Aluminum Tube

Aluminum pipes are mainly divided into the following types
Divided by appearance: square tube, circular tube, patterned tube, irregular tube, and universal aluminum tube.
Divided by extrusion method: seamless aluminum pipe and ordinary extrusion pipe
According to precision, it is divided into ordinary aluminum pipes and precision aluminum pipes. Precision aluminum pipes generally need to be processed after extrusion, such as cold drawing, precision drawing, and rolling
Divided by thickness: ordinary aluminum pipe and thin-walled aluminum pipe
Performance: Corrosion resistant, lightweight.
characteristic
It is a high-strength hard aluminum that can undergo heat treatment and strengthening. It has moderate plasticity under annealing, hard quenching, and hot conditions, and good spot welding weldability. When using gas welding and argon arc welding, aluminum pipes tend to form intergranular cracks; After quenching and cold work hardening, the machinability of aluminum pipes is still good, but it is poor in the annealed state. The corrosion resistance is not high, and anodizing and painting methods or adding an aluminum coating on the surface are often used to improve the corrosion resistance. It can also be used as a mold material.
Advantages of aluminum pipes: Firstly, welding technology advantages: The welding technology of thin-walled copper aluminum pipes suitable for industrial production, known as a world-class problem, is a key technology for replacing copper with aluminum in the connecting pipes of air conditioners.
Secondly, the advantage of service life: From the perspective of the inner wall of the aluminum tube, due to the absence of moisture in the refrigerant, the inner wall of the copper aluminum connecting tube will not undergo corrosion.
The third advantage is energy-saving: the lower the heat transfer efficiency of the connecting pipeline between the indoor and outdoor units of the air conditioner, the more energy-saving it is, or in other words, the better the insulation effect, the more energy-saving it is.
The fourth is excellent bending performance, easy to install and move
