Description

Technical Field

[0001] The utility model relates to the technical field of flanges, in particular to an extruded aluminum alloy flange. Background Art

[0002] Flange, also called flange flange or flange. Flanges are used in pairs as parts that connect pipes to each other and are used for connecting pipe ends. Flanges are also used on equipment inlets and outlets for connecting two devices. When using flanges to connect pipes, the interface between the pipe and the flange needs to be welded so that the flange can be firmly fixed to one end of the pipe. However, most of the existing flanges are exposed to the outside and may be damaged due to the influence of the external environment. For example, a Chinese patent discloses "an extruded aluminum alloy flange" with an application number of "202023283872.3". It uses a limit interface to insert into the inside of the pipe to limit the flange to prevent the flange from shaking during welding, and then uses a fixing ring and a restraining belt to restrain the pipe, so that the flange is firmly connected to one end of the pipe, so that the flange is not easy to slip out of position during welding, so that the welding effect is better, and the user does not need to touch the flange or adjust the position of the flange during welding, and can accurately weld the flange, effectively preventing the user from being scalded during welding, and providing convenience for the user, but the flange is still exposed to the outside and is easily damaged by the external environment (wind and rain).
