What Is Role of Aluminium Pipe Joints in Boat Making
During the operation of ships, the pipeline system undertakes the important task of transporting various fluids such as fuel, fresh water, seawater, compressed air, etc., and the performance and quality of pipeline accessories, as an important part of the pipeline system, directly affect the safety and stable operation of the ship.
Aluminum pipe fitting
Aluminum pipe connections play the role of connecting different pipelines or pipelines with equipment in the ship's pipeline system, and are the key to ensuring the integrity of the pipeline system. Common connection accessories include flanges, elbows, tees, crosses, etc.
Flange: As one of the most commonly used connection methods, aluminum flanges have the advantages of high strength, good sealing performance, and easy disassembly. There are many types of flanges used on ships, such as flat flanges, aluminum slip on flanges, aluminum socket weld flanges, aluminum weld neck flanges,etc.
The key point is to select the appropriate flange type and specification according to the pressure, temperature, medium and other parameters of the pipeline, and at the same time ensure the flatness and roughness of the flange sealing surface to ensure a good sealing effect.
Elbow: It is used to change the direction of the pipeline. Depending on the bending angle, there are many types such as 45°, 90°, and 180°. When a ship arranges pipelines in a narrow space, the rational use of elbows can effectively save space. The key point is that the radius of curvature of the elbow must meet the design requirements. Too small a radius of curvature will increase fluid resistance and affect the normal operation of the pipeline system.
Tee and Cross: used to realize the diversion and confluence of pipelines. Tees and Crosses are often used in the bilge water system and ballast water system of ships. When choosing, pay attention to the matching of the pipe diameter with the connecting pipe, and the internal flow channel should be smooth to reduce the resistance of fluid flow.
Control accessories
Valves: They are the most widely used control accessories in ship pipeline systems, with a wide variety of types, such as gate valves, stop valves, ball valves, butterfly valves, etc. Gate valves are suitable for fully open or fully closed occasions, and have good sealing performance.
Throttle valve: adjusts the flow rate by changing the cross-sectional area of the flow channel. It is often used in situations where precise flow control is required, such as flow regulation of ship fuel systems. The key point is that the adjustment accuracy of the throttle valve must meet the system requirements, and at the same time, attention should be paid to preventing cavitation during the throttling process, which may damage the valve and pipeline.
Check valve: its function is to prevent the backflow of fluid in the pipeline and ensure the safety of the system. Check valves are often installed in the pump outlet pipeline, steam pipeline and other locations of the ship.
Support accessories
Support accessories are used to support and fix pipelines to prevent deformation or vibration of pipelines due to self-weight, medium pressure, thermal expansion and contraction, etc. Common ones include hangers, brackets, pipe clamps, etc.
