Seamless aluminum tube
We produce high-grade seamless aluminum tubing
According to the processing method is divided into extrusion seamless aluminum tube, cold drawn precision seamless aluminum tube, rolling seamless aluminum tube. Among them, the cold drawing precision of seamless aluminum tube with high precision, good surface quality.
The Main Process of Seamless Aluminum Tube
Seamless aluminum tubes are produced by piercing extrusion, while conventional aluminum tubes are usually extruded by a combined die. Aluminum Alloy seamless tube production principle and process production using the short rod, high temperature, slow speed extrusion process, especially to control the “three temperature”, aluminum rod extrusion cylinder, and die to keep clean, aging time and temperature are adjusted according to the thickness and diameter of the wall.
Cold Drawn seamless aluminum Tube (pipe)
In the beginning, a drawn structural tube goes through the same process as an extruded tube. However, where an extruded tube is cooled after it is forced through the die, the drawn tube is sent through a second die. This process is called cold drawing or cold working, and it is here that the final dimensions of the product are determined. A drawn tube is just as suitable for transporting gases or liquids under pressure as a seamless extruded tube.
a seamless extruded tube is brought to final size by drawing through a die. Closer size tolerances and thinner wall thicknesses than that of extruded tube are available.

The Difference Between a Seamless Tube and a Slit Tube
A seamless tube is a tube that does not have any welding seam. A seamless tube may also be known as a seamless pipe.
It differs from the main slit tube in that
Aluminum ingot processing method
Indirect extrusion (seamless tube) surface turning, no scale involved.
Direct extrusion (slit tube) of the skin without turning, the product may be involved in the oxide layer.
Status of aluminum ingot and container
Seamless pipe flow, frictionless;Uniform flow of metal;
There is relative friction in the slit pipe. Uneven metal flow; The product contains coarse crystals.
Product appearance
The inner and outer walls of seamless tube are smooth and clean.No burning or cracking on the surface;
The appearance of slit tube is generally smooth.
Mechanical properties
Seamless tube product head and tail metal flow uniformity; High dimensional accuracy; Good fatigue resistance; Consistent mechanical properties;No lamellar tissue.
Metal flow from end to end of products with slit pipes is not uniform; Mechanical properties inconsistent; Lamellar tissue is easy to appear.
Compare with slit tube the advantage as follow
Seamless tube is especially suitable for extrusion of alloy bars and tubes with super hardness (such as alloy 2014, alloy 2024, alloy 2A21,alloy 2017, alloy 5052, alloy 5083,alloy5757, alloy7075, alloy 7005 etc).
Slit tubes are suitable for extrusion of general hardness of alloy products of general added value.(such as alloy6063, alloy 6061, alloy 6082 series,alloy 3003,alloy 1070)
Economy
Seamless tube relatively high price, suitable for manufacturing high-precision products.
Slit tubes are relatively inexpensive and suitable for general purpose products.

Aluminum tube is a kind of non-ferrous metal tube, which refers to a metal tubular material that is made of pure aluminum or aluminum alloy by extrusion processing to be hollow along its full length in the longitudinal direction.
It is widely used in industries such as automobiles, ships, aerospace, aviation, electrical appliances, agriculture, electromechanical and household appliances.
Classification of aluminum tube/pipe
Aluminum tubes are mainly divided into the following types:
Divided by shape: square tube, round tube, pattern tube, special-shaped tube, global aluminum tube.
According to the extrusion method: seamless aluminum tube and ordinary extruded tube
According to the precision: ordinary aluminum tubes and precision aluminum tubes, of which precision aluminum tubes generally need to be reprocessed after extrusion, such as cold drawing, fine drawing, and rolling.
According to thickness: ordinary aluminum tube and thin-walled aluminum tube
Performance: corrosion resistance, light weight.
Aluminum tube advantages: First, welding technology advantages: the welding technology of thin-walled copper-aluminum tubes suitable for industrialized production is known as a world-class problem and is a key technology for replacing copper with aluminum for connecting pipes for air conditioners.
The second is the service life advantage: from the perspective of the inner wall of the aluminum tube, since the refrigerant does not contain moisture, the inner wall of the copper-aluminum connecting tube will not corrode.
The third is the energy-saving advantage: the lower the heat transfer efficiency of the connecting pipe between the indoor unit and the outdoor unit of the air conditioner, the more energy-saving, or in other words, the better the heat insulation effect, the more energy-saving.
Fourth, excellent bending performance, easy to install and move
Surface treatment
