Aluminum pipe refers to a kind of hollow non-ferrous metal pipe produced by extrusion of pure aluminum or aluminum alloy, which can have one or more closed through holes and uniform wall thickness. It is widely used in ships, agriculture, electromechanical, pretending, aerospace, automobile and other industries, and is widely used in our lives.
According to different aspects, the types of aluminum pipes are also different. According to the appearance, there are square tubes, round tubes, special-shaped tubes, patterned tubes and global aluminum tubes. According to the extrusion method, there are ordinary extruded tubes and seamless aluminum tubes. According to the accuracy, there are ordinary aluminum tubes and precision aluminum tubes. According to the thickness, there are ordinary aluminum tubes and thin-walled aluminum tubes.
Generally, aluminum tubes are made of high-strength hard aluminum, which is strengthened by heat treatment. The plasticity is moderate in annealing, just quenching and hot state, and the weldability of spot welding is excellent. During gas welding and argon arc welding, aluminum tubes may form cracks. After quenching and cold work hardening, the machinability of aluminum tubes is moderate, but it is not good in annealing state. Because of its poor corrosion resistance, anodizing, painting or surface coating are often used to improve the corrosion resistance of aluminum pipes.
What are the difficulties in cutting seamless aluminum pipes?
Characteristics and uses of white jade seamless aluminum pipe
Aluminum pipe deviation: in the production process, the actual size is difficult to meet the requirements of nominal size, and the deviation of aluminum-resistant pipes is often greater than or less than the nominal size. The sum of the absolute values of positive and negative deviation values specified in the standard is called tolerance, and the deviation of high-resistance aluminum pipes is called "tolerance zone". Deviation is directional and is expressed as "positive" or "negative". Because the tolerance has no directionality, it is wrong to call the deviation value "positive tolerance" or "negative tolerance".
For seamless aluminum pipes, ensure the integrity of structural parts maintenance engineering design. Stainless steel aluminum pipe has both mechanical strength and high extensibility, and other parts are easy to process and manufacture, which can meet the specific needs of architects and structural designers. Stainless steel aluminum pipes are widely used in petroleum, chemical industry, nuclear power plant, food manufacturing, construction, shipbuilding, paper making and other industries, and different industries have different uses, which shows the use value of various industries. As a company casting stainless steel and aluminum pipes, our long-term products are reliable in quality and excellent in performance. Next, briefly introduce the advantages of casting stainless steel aluminum pipes to friends from small chapters. First of all, the shape and size of the cast stainless steel aluminum pipe are accurate, and the machining amount is small. The advantage of castings is that they can be made into more complex shapes. The cost is relatively low. Compared with ordinary sand casting, the centrifugal stainless steel aluminum pipe is much finer in structure and much better in quality, and it is not easy to have problems such as loose structure, porosity and trachoma. 6063 aluminum pipe is easy to process and connect.
Difficulties in plasma cutting dust removal of seamless aluminum tubes;
1. When the plasma nozzle of seamless aluminum tube is cut, it is blown in two directions together with air, and smoke is ejected from both ends of the aluminum tube, so it is difficult for the aluminum tube to recover smoke from the air inlet in one direction of the steel tube.
2. The cold air around the air inlet of the aluminum tube enters the air inlet from outside the mechanical clearing, and the air volume is large. The total amount of smoke and cold air in the aluminum tube is greater than the useful air volume inhaled by the vacuum cleaner. After that, it is impossible to cut off the aluminum pipe and completely absorb the smoke.
3. Because the interval between the cutting parts is far away from the dust suction port, it is difficult for the wind force of the aluminum pipe to reach the suction port to attract dust.
Plate materials require clean surface, so it is necessary to adopt high-quality die steel, strict die heat treatment technology and mechanical processing, and implement CNC process regulations to obtain high-quality dies with high strength, high toughness, high precision and low surface roughness. The state of aluminum alloy is different, and there are not only varieties of aluminum alloy, but also the state difference of aluminum alloy is small, and the hardness and processability are different in different States, so the state difference of aluminum alloy is also an important index of products. F status: free machining status. It is suitable for products with special requirements for work hardening and heat treatment conditions in molding, and the mechanical properties of products in this state are not specified.
