Aluminum pipes are mainly divided into the following types

Aluminum pipes are mainly divided into the following types
Divided by appearance: square pipe, round pipe, pattern pipe, special shape pipe, global aluminum pipe.
According to the extrusion method: seamless aluminum tube and ordinary extrusion tube
Divided by accuracy: ordinary aluminum tube and precision aluminum tube, the precision aluminum tube generally needs to be reprocessed after extrusion, such as cold drawing, rolling.
Divided by thickness: ordinary aluminum tube and thin wall aluminum tube
Performance: Corrosion resistance, light weight.
characteristic
It is a kind of high strength duralumin, which can be strengthened by heat treatment. It has medium plasticity in annealing, hardening and hot state, and good weldability in spot welding. When using gas welding and argon arc welding, aluminum tube has the tendency to form intergranular cracks; The machinability of aluminum tube is good after quenching and cold hardening, but bad when annealed. Corrosion resistance is not high, often using anodic oxidation treatment and paint method or surface coated with aluminum layer to improve the corrosion resistance. It can also be used as a mold material.
Advantages of aluminum tube: one is welding technology advantages: suitable for industrial production of thin-wall copper aluminum tube welding technology, known as a world-class problem, is the key technology of air conditioner connecting pipe aluminum instead of copper.
Second, the service life advantage: from the inner wall of the aluminum tube, because the refrigerant does not contain moisture, the inner wall of the copper aluminum connection tube will not corrode.
Three is energy-saving advantage: air conditioner indoor unit and outdoor unit connection pipeline, the lower the heat transfer efficiency, the more energy saving, or, the better the heat insulation effect, the more power saving.
Four is excellent bending performance, easy to install, move

Aluminum plate demand status

Supply aluminum plate material five areas of excess production - supply aluminum plate material ceramic aluminum plate punching aluminum plate aluminum ceiling mesh strong aluminum plate carved aluminum plate shaped tile ferulosi plate aluminum plate materials and other products in five areas of excess capacity analysis "from 100 million tons, to now 800 million tons, still say overcapacity", China Iron and Steel Association deputy secretary general in bear "China Investment" interview said. In contrast, China Steel Association released that China's steel production capacity had reached 800 million tons at that time, but the actual steel production capacity was only 400 million tons, and there were still 400 million tons of capacity that had not been approved by the state.

Aluminum plate maintenance and maintenance

Special attention should be paid to the selection of appropriate detergent, a basic principle is: must choose neutral detergent! Do not use strong alkaline detergents such as potassium hydroxide, sodium hydroxide or sodium carbonate, strong acid detergents, abrasive detergents and paint-soluble detergents.

Aluminum rod product classification

According to the different metal elements contained in aluminum rods, aluminum rods can be roughly divided into 8 categories, that is, can be divided into 9 series:

Aluminum tube

Divided by appearance: square pipe, round pipe, pattern pipe, special shape pipe, global aluminum pipe.

Aluminium coil

On behalf of 1000 series aluminum plate is also known as pure aluminum plate, in all series 1000 series belong to a series containing the most aluminum. Purity can reach more than 99.00%. Because it does not contain other technical elements, the production process is relatively simple and the price is relatively cheap.
