Product Description
Aluminum tubes are mainly divided into the following types
Divided by shape: square tube, round tube, pattern tube, shaped tube, global aluminum tube.
According to the extrusion method: seamless aluminum tube and ordinary extrusion tube
According to accuracy: ordinary aluminum tube and precision aluminum tube, in which precision aluminum tube generally need to be reprocessed after extrusion, such as cold drawing, fine pumping, rolling.
By thickness: ordinary aluminum tube and thin wall aluminum tube
Performance: corrosion resistance, light weight.
Features
It is a kind of high strength duralumin, which can be strengthened by heat treatment. It has medium plasticity in annealing, hardening and hot state, and good weldability in spot welding. It tends to form intercrystalline cracks in gas welding and argon welding. The machinability of aluminum tube is good after quenching and cold work hardening, but poor in annealing state. Corrosion resistance is not high, often using anodic oxidation treatment and paint method or surface coated with aluminum layer to improve corrosion resistance. It can also be used as a mold material.
Aluminum tube advantages: first, welding technology advantages: suitable for industrial production of thin-wall copper aluminum tube welding technology, known as a world-class problem, is the key technology of air conditioner connecting tube aluminum copper.
Second, the service life advantage: from the inner wall of the aluminum tube, because the refrigerant does not contain water, the inner wall of the copper and aluminum connecting pipe will not corrode.
Three is the advantage of energy saving: the connection pipe of the indoor unit and outdoor unit of the air conditioner, the lower the heat transfer efficiency is, the more energy saving, or the better the heat insulation effect is, the more electricity saving.
Four is excellent bending performance, easy to install, move
Chemical treatment: oxidation, electrophoretic coating, fluorocarbon spraying, powder spraying, wood grain transfer printing
Mechanical treatment: mechanical drawing, mechanical polishing, sand blasting
