Varieties and uses of aluminum alloy pipes:
Aluminum and aluminum alloy pipes can be hot extruded, cold extruded, cold rolling, cold drawing (including coil drawing), cold bending, and cold bending.
Welding (cold bending + high frequency welding), spinning, continuous extrusion and other methods of production. At present, the varieties of aluminum alloy pipes have reached more than several thousand.
The wall thickness of the pipe can be divided into thin wall tube and thick wall tube. The thick wall tube is mainly produced by hot extrusion. The thickness of the wall is generally 5~35 mm, and the maximum wall thickness of the large extruder can be over 65 mm. By hot extrusion, cold extrusion, cold rolling, cold drawing and other cold deformation method for manufacturing thin tube wall thickness is generally 0.5 ~ 5 mm, with the continuous improvement of cold rolling mill, spinning method and welding method appears, the minimum wall thickness of Aluminum Alloy can be as small as 0.1 mm.
According to the specification, it can be divided into large diameter thick wall tube, large diameter thin wall tube and small diameter thin wall tube. According to the section shape can be divided into circular tube, oval tube, drop shaped tube, oblate tube, square tube, rectangular tube, pipe, tube, octagonal six angle five angle trapezoidal pipe, tube, ribbed tube and other special-shaped tube (Figure 3-2-4). The change of the section along the length can be divided into a constant section tube and a variable section pipe.
