Alminum tube is a type of non-ferrous metal tube, which refers to a metal tube like material that is extruded and processed into a hollow longitudinal length using pure aluminum or aluminum alloy.

classification

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

purpose

Aluminum tubes are widely used in various industries, such as automobiles, ships, aerospace, aviation, electrical appliances, agriculture, electromechanical, home, etc. Aluminum tubes are already ubiquitous in our lives.
