　　4, air duct installation, into and out of the open hole in the air duct should be prefabricated, if installed in the air duct on the open air, the interface should be tight.

　　5、雙吊桿支架在風道就位后，應保證橫擔平直，吊桿不扭轉，雙吊桿受力均勻。

　　5, the double boom support in the wind in place, should ensure that the cross arm flat, the boom is not reversed, double boom uniform force.

　　6、當輸送含凝結水或含濕量較大的氣體時，其水平管道宜設有坡度，并在低點處接排水管。安裝時風道底部不宜出現縱向接縫，對底部有接縫處應進行密封處理。

　　6, when conveying water containing condensate or larger moisture content, the horizontal pipeline should have a slope, and at the low point to connect the drain pipe. The longitudinal joint should not be installed at the bottom of the air duct, and the joints at the bottom should be sealed.

　　7、對輸送易燃、易爆氣體的鋼板風道，在風道連接法蘭處應安裝跨接線，并與靜電接地網連接。

　　7, the transmission of flammable and explosive gas steel plate air duct, in the air duct connecting flange should be installed across the wiring, and connected with the electrostatic grounding grid.
