Hot rolling, cold drawing, hot expansion
According to different production methods, it can be divided into hot rolled tubes, cold rolled tubes, cold drawn tubes, extruded tubes and so on.
1.1 Hot-rolled 5083 seamless tubes are generally produced on automatic tube rolling units. The solid pipe blank is inspected and removed for surface defects, cut to the required length, centered on the end face of the perforated end of the pipe blank, and then sent to a heating furnace to be heated and perforated on a perforator. While the perforation is continuously rotating and advancing, under the action of the roller and the head, a cavity is gradually formed inside the tube blank, which is called a capillary tube. Then it is sent to the automatic pipe rolling mill to continue rolling. Finally, the whole wall thickness is adjusted by the sizing machine and sizing by the sizing machine to meet the specifications. It is a more advanced method to produce hot-rolled 5083 seamless tubes using a continuous tube rolling mill.


1.2. To obtain 5083 seamless pipe with smaller size and better quality, cold rolling, cold drawing or a combination of the two must be used. Cold rolling is usually carried out on a two-roll mill, and the steel tube is rolled in a ring-shaped groove composed of a variable-section circular hole groove and a fixed conical head. Cold drawing is usually performed on a single-chain or double-chain cold-drawing machine of 0.5 to 100T.
1.3. Extrusion method: The heated pipe blank is placed in a closed extrusion cylinder, and the perforated rod and the extrusion rod move together to extrude the extrusion from a smaller die hole. This method can produce smaller diameter steel pipes.
5083 Seamless aluminum tube: outer diameter [∮120--∮600mm] * wall thickness [20mm-100mm] * length [1000mm-4000mm]
5083 Aluminum square tube: outer diameter [∮10--∮203.2mm] * wall thickness [1mm-12mm] * length [6000mm]
