Aluminum pipe is a kind of non-ferrous metal pipe, refers to pure aluminum or aluminum alloy by extrusion processing along its longitudinal length hollow metal tube material.
Aluminum tubes may have one or more closed through holes, uniform wall thickness and cross section, and are delivered in straight line or in roll. Widely used in automobile, ship, aerospace, aviation, electrical appliances, agriculture, mechanical and electrical, home and other industries.
Aluminum tubes are mainly divided into the following types
According to the shape: square pipe, round pipe, decorative pipe, special pipe, global aluminum pipe.
According to extrusion: seamless aluminum pipe and ordinary extrusion pipe
According to the precision: ordinary aluminum tube and precision aluminum tube, precision aluminum tube generally need to be reprocessed after extrusion, such as cold drawing fine pumping, rolling.
According to the thickness: ordinary aluminum tube and thin wall aluminum tube
Performance: corrosion resistance, light weight.
Characteristics of aluminum tube
It is a kind of high strength hard aluminum, which can be strengthened by heat treatment. It has medium plasticity under annealing, rigid quenching and heat state, and good spot welding weldability. It has the tendency to form intercrystalline cracks when using gas welding and argon arc welding. The machinability of aluminum tube is good after quenching and cold hardening, but bad in annealing state. Corrosion resistance is not high, often use anodic oxidation treatment and coating method or surface coated aluminum layer to improve corrosion resistance. It can also be used as mold material.
Advantages of aluminum tube:
First, the advantages of welding technology: thin-wall copper and aluminum tube welding technology suitable for industrial production, known as a world-class problem, is the key technology of air conditioner connecting tube aluminum instead of copper.
Second, the service life advantage: from the perspective of the inner wall of the aluminum tube, because the refrigerant does not contain moisture, the inner wall of the copper and aluminum connection tube will not occur corrosion phenomenon.
Three, energy-saving advantages: 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 insulation effect, the more electricity saving.
Four, is good bending performance, easy to install, move machine
The surface treatment of aluminum tube is divided into:
Chemical treatment: oxidation, electrophoretic coating, fluorine carbon spraying, powder spraying, wood grain transfer printing
Mechanical treatment: mechanical drawing, mechanical polishing, sandblasting
Use of aluminum tube
Aluminum tubes are widely used in many fields because of their unique physical and chemical properties. The following are some common uses of aluminum tubes:
1. Construction field: aluminum tube is used to make doors and Windows, curtain walls, ceilings, partitions, stair handrails, etc. It is lighter, corrosion resistant and easy to process than traditional steel or wood. Aluminum tubes also have good surface treatment properties, which can improve decorative and durability through technologies such as anodic oxidation spraying.
2. Automobile manufacturing: In the automobile industry, aluminum tubes are used in the production of key components such as body, engine, and chassis. Compared to steel, aluminum can reduce vehicle weight, improve fuel efficiency and driving performance.
3. Aerospace: Aluminum tubes also have important applications in aerospace, where they are used to manufacture aircraft, rockets, satellites and other components. Its light weight and high strength help to reduce the total weight of the vehicle while improving the load capacity and flight performance.
4. Electronic appliances: aluminum tubes are also widely used in the manufacturing of electronic products, such as radiators, battery shells, wire tubes, etc. It provides good thermal conductivity and corrosion resistance, which helps to improve the performance and lifetime of electronic devices.
5. Packaging: aluminum tubes are used for high-quality packaging of cosmetics, pharmaceuticals, food and other products. Compared with plastic and glass pipes, aluminum pipes have better sealing performance and corrosion resistance, which is conducive to protecting product quality and safety.
6. Household appliances: Aluminum tubes are also used in the manufacturing of household appliances, including refrigerators, washing machines, and other equipment, as they require a material that is light, durable, and easy to process.
7. Chemical industry: aluminum pipe is used to transport acid, alkali, salt and other corrosive chemicals, as well as used as a lining in chemical reaction kettle, pipeline and other equipment.
8. Food and pharmaceutical field: due to the corrosion resistance and hygiene of aluminum tubes
With the continuous progress and development of science and technology, the application of aluminum tube has been everywhere, people more or less have a certain understanding of it, if you just need, please contact us!
