There are various types of stainless steel duct fittings, which play a crucial role in ventilation and air conditioning systems. The following are the main types of stainless steel duct fittings and their brief descriptions:
1. Bend
Function: Used to change the direction of the air duct and make the pipeline turn at a certain angle.
Classification: According to the relationship between bending radius and pipe diameter, it can be divided into elbows (bending radius less than or equal to 1.5 times the pipe diameter) and bends (bending radius greater than 1.5 times the pipe diameter).
Application: In ventilation systems, elbows are used to adjust the direction of airflow and ensure smooth airflow.
2. Three way and four way connections
Function: Used to connect multiple air ducts to achieve airflow diversion or merging.
Classification: Three general rules are used for connecting three air ducts, and four general rules are used for connecting four air ducts.
Application: In complex ventilation systems, three-way and four-way fittings are used to construct airflow networks to meet different ventilation needs.
3. Variable diameter pipe (big and small head)
Function: Used to connect two different diameters of air ducts and achieve a transition in diameter.
Classification: Concentric and eccentric reducers, distinguished based on the shape and position of the variable diameter section.
Application: In ventilation systems, variable diameter pipe fittings serve as a bridge when connecting ducts of different diameters.
4. Flanges
Function: Used for connecting the ends of air ducts, enhancing the sealing and stability of the connection.
Features: Flange connections are usually used in conjunction with gaskets and bolts to form detachable connections, making them easy to install and maintain.
Application: Flanges are indispensable accessories in duct systems and are widely used in various duct connection scenarios.
5. Soft connector
Function: Used to reduce vibration and noise caused by fan connections in air ducts, while providing a certain degree of flexibility.
Features: Short length, easy installation, good flexibility.
Application: Soft joints are usually installed between fans and ducts to provide shock absorption and noise reduction.
6. Guide vanes
Function: Installed inside the air duct, used to guide airflow, improve airflow distribution, and enhance ventilation efficiency.
Application: In situations where accurate control of airflow direction is required, such as laboratories, clean rooms, etc., guide vanes play an important role.
7. Muffler
Function: Used to reduce noise inside the air duct and improve the working environment.
Classification: According to the different principles and structures of noise reduction, it can be divided into resistive mufflers and resistant mufflers.
Application: In ventilation systems that require noise control, mufflers are essential accessories.
8. The sky is round and the earth is square
Function: Used to connect circular and rectangular ducts, achieving transitions between ducts of different shapes.
Application: In ventilation systems, when circular fittings are used to connect ducts of different shapes, they can ensure smooth transition of airflow.
9. Other accessories
Air duct plug: used to seal the end of an air duct to prevent air leakage.
Duct hanger: used to support and secure ducts, ensuring their stability and safety.
Duct support bracket: Similar to a hanger, it is also used to support ducts, but is usually installed on the ground or wall.
