Aluminum and aluminum alloy pipes can be produced using various methods such as hot extrusion, cold extrusion, cold rolling, cold drawing (including coiled tube stretching), cold bending, welding (cold bending + high-frequency welding), spinning, continuous extrusion, and more. Currently, there are thousands of varieties of aluminum alloy pipes.
They can be categorized into thin-walled pipes and thick-walled pipes based on their wall thickness. Thick-walled pipes are primarily produced through hot extrusion, with wall thickness typically ranging from 5-35mm, and larger extrusion machines can produce wall thicknesses exceeding 65mm. Thin-walled pipes can be manufactured using methods such as hot extrusion, cold extrusion, cold rolling, cold drawing, and other cold deformation methods, with wall thickness typically ranging from 0.5-5mm. With continuous improvements in cold rolling pipe machines, spinning, and welding methods, the wall thickness of aluminum alloy pipes can be as low as 0.1mm.
They can also be categorized into large-diameter thick-walled pipes, large-diameter thin-walled pipes, small-diameter thin-walled pipes, and more based on their specifications. In terms of cross-sectional shapes, they can be round pipes, elliptical pipes, drop-shaped pipes, semi-circular pipes, square pipes, rectangular pipes, hexagonal pipes, octagonal pipes, pentagonal pipes, trapezoidal pipes, ribbed pipes, and other irregular-shaped pipes. Depending on the variation in cross-section along the length, they can be classified as cross-section pipes or variable-section pipes.
Based on the production methods, they can be categorized as hot extrusion pipes, cold extrusion pipes, Conform extrusion pipes, hot-rolled pipes, cold-rolled pipes, cold-drawn pipes, spun pipes, cold-bent pipes, welded pipes, spiral pipes, coiled tube stretch pipes, bimetallic pipes, adhesive pipes, and more.
In terms of uses, they can be classified as military and civilian conduits, shell pipes, container pipes, drilling pipes, casing pipes, waveguide pipes, heat dissipation pipes, automotive exhaust pipes, condenser pipes, evaporator pipes, nozzle pipes, agricultural irrigation pipes, flagpoles, wire poles, pantographs, and various other structural and decorative pipes, as well as pipes for household items, among others.
