1. Clamp type connection
Mainly used for connecting steel plate circular air ducts and spiral air ducts. During installation, insert the small opening into the large opening according to the direction of airflow, and use steel clamps to tightly connect the two ends of the drum clamps. Use bolts to fix and tighten them in the middle of the earrings.
2. Plug in connection
Mainly used for connecting rectangular or circular ducts. First, make the connecting pipe, then insert the air ducts on both sides, and tightly fix them with rivets.
3. Insert style connection
Mainly used for connecting rectangular ducts. Insert different forms of inserts into both ends of the air duct and compact them.
4. Flexible hose connection
Mainly used for connecting air ducts and components. During installation, the two ends of the hose should be placed outside the connected pipe, and then the hose should be tightened with a special soft clamp.
If it is the connection of the smoke exhaust duct, the smoke exhaust duct should still be welded (especially the horizontal pipe, and the slope of the pipe should be ensured to facilitate oil leakage) to avoid oil and gas leakage and ensure project quality. However, due to the high temperature gas inside the smoke exhaust duct, direct butt welding may also cause expansion and cracking during use. In actual construction, full welding of the flange can be done, and it should not be a right angled flange to ensure that it is not affected by the thermal expansion and contraction of the duct, and also to strengthen the duct.

Stainless steel spiral duct is a thin-walled pipe made of metal strip material rolled into a spiral groove, usually circular, unwelded, leak proof, and leak proof. This type of air duct is produced using a full mechanism, and straight pipes do not require manual tapping, resulting in high production efficiency and accuracy.

Characteristics and advantages

Good corrosion resistance: Stainless steel material has natural corrosion resistance and can be used for a long time in harsh environments such as humidity, acidity, and alkalinity without rusting, making it suitable for various industrial and commercial applications.
High strength and durability: Stainless steel spiral ducts have high mechanical strength and durability, can withstand large external pressure and internal airflow pressure, are not easily deformed or damaged, and have a long service life.
Good sealing performance: The spiral design enables stainless steel ducts to have good sealing performance, reducing the risk of gas leakage and improving the operational efficiency of the system.
Beautiful and elegant: Stainless steel air ducts have a smooth surface and a beautiful and elegant appearance, suitable for installation in places with high requirements for appearance, such as commercial buildings, public facilities, etc.
Easy to clean and maintain: Stainless steel material is not prone to dirt and is easy to clean and maintain, helping to maintain the hygiene and air quality of ventilation systems.
Easy installation: Stainless steel spiral air ducts are relatively lightweight, with good processability and installation convenience. They can be cut and adjusted according to on-site needs, saving installation time and costs.
