1. Threaded connection
Threaded connection is a kind of connection method that achieves sealing by threads occlusing to each other, and is often used to connect small-diameter aluminum alloy pipes. The connection is easy to install, does not require professional tools, and is easy to disassemble and maintain. However, the threaded connection strength is relatively low, which is suitable for the conveying of low-pressure media.
2. Flange connection
Flange connection is a way to achieve pipe connection through flange and bolt splicing with each other. Flange connections are a very common choice where high pressure and tightness requirements are required. The flange connection method of aluminum alloy pipe includes butt welding flange and flange kit connection. The butt welding flange needs to press the aluminum alloy pipe at both ends into a flat surface first, and then form a seal after the butt welding flange at both ends, and the flange kit connection is to splice the aluminum alloy pipe through the relevant accessories of the flange kit.
3. Hanging connection
Suspended connection is a way to hang aluminum alloy pipes on a bracket by attaching clamps. This connection method is suitable for large-diameter aluminum alloy pipes, and has high strength and corrosion resistance.
4. Welding connection
Welding is a method of joining aluminum alloy pipes together by arc welding, argon arc welding, or laser welding. This connection method is suitable for high temperature, high pressure, high corrosion media transportation and pipeline connection requires high strength occasions. However, because the heat conductivity of aluminum alloy is good, it is necessary to pay attention to the relevant technology and operation during welding.
There are many connection methods for aluminum alloy pipes, among which which which the choice of connection method should be determined according to the specific situation, including the use conditions of the pipeline, the physical and chemical properties of the medium, the installation location and so on.
