Top quality
Galvanized steel sheet: Most popular, has good durability and corrosion resistance, reasonable price.
Stainless steel (stainless steel): Including stainless steel 201, 304, 316. Used for special environments requiring high hygiene, absolute corrosion resistance (such as food, pharmaceutical, medical factories, clean rooms) or harsh environments.
Aluminum: Less common in industrial duct applications, often used for small ducts.
Ventilation and air conditioning system (HVAC): Connecting circular duct sections in office buildings, commercial centers, apartments, and factories.
Dust and smoke extraction system: Connect pipes to collect dust and smoke from machinery or production areas.
Civil and light industrial ventilation systems: Where there are requirements for construction speed and cost.
Shape: A round, short, hollow piece of metal pipe.
Size:
Manufactured according to the diameter of the circular duct it will connect to (e.g. D100mm, D200mm, D300mm, etc.).
The length of the connector is usually short enough to create a strong grip for the joint.
Material thickness: Depending on the pipe diameter and pressure in the system, it is usually equivalent to or a little thicker than the air pipe to ensure joint stiffness.
Quick and easy installation: The pipe connection process is simple, does not require many complicated tools.
Reasonable cost: The cost of connectors is often lower than using a flange system.
Good tightness: When properly sealed, the joint has high tightness, minimizing air loss.
Aesthetics: The joints are quite neat, less visible to the outside.
High durability: If manufactured from good quality materials, the joint can be as durable as the pipe itself.
