There is one or more closed through holes, the thickness and cross section of the wall are uniform, and they can be delivered in a straight line or in a roll shape. It is widely used in automobiles, ships, spaceflight, aviation, electrical appliances, agriculture, mechanical and electrical, home and other industries.
Aluminum pipes are mainly divided into the following
According to the shape: square tube, round tube, pattern tube, special-shaped tube, universal aluminum tube.
Press mode: seamless aluminum tube and ordinary extrusion pipe
According to the precision: the ordinary aluminum tube and the precision aluminum tube, in which the precision aluminum tube usually needs to be reprocessed after the extrusion, such as the cold drawing and the rolling.
According to the thickness: ordinary aluminum tube and thin wall aluminum tube
Performance: corrosion resistance, light weight.
As a kind of high strength aluminum alloy, heat treatment can be strengthened, annealing, quenching and heat under the condition of rigid plasticity, good welding, gas welding and argon arc welding in aluminum has the tendency of intergranular crack formation; aluminum hardening in quenching and cold cutting performance is good and bad in annealing state when. The corrosion resistance is not high, in order to improve the corrosion resistance of anodic oxidation treatment and often used methods of paint or aluminum surface layer. It can also be used as a mold material.
Aluminum pipe advantages: first, the advantages of welding technology: thin walled copper and aluminum pipe welding technology suitable for industrial production, is known as the world-class problem, and is the key technology of aluminum connection for air conditioner connecting pipe.
Two is the use of life advantage: from the inner wall of the aluminum tube, the inner wall of the copper and aluminum connecting pipe will not be corroded because the refrigerant does not contain water.
The three is the energy saving advantage: the connecting line between the indoor and outdoor units of the air conditioner, the lower the heat transfer efficiency, the more energy saving, or the better the heat insulation effect.
Four is the bending performance, easy installation and removal
