The aluminum tube is a kind of high-strength hard aluminum that can be strengthened by heat treatment. It has medium plasticity under annealing, fresh quenching and hot conditions, and has good spot welding properties. The aluminum tube has a tendency to form intergranular cracks when gas welding and argon arc welding are used; The machinability of aluminum tubes is good after quenching and cold work hardening, but poor in the annealed state. The corrosion resistance is not high, and anodizing and painting methods are often used, or an aluminum layer is added to the surface to improve corrosion resistance. Can also be used as mold material.
Advantages of aluminum pipes: First, the advantages of welding technology: The welding technology of thin-walled copper and aluminum pipes suitable for industrial production is known as a world-class problem and is the key technology for replacing copper with aluminum in air conditioner connecting pipes.
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, corrosion will not occur on the inner wall of the copper-aluminum connecting tube.
The third is the energy-saving advantage: the lower the heat transfer efficiency of the connecting pipeline between the indoor unit and the outdoor unit of the air conditioner, the more energy-saving, or in other words, the better the heat insulation effect, the more energy-saving.
Fourth, it has excellent bending performance and is easy to install and move.
