Ventilation pipe is an important ventilation facility for buildings and factories. It can adjust the indoor air and keep the indoor air humidity. So how to repair the damaged ventilation pipe? Let's see what the manufacturer of ventilation pipe says.

如果是通風管道外表面很輕微的破損，可以用專用的密封膠帶來進行修補即可。如果是通風管道內表面有輕微破損，則可用專用修補膠進行修補。如果通風管道外表面的鋁箔層發生破損，而玻纖保溫層未發生損壞，則可選用一片合格的鋁箔片進行管道鋁箔表面的修補。

If the outer surface of the ventilation pipe is slightly damaged, it can be repaired with special sealing tape. If the inner surface of the ventilation pipe is slightly damaged, it can be repaired with special repair glue. If the aluminum foil layer on the outer surface of the ventilation pipe is damaged, and the glass fiber insulation layer is not damaged, a qualified aluminum foil can be selected to repair the aluminum foil surface of the pipe.、

如果通風管道壁的破損已達到玻纖保溫層時，則可將破損的地方切割下來，開出雌雄搭接口，另選一塊完好的板材，根據切割下來的玻板尺寸切割好，留下雌雄搭接口，在四周接口上涂上修補膠及粘膠劑，根據工藝規范進行密封。

If the damage of the ventilation pipe wall has reached the glass fiber insulation layer, the damaged place can be cut down, the male and female joints can be opened, and another intact plate can be selected. According to the size of the cut glass plate, the male and female joints can be left, and the joints around can be coated with repair glue and adhesive, and sealed according to the process specification.

如果通風管道的破損比較嚴重，且破損面積比較大，有可能會影響通風管道系統的正常運行時，就需要對管道進行更換修補，以保證系統的正常運行。

If the damage of the ventilation pipe is serious and the damage area is large, which may affect the normal operation of the ventilation pipe system, it is necessary to replace and repair the pipe to ensure the normal operation of the system.

如果不是大面積的破損，進行必要的日常修補就可以了，在修補的時候建議是請專門的人員進行操作。

If it is not a large area of damage, it is necessary to carry out daily repair. It is recommended to ask special personnel to operate when repairing.
