In daily life, seamless aluminum pipe is mainly used in air conditioning, oil pipe, high pressure water pipe and other facilities which have strict requirements on pipe density and strength. Therefore, the production of seamless aluminum pipe has high requirements for processing equipment. Only seamless aluminum pipe suppliers equipped with reverse double acting extruder can produce seamless aluminum pipe. At present, there are many shapes of seamless aluminum pipe in the market, such as round tube, square tube, flat tube, elliptical tube, hexagonal tube and so on.

The chemical composition of seamless aluminum pipe has become an important part of producing high quality aluminum alloy building profiles. It has medium strength heat treatment strengthening alloy. Magnesium and silicon are the main alloying elements. The main work of optimizing chemical composition is to determine the percentage of magnesium and silicon. It is widely used in the framework of aluminum doors and windows and curtain walls. In order to ensure that doors, windows and curtain walls have high wind pressure resistance, assembly performance, corrosion resistance and decoration, the comprehensive performance requirements of aluminum alloy profiles are far higher than seamless aluminum pipe suppliers industry profile standards.

In the national standard GB / t3190, different chemical composition values will lead to different material properties, which makes seamless aluminum pipe in all walks of life have a good development space, also made a great contribution.

Seamless aluminum tube is a kind of piercing extrusion method. Seamless aluminum tube has the characteristics of small specific gravity, easy processing, high mechanical strength, and its manufacturing process is relatively strict and fine.

However, some problems should be paid attention to in order to produce high quality seamless aluminum tube.

Large seamless aluminum pipe is usually formed by hot extrusion, and then through subsequent practical treatment. Small seamless aluminum pipe can be hot extrusion or cold drawing, and then after the actual treatment.

Aluminum hydroxide produced in the production process of seamless aluminum tube needs continuous extrusion, which makes many seamless aluminum pipe suppliers dehydrate seriously and form sand holes in the extrusion process. In order to prevent sand holes on the seamless aluminum pipe, the round aluminum rod for extrusion shall not have rolling cracks; it shall not be stored in humid environment; the sodium hydroxide content in the cleaning solution shall be about 30%, and the aluminum ion content in the cleaning solution shall be strictly controlled.

Silane rare earth composite films for seamless aluminum tubes were prepared by impregnation method. A layer of Bis silane film was assembled on the surface of the sample, and then cerium conversion film was deposited on the film. The corrosion resistance of silane rare earth composite film on the surface of seamless aluminum tube was studied by electrochemical, droplet and salt spray tests.

Therefore, if you want to choose the right seamless aluminum pipe, you need to have reliable seamless aluminum pipe suppliers as the guarantee, only in this way can we make the product satisfactory. If you want to have a cooperation with good company, I do hope we can suit for your standards.
