Introduction of Aluminum Tube
Aluminum tube is a kind of non-ferrous metal tube, which refers to a metal tubular material that is hollow along its longitudinal length by extruding pure aluminum or aluminum alloy.
Aluminum tubes can have one or more closed through holes, uniform wall thickness and cross section, and are delivered in straight or roll shape. It is widely used in automobile, ship, aerospace, aviation, electrical appliances, agriculture, mechanical and electrical, home and other industries.
Classification of Aluminium Tube
According to the shape: square pipe, round pipe, pattern pipe, shaped pipe, global aluminum pipe.
According to the extrusion method: seamless aluminum tube and ordinary extrusion tube
According to the accuracy: ordinary aluminum tubes and precision aluminum tubes, of which precision aluminum tubes generally need to be reprocessed after extrusion, such as cold drawing and rolling.
According to the thickness: ordinary aluminum tube and thin-walled aluminum tube.
Property: Corrosion resistance, light weight.
Aluminum tube is a kind of high strength duralumin, which can be strengthened by heat treatment. It has medium plasticity under annealing, hardening and hot state, and good weldability in spot welding. Aluminum tube has a tendency to form intergranular cracks during gas welding and argon arc welding. The machinability of aluminum tube is good after quenching and cold hardening, but poor in annealing state. Corrosion resistance is not high, often using anodic oxidation treatment and painting method or surface coated with aluminum layer to improve the corrosion resistance. Can also be used as a mold material.
Surface treatment of Aluminum Tube
Chemical treatment: oxidation, electrophoretic coating, fluorine carbon spraying, powder spraying, wood grain transfer
Mechanical treatment: mechanical drawing, mechanical polishing, sandblasting
Advantages of Aluminum Tube
First , welding technology: suitable for industrial production of thin-wall copper aluminum pipe welding technology, known as a world-class problem, is the key technology of air conditioner connection pipe aluminum copper replacement.
Second , the service life: from the inner wall of the aluminum pipe, because the refrigerant does not contain moisture, the inner wall of the copper and aluminum connection pipe will not corrod.
Third , 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.
