Aluminium tube is a kind of non-ferrous metal pipe, aluminum or aluminum alloy extrusion process along its full length vertical hollow metal tubular material. Can have one or more closed-hole, uniform wall thickness, cross-sectional, shaped or rolled up in a straight line of delivery. Widely used in automobile, ship, space, aviation, electrical, agricultural, electrical, household and other industries.
As a high-strength aluminum, heat, annealing, quenching and heat under medium plasticity, good spot welding, gas welding and argon arc welding of aluminum tube formed of intergranular crack inclination aluminum pipe in quench after hardening and cold cutting performance is good, bad in annealed State. Corrosion resistance is not high, anodized and painted is often used method or surface layers of aluminum to improve corrosion resistance. Can also be used as a mold material.
Aluminum tube advantages: welding technology advantages: suitable for welding technology of industrialized production of thin-walled copper tubes, known as the world's toughest problems, is the key technology of air conditioner pipe aluminum in place of copper.
Second life advantage: from aluminium tube, because the refrigerant does not contain water, copper and aluminum tube walls corrosion does not occur.
Third, energy-saving advantage: split air conditioner indoor unit and outdoor unit connection line, energy-saving heat as low as possible, or that the heat insulation as well as possible saving.
