Aluminum tube is a popular tube on the market. It is lightweight, durable and easy to build. It is also more suitable for use in home decoration. The main disadvantage of aluminum pipe is that when used as a hot water pipe, long-term thermal expansion and cold shrinkage will cause the wall of the aluminum tube profiles to be displaced and cause leakage. The inner and outer layers of the aluminum tube are made of special polyethylene materials, which are clean, non-toxic and smooth. It can be used for more than 50 years. Polyethylene is a non-toxic and odorless plastic with good impact resistance, corrosion resistance and weather resistance. The middle layer is longitudinally welded with aluminum alloy, so that the aluminum tube profiles has the compressive strength of metal, and the impact resistance makes the tube easy to bend and does not rebound. Aluminum tubing has the characteristics of strong pressure resistance of metal tube and is a model of new generation of tube. This article will show you the basic information of the aluminum tube profiles.

Detailed introduction of the aluminum tubing

The aluminum tube profiles is divided into five layers from the inside to the outside, which are PE plastic inner layer, inner adhesive layer, aluminum tubing layer, outer adhesive layer and PE plastic outer layer. Aluminum pipe is a kind of high-strength hard aluminum, which can be strengthened by heat treatment. Annealing, quenching, and thermal plasticity are medium, with good spot welding performance. Aluminum is a pipe made of pure aluminum alloy or aluminum alloy. The quality of the aluminum tube is related to the thickness of the aluminum layer, the welding process and whether there is false welding.


The use of the aluminum pipes

Aluminum tube profile is one of the most widely used non-ferrous metal structural materials in industry. It has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. With the rapid development of industrial economy, the demand for aluminum tube profiles is increasing.

There are many kinds of aluminum tube. According to their strength characteristics and processing properties, aluminum pipe profiles are generally divided into three categories: pure aluminum, soft alloy and hard alloy. The surface quality of aluminum tube profile is required to be high, but its hardness is not high, especially in hot state. Therefore, in the process of production and shipment, great attention should be paid to avoid bumping hard objects to prevent bumping. This requires strengthening the protection of products in production and lifting, and at the same time, we must handle with care, protect the surface and produce in a civilized way. Aluminum tube profiles are easy to adhere to aluminum during extrusion, which often adhere to the tools locally, resulting in various defects on the inner and outer surface of the pipe. Therefore, in addition to using process lubrication, the surface finish and surface hardness of the tools are required to be high, and all the surfaces in contact with the pipe should meet the process requirements. Many aluminum tube profiles are easy to weld together under high temperature and pressure, which brings favorable conditions for the production of pipe materials.


How to choose the right aluminum tube profiles?

The hardness, strength, corrosion resistance, processability and weldability should be considered when selecting aluminum tube profiles. The material of aluminum pipe profile is relatively soft, so it is easy to deform in stamping production. In addition to the requirements on the die, the following points should be done in stamping production:

1.In order to punch the aluminum tube profile well and reduce the defect rate, 5S, especially cleaning, must be done well, including the mold, punch table, assembly line and packaging materials must be free of sharp debris, no dirt, clear and regular rectification, mold must be cleaned up and down, no debris.

2. Aluminum pipe profiles are easy to heat up and become hard together. Therefore, it is necessary to apply some pressing oil on the material during punching and blanking (which can dissipate heat and smooth dredge blanking) before stamping.


I believe you will understand the knowledge of aluminum tube profiles better after reading this article.
