Aluminum pipes are mainly divided into the following types

Divided by shape: square pipe, round pipe, pattern pipe, shaped pipe, global aluminum pipe.

According to the extrusion method: seamless aluminum tube and ordinary extrusion tube

Divided by 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.

Divided by thickness: ordinary aluminum tube and thin-walled aluminum tube

Performance: Corrosion resistance, light weight.

peculiarity

It is a kind of high strength duralumin, which can be strengthened by heat treatment, has medium plasticity under annealing, hardening and hot state, and has good spot welding weldability. Aluminum tubes have 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.

Advantages of aluminum pipe: First, welding technology advantages: 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 advantage: 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.

The third is energy-saving advantage: 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

Surface treatment

Chemical treatment: oxidation, electrophoretic coating, fluorine carbon spraying, powder spraying, wood grain transfer

Mechanical treatment: mechanical drawing, mechanical polishing, sandblasting

use

Aluminum tubes are widely used in all walks of life, such as: automobiles, ships, aerospace, aviation, electrical appliances, agriculture, electrical, home, etc., aluminum tubes are everywhere in our lives.
