在建筑業快速發展的現在，高層建筑越來越多，為了保護在內工作人員的身體健康，通風管道的運用也多了起來，在給通風管道加工時，有很多事項要注意，下面山東通風管道加工人員來講解主要是一些常見的問題。

With the rapid development of the construction industry, there are more and more high-rise buildings. In order to protect the health of the staff inside, more ventilation pipes are used. When processing ventilation pipes, there are many things to pay attention to. Next, Shandong ventilation pipe processing personnel will explain some common problems.

1、通風管道加工的過程中應該盡量避免出現縱向接縫，但是不能出現橫向接縫。而且通風管道的咬口縫和四角的縫隙處，需要按照設計潔凈等級要求，然后還要采用密封膠將其堵嚴。另外通風管道板材的連接縫的密封面應該設在通風管道壁的正壓側。

1. The longitudinal joint shall be avoided as far as possible during the processing of ventilation duct, but the transverse joint shall not be allowed. Moreover, the seaming seams and the four corners of the ventilation pipe shall be sealed with sealant according to the design cleanliness level requirements. In addition, the sealing surface of the joint of the ventilation duct plate should be set at the positive pressure side of the ventilation duct wall.

2、加工的時候，不能在通風管道內部設置加固框或者加固筋，因為這樣對于通風管道的質量會造成一定的影響。

2. During processing, reinforcing frames or reinforcements cannot be set inside the ventilation ducts, because this will have a certain impact on the quality of the ventilation ducts.

3、通風管道加工不能采用S型插條和C型直角插條的連接方式，另外對于一些特殊的通風管道來說，還不能采用按扣式的咬口。

3. The connection mode of S-shaped and C-shaped right angle inserts cannot be used for the processing of ventilation ducts. In addition, snap joint cannot be used for some special ventilation ducts.

4、通風管道制作完畢之后，還要用清洗液進行清洗，只有達到清洗標準之后，才可以及時封口。

4. After the fabrication of the ventilation pipe, it shall be cleaned with cleaning solution. Only when the cleaning standard is met, can it be sealed in time.

5、如果是彩色涂層鋼板通風管道的話，應該保持內壁是光滑的，而且通風管道加工的過程中，還不能將涂層損壞，若是出現損壞的部位，需要用環氧樹脂涂刷在表面即可。另外通風管道加工的過程中，還要做好防腐蝕措施，不能使用抽芯鉚釘，而且在通風管道零件裝配的時候，這些零件都要經過鍍鋅處理才行。

5. If it is a color coated steel plate ventilation duct, the inner wall should be kept smooth, and the coating should not be damaged during the processing of the ventilation duct. In case of damaged parts, epoxy resin should be applied to the surface. In addition, anti-corrosion measures shall be taken during the processing of the ventilation pipe, and pop rivets shall not be used. In addition, these parts shall be galvanized during the assembly of the ventilation pipe parts.
