通風管是用于通風的空心管，多為圓形或方形。風管的加工對以后風管的使用有很大的影響。這也是為了操作者的。因此，有必要了解通風管道的加工和安裝的注意事項。我們整理了相關資料，分享給大家。

Ventilation pipe is a hollow pipe for ventilation, which is mostly round or square. The processing of air duct has a great impact on the use of air duct in the future. This is also for the safety of the operator. Therefore, it is necessary to understand the precautions for the processing and installation of ventilation ducts. We sorted out relevant materials and shared them with you.

1、濟南通風管道加工在這一過程中應盡量避免豎縫，但不得出現橫縫。此外，通風管道的咬縫和縫隙的四個角需要符合設計清潔度要求，然后必須使用密封膠將它們密封嚴密。另外，通風管片連接縫的密封面應設置在通風管壁的正壓側。

1. During the processing of ventilation pipes in Jinan, vertical joints should be avoided as much as possible, but transverse joints are not allowed. In addition, the undercut and the four corners of the gap of the ventilation pipe need to meet the design cleanliness requirements, and then they must be sealed tightly with sealant. In addition, the sealing surface of the joint of the ventilation pipe segment should be set on the positive pressure side of the ventilation pipe wall.

2、在加工過程中，不能在通風管道內設置鋼筋框架或鋼筋，因為這會對通風管道的質量產生一定的影響。

2. During the processing, the reinforcement frame or reinforcement cannot be set in the ventilation duct, because it will have a certain impact on the quality of the ventilation duct.

3、S型嵌件和C型直角嵌件的連接方式不能用于通風管道的加工。此外，對于一些特殊的通風管道，不能使用卡扣式咬合。

3. The connection mode of S-type insert and C-type right angle insert cannot be used for the processing of ventilation duct. In addition, for some special ventilation ducts, snap type bite cannot be used.

4、通風管道制作完成后，應使用清洗液進行清洗。只有達到清潔標準后，才能及時封存。

4. After the ventilation duct is made, it should be cleaned with cleaning fluid. Only after reaching the cleaning standard can it be sealed in time.

5、當玻纖復合板的風管口為切面時，在裝配法蘭連接件前，應在管端切面用膠帶或膠水堵住，防止玻璃纖維外露和散落。

5. When the air duct orifice of the glass fiber composite board is cut, the cut surface of the pipe end should be blocked with tape or glue before assembling the flange connector to prevent the glass fiber from being exposed and scattered.

6、如果是彩涂鋼板風管，內壁應保持光滑，風管加工過程中不得損傷涂層。如果有損壞，需要在表面涂上環氧樹脂能。另外，在風管的加工過程中，必須采取防腐措施，不能使用盲鉚釘，并且在風管部件組裝時，這些部件必須鍍鋅。

6. If the air duct is made of color coated steel plate, the inner wall shall be kept smooth, and the coating shall not be damaged during the processing of the air duct. If there is damage, the surface needs to be coated with epoxy resin. In addition, during the processing of the air duct, anti-corrosion measures must be taken, blind rivets cannot be used, and these parts must be galvanized when the air duct parts are assembled.
