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 pipeline system (energy-saving pipeline, super pipeline, and fluid wire rod) has been widely used in European and American enterprises to transport compressed air, vacuum, nitrogen and inert gas. As a clean and efficient energy, compressed air is second only to electric power in factories and enterprises, so it is very important. The compressed air transmission pipelines supporting domestic air compressors were originally carbon steel pipes, galvanized pipes and PVC pipes.

At present, the aluminum alloy compressed air pipe has been widely used in the compressed air system. Compared with the traditional seamless steel pipe, it has obvious advantages because it is clean, light, fast to install, reusable and not easy to rust.
