Extended data
Aluminum pipe is a kind of hard aluminum with high strength, which can be strengthened by heat treatment. Moderate plasticity during annealing, just quenched and hot, good spot welding. When gas welding and argon arc welding are used, intergranular cracks are easy to form in aluminum pipes. The machinability of aluminum tube after quenching and cold working hardening is still good, but it is not good in annealed state. Corrosion resistance is not high, so the surface is often anodized and painted or aluminized to improve corrosion resistance. It can also be used as a mold material.
The advantage of aluminum pipe is the advantage of welding technology: the welding technology of thin-walled copper-aluminum pipe suitable for industrial production is called a world-class problem, and it is the key technology to replace copper with aluminum for air conditioning connecting pipes. Secondly, the advantage of service life: from the inner wall of aluminum pipe, because the refrigerant does not contain water, the inner wall of copper-aluminum connecting pipe will not be corroded. Finally, it has excellent bending performance and is easy to install and move.
