The aluminum alloy pipe elbow is usually used to connect with the pipeline and is mainly used to change the direction of the pipeline. Therefore, it is necessary to understand how to connect and use under various conditions when carrying out pipeline construction.

Aluminum alloy pipe is applicable to the connection of metal pipe with diameter ≤ 42mm and metal pipe fittings or non-metal pipe fittings and valves. A gasket is added in the middle, which is convenient for construction and disassembly. It is generally used in instruments and control systems.

Aluminum alloy pipe bending is the most commonly used bending method. According to the different bending equipment, it can be divided into manual bending and pipe bending machine bending. Manual bending is mainly used in small batch production because it does not require special bending equipment, the bending device is simple, the manufacturing cost is low, and the adjustment is convenient, but the labor intensity is high and the productivity is low. According to whether the pipe bender has a mandrel or not, it can be divided into cored pipe bender and coreless pipe bender.

There are many methods for bending pipe. According to the bending forming method, it can be divided into roll bending, press bending, push bending and round bending; According to whether the mold is used during bending, it can be divided into mold bending and non mold bending; The bending can be divided into cored bending and coreless bending according to whether there is a core rod during bending; According to whether the bending is heated or not, it can be divided into cold bending and hot bending. In recent years, new bending processes such as zero radius bending, medium frequency induction bending, thermal stress bending and laser forming bending have also appeared.
