Description
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.
