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、剛度、強度及承壓才能比照

　　1. Comparing stiffness, strength and bearing capacity

　　剛度、強度及承壓才能鍍鋅風管鐵皮厚度依據管徑相應調整，采用法蘭及法蘭框加固，剛度、強度及承壓才能好。

　　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.

　　雙面彩板復合風管剛度、強度及承壓才能均略低于鍍鋅風管。

　　The stiffness, strength and pressure-bearing ability of double-sided color-plate composite duct are slightly lower than those of galvanized duct.

　　2、重量比照

　　2. Weight comparison

　　重量鍍鋅風管較重。

　　The galvanized air duct is heavier in weight.

　　雙面彩板復合風管略輕。

　　Double-sided color plate composite air duct is slightly lighter.

　　3、阻力比照

　　3. Resistance comparison

　　沿程摩阻鍍鋅風管內壁平滑，阻力極小。

　　The inner wall of friction galvanized duct is smooth and the resistance is very small.

　　雙面彩板復合風管法蘭凸入風管內，阻力增加。

　　The flange of double-sided color-plate composite air duct protrudes into the air duct, and the resistance increases.

　　4、外觀比照

　　4. Appearance comparison

　　外觀鍍鋅風管風管及法蘭均保溫，外觀分歧。

　　Appearance galvanized duct air duct and flange are insulated, appearance is different.

　　彩板風管，外觀美觀。

　　Colored plate air duct, beautiful appearance.

　　5、嚴密性比照

　　5. Comparisons of Tightness

　　漏風量鍍鋅風管咬口緊密，接縫采取密封措施，漏風量低于標準規范。

　　The air leakage of galvanized air duct is closely bitten, the seams are sealed, and the air leakage is lower than the standard specification.

　　雙面彩板復合風管機器加工，漏風量小。

　　Double-sided color plate composite air duct machine processing, small air leakage.

　　因而，經過小編為大家引見的鍍鋅風管與雙面彩板復合風管，置信大家應該能夠依據本人的需求，選擇合適本人的風管了。當然在濟南通風管道工程中，還需求嚴厲把關通風管道裝置質量。

　　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.
