3003 seamless aluminum pipe 1, aluminum used in aerospace is used to manufacture aircraft skin, fuselage frame, girder, rotor, propeller, fuel tank, wall plate and landing gear strut, as well as rocket forging ring and spacecraft wall plate.

2. Aluminum materials for transportation are used in car body structural parts, doors and windows, shelves, automobile engine parts, air conditioners, radiators, car body panels, wheels and ships of automobiles, subway vehicles, railway buses and high-speed buses. 3. Aluminum cans for packaging mainly use sheets and foils as metal packaging materials to make cans, lids, bottles, barrels and packaging foils.

Widely used in the packaging of beverages, foods, cosmetics, medicines, cigarettes, industrial products, etc. 4. Printing aluminum is mainly used to make PS plates. Aluminum-based PS plate is a new material in printing industry, which is used for automatic plate making and printing.

5. Aluminum alloy for architectural decoration is widely used in building frames, doors and windows, suspended ceilings, decorative surfaces, etc. Because of its good corrosion resistance, sufficient strength, excellent process performance and welding performance. Such as all kinds of doors and windows, curtain wall aluminum profiles, aluminum curtain wall panels, pressed panels, diamond panels, color-coated panels and so on.

6. Aluminum materials for electronic household appliances are mainly used in buses, overhead lines, conductors, electrical components, refrigerators, air conditioners, cables and other fields. Specification: round bar, square bar, sheet, strip and coil.

2. How is the aluminum tube processed?

There are three main steps in the processing of aluminum pipes. The first step is to melt the aluminum material, and then make it into a certain round bar shape through some process equipment.

These include selecting raw materials according to some specific parameters of aluminum tubes (through calculation and matching), melting raw materials in a furnace to remove excess impurities and gases, and making materials into round bars through some systems. The second step is to help the aluminum tube shape. The main method is through an extruder. In the extrusion process, some auxiliary means will be used to complete and strengthen the heat treatment process of materials.

Finally, it is processed into the shape of aluminum tube through a series of technological means. Finally, some external treatments are carried out on the aluminum pipe, including cleaning the surface of the aluminum pipe and checking whether the surface is smooth. If it is not smooth, you can do some operations such as rubbing. The purpose of this is to obtain a very dense and complete protective film.

After you get the protective film, you need to seal it. The specific operation is to get some metal salts in the membrane holes by adsorption and precipitation, so that the aluminum tube will have its own color. In the third step, the surface treatment of aluminum pipe can also adopt the common sand blasting method.

A simpler way to process aluminum tubes is to operate them directly with a lathe, if the accuracy is not high.

3. How are iron pipes, steel pipes and aluminum pipes shaped?

Let's talk about steel pipes first: the production technology of steel pipe welded pipe and seamless pipe welded pipe is about unwinding, leveling, winding forming (both straight seam welding and spiral welding), welding, removing weld high points, nondestructive testing and flying saw fixed length cutting.

Note that welded pipes are basically produced continuously. The seamless pipe firstly heats the billet and then releases it from the female die, and the male die rotates quickly to squeeze it in, so the produced steel pipe is not good in size.

In order to obtain a large number of precision seamless steel pipes, it is necessary to heat treat, pickle, saponify, cold draw and cold roll the hot rolled steel pipes. The surface roughness of a good cold-rolled pipe is only 0.8. Cast iron pipes are of course cast, and centrifugal casting is more advanced at present.

Stainless steel pipes and titanium pipes are welded and cast, and there is a composite pipe (for example, two materials are welded together by explosive welding), which looks welded.
