Seamless aluminium tube are a major variety of extruded products. At present, the pipe extrusion method is mainly used for the production of copper and copper alloys, aluminum and aluminum alloy seamless pipes. When the
seamless aluminium tube is produced by the extrusion method, the following advantages are obtained compared with the production of the
seamless aluminium tube by the hot rolling method: the quality of the extruded tube is higher than that of the hot rolling; the extrusion method can produce a plurality of varieties and a plurality of specifications of the tube. The extrusion can obtain a large deformation amount at one time; the extrusion can produce a wool having a thin wall thickness, and therefore, the cold working pass can be reduced.
The production methods of
seamless aluminium pipe mainly include extrusion, drawing, rolling, spinning, welding and the like. The aluminum pipe produced by the welding method belongs to a slotted aluminum pipe. Pipes produced by split casting and tongue die extrusion using solid ingots also belong to seamed pipes. Pipes produced by other methods are
seamless aluminium pipe.
