Aluminum pipes are mainly divided into the following types
Divided by appearance: square pipe, round pipe, pattern pipe, special shape pipe, global aluminum pipe.
According to the extrusion method: seamless aluminum tube and ordinary extrusion tube
Divided by accuracy: ordinary aluminum tube and precision aluminum tube, the precision aluminum tube generally needs to be reprocessed after extrusion, such as cold drawing, rolling.
Divided by thickness: ordinary aluminum tube and thin wall aluminum tube
Performance: Corrosion resistance, light weight.
characteristic
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. When using gas welding and argon arc welding, aluminum tube has the tendency to form intergranular cracks; The machinability of aluminum tube is good after quenching and cold hardening, but bad when annealed. Corrosion resistance is not high, often using anodic oxidation treatment and paint method or surface coated with aluminum layer to improve the corrosion resistance. It can also be used as a mold material.
Advantages of aluminum tube: one is 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 pipe aluminum instead of copper.
Second, the service life advantage: from the inner wall of the aluminum tube, because the refrigerant does not contain moisture, the inner wall of the copper aluminum connection tube will not corrode.
Three is energy-saving advantage: air conditioner indoor unit and outdoor unit connection pipeline, the lower the heat transfer efficiency, the more energy saving, or, the better the heat insulation effect, the more power saving.
Four is excellent bending performance, easy to install, move
