Our company has reached strategic cooperation with a Malaysian ventilation duct manufacturer

What are the layout requirements for galvanized ventilation ducts? What are the renovation plans?

1. The air duct of the galvanized ventilation duct dust removal system should be made of round steel air duct, and its joints and seams should be tight.

2. Galvanized ventilation ducts should be installed vertically or at an angle. When installed obliquely, the intersection angle between the air duct and the plane should exceed 45°, pipe sections with slight inclination or horizontal laying should be reduced as much as possible, and measures to avoid smoke and dust accumulation should be adopted.

3. The galvanized ventilation pipe riser needs to be inserted from the top or side of the person in charge, and the intersection angle of the tee should be between 15-45 degrees.

4. Galvanized ventilation ducts are equipped with closed cleaning holes around special-shaped pipe fittings that are prone to dust accumulation.

5. The angle between the corners of the dust removal air duct of the galvanized ventilation duct is r=1.5-3.0d. If the included angle is not allowed to be large, guide vanes should be set at the elbow.
