Duct flanges play a crucial role in duct systems, and their main functions can be summarized as follows:
1. Connection and fixation
Connecting air ducts: The air duct flange is a key component for connecting air ducts. Two sections of air ducts are firmly connected together through fasteners such as bolts and nuts, ensuring the continuity and stability of the air duct system.
Fixed function: The flange not only connects the air duct, but also fixes the air duct on the bracket or hanger to prevent displacement or shaking of the air duct during operation.
2. Sealing performance
Prevent leakage: Sealing gaskets or sealants are usually provided between the flanges of the air duct to ensure the sealing of the air duct system. This helps prevent air, gas, or dust from leaking from the flange connection and improves the operational efficiency of the system.
Pressure resistance performance: The sealing performance of flanges is also reflected in their ability to withstand a certain pressure difference, ensuring that the duct system can still operate normally in high-pressure or negative pressure environments.
3. Enhance strength and stability
Improve strength: Duct flanges are usually made of metal materials (such as angle steel, flat steel, etc.), which have high strength and rigidity. This helps to enhance the overall strength of the duct system, enabling it to withstand greater wind pressure and vibration.
Stable structure: The flange connection method forms a stable overall structure for the air duct system, which helps reduce deformation and damage caused by factors such as wind pressure and vibration.
4. Easy to install and maintain
Easy installation: The design of the duct flange makes the installation process of the duct more convenient and efficient. The connection and fixation of air ducts can be easily achieved through fasteners such as bolts and nuts.
Easy maintenance: When the air duct system needs to be inspected or maintained, the flange connection method makes it easier to disassemble and replace the air duct. This helps to reduce maintenance costs and improve maintenance efficiency.
5. Adaptability and flexibility
Adapt to different needs: There are various types and specifications of duct flanges to choose from to meet the needs of different duct systems. For example, angle steel flanges are suitable for high pressure, high temperature, or high vibration environments; Common plate flanges are suitable for large-scale standardized production.
Flexible adjustment: In the design and installation process of the duct system, the position and quantity of flanges can be flexibly adjusted according to actual needs to meet different layout and connection requirements.
