What brand of aluminum plastic pipe brand is good, and the advantages and disadvantages of aluminum

Which brand of copper and aluminum pipes for air conditioners is better?

1. Advantages of aluminum-plastic pipes:

Aluminum-plastic pipes are lightweight, durable and easy to construct, and their bendability is more suitable for use in home decoration. The inner and outer layers of the aluminum-plastic pipe are made of special polyethylene material, which is clean, non-toxic, smooth, and can be used for more than 50 years. The middle aluminium layer is 100% insulated from gas permeation and gives the tube the advantages of both metal and plastic pipes.

Second, the main disadvantages of aluminum-plastic pipes:

When the aluminum-plastic pipe is used as a hot water pipe, due to long-term thermal expansion and contraction, the pipe wall will be misaligned and cause leakage.

Identification of aluminum-plastic pipes

Randomly select a section of aluminum-plastic composite pipe, hit it with something relatively hard, the pipe surface will be bent, if it is deformed to crack, it is inferior; If the deformed surface cannot be restored, it is a general texture; After deformation, it can be restored to its original shape immediately, and it is a high-quality aluminum-plastic pipe.

The color of high-quality aluminum-plastic pipe is uniform, there is no color difference, and the roundness is less than; The middle aluminum layer has a tight interface and no rough traces; The inner and outer surfaces are smooth and smooth, and there can be no obvious scratches, depressions, bubbles, dead materials, and buslines.

Take a section of aluminum-plastic pipe squared and cut it vertically, and put your fingers into the pipe, the nozzle of the high-quality pipe is smooth and there is no feeling of texture; The nozzle has no burrs.

1. The aluminum-plastic pipe produced by Netcom Pipe Industry is connected in the same way as PPR pipe, no need to peel the skin during installation, and it is connected with PPR pipe fittings of the same material for hot melt connection, which is firmly connected without leakage, ensuring the integration of pipes and pipe fittings.

2. Aluminum-plastic pipe is resistant to high temperature, high pressure and low temperature. It is mainly used for hot water pipes, and will not cause the problem of pipe wall dislocation and water pipe leakage due to long-term use.

3. Outstanding health performance, the inner and outer materials of the aluminum-plastic pipe, environmentally friendly and non-toxic, in line with the requirements of human health, the aluminum layer in the middle can not only block light, but also block oxygen. As we all know, endophytic microorganisms must have light and aerobic, and the middle aluminum layer of the aluminum-plastic pipe can prevent the breeding of microorganisms and algae plants, and will not produce scale.

4. Long service life, the innovative aluminum-plastic pipe of Netcom pipe industry belongs to the oxygen barrier pipe, the aluminum layer blocks oxygen, the sun protection prevents the water pipe from aging, and the service life in the outdoor is higher than that of other pipes, the light sealing performance is good, the reasonable use, and the pipe is more than 50 years.

The long-term working temperature should not exceed 110 °C; The length of each section is limited, and it can be slightly bent, but not excessively bent for construction; It is mainly used as a hot water pipe, and it is used as a cold water pipe. The production process of aluminum-plastic pipe is better than that of PPR all-plastic pipe, and the price is slightly higher.

We all know the importance of aluminum-plastic pipes for our daily life, but now there are many brands on the market, and recently people often ask how about aluminum-plastic pipes and the price of aluminum-plastic pipes.

How about aluminum-plastic pipes.

2. Excellent high and low temperature resistance: long-term use temperature of 95 degrees (50 years, IMPA), maximum use temperature of 110 degrees, and the thermal expansion coefficient of aluminum-plastic pipe is small. It is comparable to the thermal expansion coefficient of aluminum, which is only one-sixth of that of all-plastic tubes.

When subject to temperature changes, the deformation is small, and the aluminum-plastic pipe is a flexible coil, and the pipe itself can digest a certain amount of deformation, which will not cause the thermal expansion and deformation of the pipeline system. However, the high and low temperature resistance of all-plastic pipes is relatively poor. The long-term use temperature of PPR is only 70 degrees (50 years, IMPA) and the maximum use temperature is 95 degrees.

At the same time, the expansion coefficient of PPR pipeline is larger, and when the external water temperature (hot and cold water) changes, there is a large amount of original deformation, because the PPR pipe is a rigid straight pipe, it cannot digest the deformation, so it is easy to cause the system to bend and deform and even leak.

Third, different brands are different. The processing technology and raw materials of each company are different, and they are also very different. There are many small workshops that produce products that are several times different from the products of regular manufacturers.

If you need it, you can simply understand the relevant information through this article, so that you can better choose the products you like.

Aluminum-plastic pipe belongs to a kind of pipe, this kind of pipe is divided into five layers, the middle layer is aluminum, the inner and outer layers are made of plastic, the inner and outer layers are closely combined with the middle layer through adhesives, and have the advantages of strong pressure resistance, corrosion resistance, clean and non-toxic, light weight, long service life, impact resistance, good high and low temperature resistance, and good toughness. However, this kind of pipe also has shortcomings, for example, when the aluminum-plastic pipe is used as a hot water pipe, the pipe wall may be misaligned due to thermal expansion and cold contraction.
