Aluminum pipe is a non-ferrous metal pipe, and it can be of one or more closed through-holes. Its wall thickness and cross-section must be uniform, which is basis of requirement for the aluminum production. Aluminum pipe is widely used in automobiles, ships, aerospace, aviation, electrical appliances, agriculture, electrical and mechanical, home and other industries.

Bellow, for a further understanding about aluminum pipe, there are some basic knowledge about it.

First, Classification

According to shape, there are: square pipe, circular pipe, pattern pipe, shaped pipe, global aluminum pipe.

According to extrusion, there are: seamless aluminum pipe and ordinary extruded pipe

According to precision, there are: ordinary aluminum pipe and precise aluminum pipe. And the precise aluminum pipe in general needs to re-process after extrusion, such as cold drawing and pumping in precise, and rolling.

According to thickness, there are: ordinary aluminum pipe and thin-walled aluminum pipe.

Second, Performance

Aluminum pipe is corrosion-resisted, and has light weight.




Third, Characteristic

As a high-strength hard aluminum, it can be heat-treated to strengthen. In annealing, just quenching and thermal status, the plasticity is medium. It has good performance of spot welding, but with gas welding and argon arc welding, the aluminum pipe has the tendency to form intergranular cracks. In quenching and cold-hardening, the cutting performance is still good, but it is bad in the annealed state. Corrosion resistance is not high, so in order to improve corrosion resistance, there are common methods, such as anodizing, painting or surface cladding aluminum layer. The aluminum can also be used as a mold material.

Forth, Advantage

1. The advantages of welding technology: thin-walled copper and aluminum pipe welding technology suitable for industrial production is known as world-class problems, and it is the key technology of air-conditioning connecting aluminum pipe.

2. The advantages of service life: in terms of the aluminum pipe wall, because the refrigerant does not contain water, the inner wall of aluminum connecting pipe will not be corroded.

3. Energy-saving advantages: for the connecting pipe between air conditioner indoor unit and outdoor unit, the lower the heating efficiency, the more energy-saving.

4. Aluminum pipe has excellent bending performance, and is easy to install, transfer machine

Fifth, Surface treatment

Chemical treatment: oxidation, electrophoretic coating, fluorocarbon spraying, powder coating, grain transfer

Mechanical treatment: mechanical drawing, mechanical polishing, sandblasting

Sixth, Use

Aluminum pipes are widely used in all walks of life, such as: automobiles, ships, aerospace, aviation, electrical appliances, agriculture, electrical and mechanical, home and so on. Aluminum pipes in our lives have been everywhere.
