Aluminum tubing is a kind of non-ferrous metal pipe, which is made of pure aluminum or aluminum alloy and extruded into a hollow metal tube along its longitudinal length. Aluminum tube is a kind of high strength duralumin, which can be strengthened by heat treatment. It has medium plasticity in annealing, quenching and hot state, and has good spot welding property. When gas welding and argon arc welding are used, aluminum tube tends to form intergranular cracks. After quenching and cold work hardening, the machinability of aluminum tube is good, but it is poor in annealed state. Because of its low corrosion resistance, anodizing and painting methods or adding aluminum coating on the surface are often used to improve the corrosion resistance. It can also be used as mold material. I will show you some basic information of the aluminum tubing in this article.

Detailed introduction of the aluminum tubes
Aluminum tube is a kind of pipe material which is popular on the market now. It is light, durable and easy to construct. It is also more suitable for use in home decoration. The main drawback of aluminum pipes is that when it is used as hot water pipe, the long-term thermal expansion and cold contraction will cause the wall dislocation of aluminum pipe, resulting in leakage. The inner and outer layers of aluminum tube are made of special polyethylene material, which is clean, nontoxic and smooth. It can be used for more than 50 years. Polyethylene is a non-toxic, odorless plastic, with good impact resistance, corrosion resistance, weather resistance. The longitudinal welding of aluminum alloy in the intermediate layer makes the aluminum pipes have the pressure resistance strength of metal, the impact resistance ability makes the pipe easy to bend and does not rebound. The aluminum tubing has the characteristics of strong pressure resistance of metal pipe, which is the model of the new generation of pipe material.
What is the characteristics of the aluminum pipes?
Aluminum tube has many advantages. The following four points are briefly introduced.
1. First, welding technology advantages: the welding technology of thin-walled copper aluminum pipe suitable for industrial production, known as the world-class problem, is the key technology of replacing copper with aluminum for connecting pipe of air conditioner.
2. The second is the advantage of service life: from the perspective of the inner wall of the aluminum tube, the inner wall of the copper aluminum connecting pipe will not be corroded because the refrigerant does not contain moisture.
3. Third, energy saving advantages: the connecting pipe between indoor unit and outdoor unit of air conditioner is aluminum tube. The lower the heat transfer efficiency, the more energy-saving, or in other words, the better the heat insulation effect, the more energy-saving.
4. Fourth, installation advantages: aluminum tubing bending performance is excellent, easy to install, move machine.
The structure of the aluminum tubing
The aluminum pipe is divided into five layers from the inside to the outside, which are PE plastic inner layer, inner adhesive layer, aluminum tube layer, outer adhesive layer and PE plastic outer layer. The middle aluminum layer is made of aluminum tubing welded by aluminum plate, and the inner and outer plastic layers are bonded together by adhesive. Therefore, the quality of aluminum pipe is related to the thickness of aluminum layer, welding technology and whether there is false welding, and also has relationship with the different materials used in the inner and outer layers and adhesives, and the quality is good or bad.
The above is the instruction of the aluminum pipes in detail.
