Q And A About Aluminium Pipe
What is the difference between aluminum alloy pipe and aluminum pipe?
Aluminum pipeand aluminum alloy pipe are more common metal pipes in daily life. You can distinguish between them because you know what they are and how they are used, but when they are put together, it will be hard to tell apart. In fact, when the aluminum pipe and the aluminum alloy pipe are put together, the vast majority cannot distinguish them. But from the perspective of the aluminum pipe supplier, aluminum pipe is a kind of high strength hard aluminum, which can be strengthened by heat treatment. Under the condition of annealing, quenching and heat, its plasticity is medium, and the spot welding property is good. When gas welding and argon arc welding are used, the aluminum pipe tends to form intergranular cracks. After quenching and cold work hardening, the machinability of aluminum pipe is good. In the annealed state, it is not good. Its corrosion resistance is not high, and anodizing and painting methods or aluminum coating are often used to improve its corrosion resistance. The density of aluminum alloy pipe is low, but the strength is relatively high, which is close to or exceeds that of high-quality steel. It has good plasticity and can be machined into all kinds of profiles. It has excellent conductivity, thermal conductivity and corrosion resistance, and has been widely used in industry, and is second only to steel. Aluminum alloy pipe can obtain good mechanical properties, physical properties and corrosion resistance by using thermal reserves.
What oil is used for deep drawing and stamping of aluminum pipe?
The chemical properties of aluminum elements are relatively active, easy to react with acid and alkali, resulting in corrosion, rust point, blackening, and mildew and so on. Aluminum material is widely used in automobile engine, transmission, aviation equipment and other mechanical equipment industry, so the demand for aluminum deep drawing and stamping oil is increasing day by day. Aluminum drawing and stamping oil products provide the good lubricity and cool ability required by high feed ratio and speed of aluminum pipe processing, which can prolong the service life. According to the above, the selection of aluminum and its alloy stamping and drawing oil is very important. What’s more, as for the aluminum pipe supplier, the good lubricity, cool ability, filtration and rust resistance must be guaranteed during production. Therefore, the stamping and drawing oil which can be used for aluminum and its alloy processing is different from the ordinary stamping and drawing oil, so it is very necessary to choose a suitable aluminum drawing pressing oil.
Why in production, aluminum pipe supplier generally does not recommend the use of laser pipe cutting machine to cut aluminum pipe?
First of all, as for cutting quality, aluminum profile is a high reflection material, so laser pipe cutting machine cannot process thicker aluminum. In addition, aluminum materials are resistant to high temperature and are prone to burr in the cutting process. Therefore, it is necessary to focus on the control of the process, otherwise it is difficult to cut the ideal cutting quality. Second of all, as for cutting speed, when cuttingaluminum pipe, cutting speed is too fast to produce burr, too slow cutting speed will make aluminum material crack. These factors will affect the quality of cutting, so special cutting process control is needed. Third of all, as for production cost, the processing cost of cutting aluminum pipe with laser tube cutting machine is very low, but because aluminum is a high reverse material, the laser damage to laser pipe cutting machine will greatly reduce the life of laser. Therefore, as far as the loss of the machine is concerned, the production cost of cutting aluminum pipe by laser pipe cutting machine is very high. From the above three points, we can see that if the laser pipe cutting machine is used to cut the aluminum pipe, not only the cutting effect is not ideal, but also the cutting efficiency is low, and the cost of consumables is high. Aluminum pipe supplier sincerely suggests that when cutting aluminum pipe, you can choose a special aluminum pipe cutting machine.
Why does deoiling aluminum pipe become distressing?
First, aluminum pipes can be seen everywhere in heavy industry materials, mechanical parts forging, metal welding materials and other industries. However, thealuminum pipe soaked in oil for a long time still exists after rust removal. Then rust, then remove oil, constantly cycle repeatedly, which greatly reduces the efficiency of the work. Second, because the aluminum pipe deoiling project is often the first step of appearance treatment. Stubborn oil pollution occurs corrosion phenomenon under the cleaning of traditional strong deoiling agent. Gently wash it, then after removing the oil, it is not clean. If you push too hard, things will be the opposite. So, as a professional aluminum pipe supplier, we advise you to choose the aluminum pipe cleaning agent with strong cleaning ability and excellent oxidation resistance, which is not easy to corrode and for the environmental protection and safety concern.
