In recent years, with the continuous progress of people's living standards, people's health awareness is getting higher and higher. Ventilation equipment has entered the office building and become an indispensable part of people's daily life. The hot sale of ventilation equipment has promoted the development of ventilation equipment technology, making the equipment technology of ventilation equipment better and better. However, it is inevitable that the ventilation pipe will be damaged when the equipment is installed. Next, we will explain how to deal with the problem of ventilation pipe damage.

如果在管道外就用專用的密封膠就可以修補，管道表面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 special sealant is used outside the pipe to repair, and the aluminum foil layer on the surface of the pipe is damaged, but the glass fiber insulation layer is not damaged, a qualified aluminum foil can be selected to repair the aluminum foil surface of the pipe.

如果在通風設備設備時發現破損已達到玻纖保溫層時，則可將破損的當地切開下來，另選一塊無缺的板材，根據切開下來的玻板標準切開好，然后在四周接口上涂上修補膠及粘膠劑，根據工藝標準進行密封，在通風設備正常作業時就要常常檢查防止耽擱作業。

If it is found during the ventilation equipment that the damage has reached the glass fiber insulation layer, the damaged area can be cut down, another intact plate can be selected, cut according to the cut glass plate standard, and then apply repair glue and adhesive on the interface around, seal according to the process standard, and often check to prevent delay in the normal operation of the ventilation equipment.

通風管道用途的區分：

Differentiation of ventilation duct use:

1、凈化空調系統用風管：鍍鋅板、不銹鋼；（運用中可能出現塵源污染的玻璃鋼、復合材料禁用）

1. Air duct for purification air conditioning system: galvanized sheet, stainless steel; (FRP and composite materials that may cause dust source pollution during operation are prohibited)

2、空調系統用風管：鍍鋅板、彩鋼保溫板；（通風管道可運用玻璃鋼、復合材料）

2. Air duct for central air-conditioning system: galvanized sheet, color steel insulation board; (FRP and composite materials can be used for ventilation ducts)

3、環境操控系統用風管：鍍鋅板、不銹鋼；（可運用塑料、玻璃鋼、復合材料）

3. Air duct for environmental control system: galvanized sheet, stainless steel; (Plastic, glass fiber reinforced plastic and composite materials can be used)

4、工業通風系統用風管：鋼板、鍍鋅板；（通風管.可運用塑料、玻璃鋼、復合材料）

4. Air duct for industrial ventilation system: steel plate, galvanized plate; (Vent pipe. Plastic, glass fiber reinforced plastic and composite materials can be used)

注：玻璃鋼風管可分有機、無機二種，根據設計標準有消防要求的禁用有機質料；

Note: FRP air duct can be divided into organic and inorganic materials. Organic materials with fire protection requirements according to design standards are prohibited;

5、特別運用場合用風管：礦用涂膠布風筒、礦用塑料通風管；（要求阻燃抗靜電礦用特性）

5. Air ducts for special applications: rubber coated mine air ducts, plastic mine air ducts; (Flame retardant and anti-static mining safety characteristics are required)
