The use of drinking water pipes has brought great convenience to our life. However, just like a coin with two sides, some of them can bring harm to human body. Fortunately, with the development of technology, more and more safe pipes have been developed, such as HDPE water pipes for drinking water. For the health of you and your customers, be sure to identify which pipes are not suitable for drinking water.


Here is the content list:

1) Why These Pipes Shouldn’t Be Used for Drinking Water?

2) Which Pipes Can Be Used for Drinking Water?

3) Why Should HDPE Pipes Be Used for Drinking Water?


Why These Pipes Shouldn't Be Used for Drinking Water?

Drinking water from the waterworks is transported by long drinking water pipes to be used by customers. In this long transportation process, it is likely to encounter the accumulation of sediment in the pipeline, transportation pipeline rust aging, bacterial breeding and other secondary pollution. Due to direct contact with drinking water, if the quality of drinking water pipes is not pass, it may become a health hazard, causing drinking water safety crisis, so the quality of drinking water pipes has strict standards.

However, in order to compete at a lower price, some enterprises have adopted the secondary recycled materials that are harmful to human health -chemical waste, medical waste, waste wire skin and other recycled materials that are crushed and used have serious safety problems. At the same time, plasticizer and other substances need to be added in the processing of plastic drinking water pipes, which will cause great harm to the user's body when mixed into the pipes.


Which Pipes Can Be Used for Drinking Water?

With the continuous improvement of urban economy and life, the requirements for urban water supply network are becoming higher and higher. The kind of conduit basically has PPR water pipe, aluminum plastic tube, HDPE water pipe to wait for a few kinds.

1) PPR water pipes

Compared with the traditional cast iron pipe, galvanized steel pipe, cement pipe and other pipes, PPR water pipe has the advantages of energy saving, environmental protection, light weight, high strength, corrosion resistance, smooth inner wall and no scaling, simple construction and maintenance, long service life and so on.

PPR water pipes are widely used in building water supply and drainage, urban and rural water supply and drainage, urban gas, industrial fluid transportation, agricultural irrigation and other fields. There is no doubt that the work of transporting drinking water is also involved.

2) Aluminum plastic tubes

Aluminum-plastic pipe is a new type of drinking water pipe composed of middle longitudinal welded aluminum pipe, inner and outer layers of polyethylene plastic and hot-melt glue co-extruded between layers. Polyethylene is a non-toxic and odor-free plastic with good impact, corrosion and weather resistance. The middle layer of longitudinal welding aluminum alloy drinking water pipe with metal compressive strength, impact resistance ability to make the pipe easy to bend and not rebound. Aluminum-plastic drinking water pipe has strong pressure resistance and plastic pipe acid-alkali corrosion resistance of the two major characteristics, which is a new generation of pipe model.

3) HDPE water pipes

In China's municipal pipe market, plastic pipe industry is developing steadily. HDPE water pipes, PPR water pipes, UPVC pipes have a place, but the HDPE water pipes strong development momentum is the most remarkable. HDPE water pipe is widely used in many fields, among which water supply pipe and gas pipe are the two largest application markets.


Why Should HDPE Pipes Be Used for Drinking Water?

A good pipeline should not only have a good economy, but also should have a stable and reliable interface, material impact resistance, anti-cracking, aging resistance, corrosion resistance and other abilities. Compared with traditional pipe, HDPE water pipe system has the following series of advantages:

1. Reliable connection

Polyethylene pipe systems are connected by electric hot melt, and the strength of joints is higher than that of HDPE water pipes.

2. Impact resistance

The low temperature embrittlement temperature of polyethylene is very low and can be used safely in the temperature range of -60-60℃. During winter construction, HDPE water pipes have good impact resistance, preventing drinking water pipes from brittle cracking.

3. Chemical resistance

HDPE water pipes are resistant to corrosion by a variety of chemical media, and the presence of chemical substances in the soil will not cause any degradation of the pipes. Polyethylene is an electrical insulator and therefore does not decay, rust or electrochemical corrosion. Nor does it promote the growth of algae, bacteria or fungi.

4. Low flow resistance

HDPE water pipes have smooth inner surfaces with a manning coefficient of 0.009. Smooth performance and non-adhesion characteristics ensure that HDPE water pipes have higher drinking water delivery capacity than traditional pipes, and at the same time reduce pressure loss and energy consumption of the pipelines.


As the characteristic product of our company, HDPE water pipes adopt the latest advanced technology of our company. After a long time of research by the professional team, they are finally developed successfully.

Eagle Machinery Co.,Ltd promise to provide you with the best quality and safe drinking water pipes. If you want to cooperate with us, we welcome you at any time.
