How Do Aluminum Tube and Flange Match Each Other
Aluminum and its alloys have been widely used in modern shipbuilding due to their many excellent properties such as light weight, high strength and corrosion resistance. Among them, the combination of aluminum flanges and aluminum pipes constitutes an indispensable part of the ship's piping system. They each play a unique role and ensure the stable operation of various systems on the ship through exquisite cooperation.
Aluminum Flange
As an important part for connecting pipes and pipes, pipes and equipment, aluminum pipe flanges bear the dual tasks of connection and sealing in the ship's piping system. Structurally, it is usually disc-shaped with several bolt holes, and is fastened to another flange through bolts to achieve pipe docking. Aluminum flanges are widely distributed in many systems of ships, such as fuel systems, seawater cooling systems, compressed air systems, etc.
Aluminum flanges have excellent corrosion resistance. On some ocean-going ships, the pipeline system using aluminum flanges can still maintain good performance after years of seawater immersion and harsh marine environment, without obvious corrosion damage.
Aluminum pipe
Aluminum tubes are mainly used for the transportation of various fluids in ships, and are the "blood vessels" for the normal operation of many systems of ships. Common marine aluminum tubes are mostly made of aluminum-magnesium alloy, which combines the advantages of aluminum and magnesium.
On the one hand, the lightweight characteristics of aluminum are retained, and its density is relatively low, so that after a large number of aluminum tubes are installed on the ship, the overall weight will not increase excessively, which helps to improve the ship's sailing speed and handling performance. On the other hand, the addition of magnesium gives the aluminum tube higher strength and good corrosion resistance, which can resist long-term erosion by seawater and ensure the stable operation of the pipeline in a complex marine environment.
Aluminum flange and aluminum tube matching
There are many ways to match aluminum flange and aluminum tubing for sale, the most common ones are welding connection and threaded connection. Welding connection is a relatively strong connection method and is widely used in shipbuilding. Through welding processes such as argon arc welding, the aluminum tube and aluminum flange can be tightly integrated to form a high-strength connection joint.
Threaded connection is easy to install and disassemble, and is suitable for some parts that require frequent maintenance or overhaul. When threaded connection is used, the end of the aluminum tube is processed with an external thread, and the middle of the aluminum flange is provided with an internal thread, and the two are connected by screwing. In order to ensure the sealing of the connection, sealing tape or sealant is usually wrapped around the thread.
In order to ensure the reliability of the aluminum flange and the aluminum tube, sealing is very important. Sealing gaskets, such as rubber gaskets, polytetrafluoroethylene gaskets, etc., are usually used at the connection parts. These gaskets have good elasticity and corrosion resistance, and can fill the tiny gap between the Aluminum pipe fitting and the aluminum tube to prevent fluid leakage.
