes are mainly used for water supply system distribution, drainage, exhaust and sewage sanitary pipes, underground drainage pipe system, rain water pipes and threading pipes for electrical wiring installation.

1. Light weight

The relative density of plastic water pipe is only 1/7 of cast iron, therefore, the transportation cost of plastic water pipe and the labor intensity of construction is greatly reduced.

2. Good corrosion resistance

Plastic water pipes were first used in chemical buildings, which are suitable for transporting corrosive liquids and gases without corrosion, reducing maintenance costs and having a long service life. According to foreign reports, the life expectancy of rigid PVC can be as long as 50 years.

3. Smooth wall

The fluid flow resistance is small, under the same condition, the plastic water pipe flow momentum is 30% higher than the copper water pipe.

4. Energy conservation

Compared with copper tube, plastic processing molding temperature is lower, so processing energy consumption is low. According to statistics, the energy saving effect of rigid PVC water pipe reaches more than 50%.

5. Reasonable price

According to the actual construction and installation statistics, the material cost can be reduced by 20% by using the drainage system of rigid PVC water pipes.

Copper Water Pipes VS Plastic Water Pipes

Copper pipe interface has the production way of card sleeve and welding. The problem of aging and leakage exists in the sleeve for a long time, so most users who install copper pipes adopt welding, so as to be able to be the same as PPR plastic water pipes and never leak.

One disadvantage of copper pipe is that it conducts heat quickly, so the hot water pipes made by famous copper pipe manufacturers are covered with plastic and foaming agents.

Another drawback of copper pipe is the price is expensive, the water supply system of very few communities is copper pipe, it is plastic water pipes basically is used. If you plan to change the water pipe, and think the copper pipe is good, it is recommended to use welding interface.

The HDPE water pipe is connected by hot melt technology, and the pipes are completely fused together. Therefore, once the installation pressure test passes, there will be no aging water leakage like the aluminum-plastic pipe, and the HDPE water pipe will not scale.

In addition, the research and use of antibacterial plastics have become a trend to ensure that people can prevent the cross transmission of pathogenic microorganisms when they use HDPE water pipes and other plastic water pipes in large quantities. In recent years, anti-bacteria plastics have been widely used in the field of transporting drinking water due to its unique advantages. It is known that antibacterial plastic itself has antibacterial properties, can kill or inhibit bacteria stains on the plastic in a certain period of time. Moreover, compared with conventional chemical and physical methods, antibacterial plastics have a longer bactericidal time. It seems that the antibacterial properties of plastic water pipes are not weaker than copper pipes.


To sum up, we recommend you to choose plastic water pipes, especially HDPE water pipes. All our products are designed to meet the latest European standards, providing you with the highest quality, industry-leading pipes.
