Aluminum Tube Classification

Aluminum tubes are mainly divided into the following categories
According to the shape: square tube, round tube, pattern tube, special-shaped tube, global aluminum tube.
Divided by extrusion method: seamless aluminum tube and ordinary extruded tube
According to the accuracy, it is divided into ordinary aluminum tubes and precision aluminum tubes. Among them, precision aluminum tubes generally need to be reprocessed after extrusion, such as cold drawing and precision drawing and rolling.
According to thickness: ordinary aluminum tube and thin-walled aluminum tube
Properties: Corrosion resistance, light weight.
characteristic
It is a kind of high-strength hard aluminum, which can be strengthened by heat treatment. It has medium plasticity under annealing, just quenching and hot state, and has good spot welding weldability. When gas welding and argon arc welding are used, the aluminum tube has a tendency to form intergranular cracks; The machinability is good after quenching and cold work hardening, but poor in the annealed state. The corrosion resistance is not high, and anodizing treatment and painting methods are often used or the surface is coated with aluminum layer to improve the corrosion resistance. Can also be used as mold material.
Advantages of aluminum tubes: First, the advantages of welding technology: the welding technology of thin-walled copper-aluminum tubes suitable for industrial production is known as a world-class problem and is the key technology for replacing copper with aluminum for connecting tubes of air conditioners.
The second is the advantage of service life: from the perspective of the inner wall of the aluminum tube, since the refrigerant does not contain moisture, the inner wall of the copper-aluminum connecting tube will not corrode.
The third is the advantage of energy saving: the connection pipeline between the indoor unit and the outdoor unit of the air conditioner, the lower the heat transfer efficiency, the more energy saving, or the better the heat insulation effect, the more power saving.
Fourth, excellent bending performance, easy to install and move
