Q:Will the size of the aluminum tube become smaller after oxidation?
Of course, the oxidation will become smaller, the oxidation time to be washed by alkali, aluminum meets alkali will react chemically, some of the aluminum will be dissolved. When the aluminum extrusions are extruded before oxidation, the allowance should be included. If the finished product is aluminum rod 10mm its tolerance is +0.10mm, if you need an oxidation in the extrusion, the time should be under the control of the product median +0.02mm is 10.07, the oxidation is 10.05 aluminum rods, of course also need to consider the need to straighten out after the extrusion process, will pull a few small silk. If you really need multiple oxidation, as you say, to shrink 0.06mm, then the size should be controlled after extrusion: the median value of the product is +0.06mm.
Q:1.2mm thickness of the aluminum tube, why measured only 1.0mm thick?
There is an error relationship, and may be affected by the environment, as well as the physical properties of the material itself, such as thermal expansion, cold contraction and so on
Q:Can aluminum tube and aluminium plate be welded? Fifty
Yes, it can be done. AC arc welding is OK, but only a professional master can do it.There is oxygen welding, and all need a very professional, not a casual city.
Q:Do I need special work permit for cutting aluminum tubes?
A special job job scope: 1, electrical operation 2, metal welding cutting operation 3, lifting machinery (including elevator), operating 4 motor vehicles in 5, driving high erection and high-altitude hanging industry 6, refrigeration task 7, boiler operation (including water quality test) 8, pressure vessel operation 9, blasting operations 10, mine operations (including gas inspection) 11.
Q:An aluminum tube, about 3 meters long, 5 cm in diameter, what is the price?
Would you like to know how large and thick the aluminum tube you are talking about, and the 6061 material is generally 24 yuan a kilogram
Q:The cooling tube is iron or aluminum Frestech refrigerator?
The refrigerator before 2000 there are many brands with a brass, later because of technological progress, aluminum air tightness and thermal conductivity reached the requirements of the refrigerator, and the copper price is very low, tens of thousands of dollars a ton of aluminum barrel, only thousands of dollars a ton, so now is to do with the refrigerator evaporator tubes, pipes do condenser.The corrosion resistance of aluminum tubes is indeed much worse than that of copper tubes. Many of the refrigerators that have been leaking have been used for 3-6 years and corroded.
Q:How can the refrigerator aluminum pipe leak?
2. Replace and repair evaporator. All need to be dug out from the freezing room, replaced, repaired, restored, and filled with a foaming agent, and then added refrigerant, the price is not expensive.
Q:What are the top ten enterprises in China's aluminium pipe industry?
4 Fenglv aluminum material (A Well-Known Trademark in China China, famous brand, famous brand in Guangdong Province, Guangdong famous brand, Guangdong Feng Aluminum Co. Ltd.)5 Zhong Wang aluminum (China famous brand, China well-known trademark, Liaoning famous brand products, China Zhong Wang Holdings Limited)6 (Chinese Hing Fat aluminum brand, A Well-Known Trademark in China, Chinese aluminum enterprise ten, Xingfa Aluminum Holdings Limited)7 Nanshan aluminum (China famous brand, China well-known trademark, China aluminum enterprise ten, Shandong Nanshan aluminum Limited by Share Ltd)
Q:Does GREE have aluminium tubes?
There should be none. All the air conditioners are copper tubes
Q:What's the difference between a refrigerator and a copper tube?
Price。 The price of copper tube is higher than that of aluminium tube, so the cost of using all copper tube refrigerator will be raised greatly.Weight. Copper has a density greater than aluminum. Aluminum can reduce the weight of the refrigerator.Corrosion resistance. The corrosion resistance of copper is greater than that of aluminum. Aluminum tube in the sealed refrigerator, easy to be corroded by water and lead to refrigerant leakage, and copper corrosion resistance is stronger, unfavorable corrosion.Thermal conductivity. The heat conductivity of the copper tube is better than that of the aluminum tube, so the heat transfer effect of the refrigerator with the copper tube is good.Generally speaking, physical properties of copper is better than aluminum, but considering the cost factors, now basically do not use the refrigerator refrigeration system used in all aluminum tube, to make the refrigerator, only the key parts, such as capillary, compressor outlet for brass.
