Aluminum alloy pipes come in a wide variety of types and are used across many industries. They can be manufactured through several methods, including hot extrusion, cold extrusion, cold rolling, cold drawing (such as coil stretching), cold bending, welding (using cold forming combined with high-frequency welding), spinning, and continuous extrusion. Today, the range of aluminum alloy pipe varieties has grown to thousands of different options. Based on wall thickness, they can be classified into thin-walled and thick-walled pipes. Thick-walled pipes are typically produced using hot extrusion, with wall thicknesses ranging from 5 to 35 mm. Large extruders can even produce thick-walled pipes with walls exceeding 65 mm. Thin-walled pipes, on the other hand, are made using cold deformation techniques such as hot extrusion, cold extrusion, cold rolling, and cold drawing. Their typical wall thickness ranges from 0.5 to 5 mm. With advancements in cold-rolled pipe mills, as well as the development of spinning and welded pipe technologies, the minimum wall thickness of aluminum alloy pipes has been reduced to less than 0.1 mm in some cases. In terms of size, they can be categorized into large-diameter thick-walled pipes, large-diameter thin-walled pipes, and small-diameter thin-walled pipes. Based on cross-sectional shape, they include circular tubes, elliptical tubes, drop-shaped tubes, oblate tubes, Square Tubes, Rectangular Tubes, hexagonal tubes, octagonal tubes, pentagonal tubes, trapezoidal tubes, ribbed tubes, and various other shaped tubes (as shown in Figure 3-2-4). Additionally, they can be divided into constant-section tubes and variable-section tubes depending on whether the cross-section changes along the length of the pipe. From a production standpoint, aluminum alloy pipes can be further categorized into hot-extruded tubes, cold-extruded tubes, Kangfum-extruded tubes, hot-rolled tubes, cold-rolled tubes, spun tubes, cold-bent tubes, welded tubes, spiral tubes, coil-stretched tubes, bimetallic tubes, and bonded tubes, among others. Finally, based on their application, these pipes serve a wide range of purposes, including military and civilian conduits, casing tubes, container tubes, drilling tubes, casings, waveguides, heat pipes, condenser tubes, evaporator tubes, nozzle tubes, agricultural irrigation systems, flagpoles, utility poles, and current collection bows. They are also widely used in decorative applications, household items, and structural components. aluminium pergola Tianjin Alcoa International Trade Co., Ltd. , https://www.tjalcoa.com
