Usually high-rise buildings are used for residential buildings, commerce, or office. In these buildings, Jinan ventilation pipeline project plays a vital role, and the quality of ventilation pipeline is directly related to the quality of the whole project. In ventilation duct engineering, galvanized air duct and double-sided color plate composite air duct are often used. The following small braid is to stop the comparison between galvanized air duct and double-sided color plate composite air duct. Friends in need can create their own.
1. Comparing stiffness, strength and bearing capacity
The thickness of galvanized air duct iron sheet can be adjusted according to pipe diameter only when the stiffness, strength and pressure are under pressure. Flanges and flange frames are used to reinforce the galvanized air duct iron sheet, so that the stiffness, strength and pressure are good.
The stiffness, strength and pressure-bearing ability of double-sided color-plate composite duct are slightly lower than those of galvanized duct.
2. Weight comparison
The galvanized air duct is heavier in weight.
Double-sided color plate composite air duct is slightly lighter.
3. Resistance comparison
The inner wall of friction galvanized duct is smooth and the resistance is very small.
The flange of double-sided color-plate composite air duct protrudes into the air duct, and the resistance increases.
4. Appearance comparison
Appearance galvanized duct air duct and flange are insulated, appearance is different.
Colored plate air duct, beautiful appearance.
5. Comparisons of Tightness
The air leakage of galvanized air duct is closely bitten, the seams are sealed, and the air leakage is lower than the standard specification.
Double-sided color plate composite air duct machine processing, small air leakage.
Therefore, after the introduction of galvanized ducts and double-sided color plate composite ducts, I believe that you should be able to choose the appropriate ducts according to my needs. Of course, in Jinan ventilation pipeline project, we also need to strictly check the quality of ventilation pipeline equipment.
