其實我們都知道，通風管是中空的，一般都是用來通風的一種管材，一般都是圓形或者方形的，通風管道的加工對風管的要求也是非常的大，這樣也是為了操作人員的，所以在對通風管道加工安裝的時候一些問題是一定要注意的，那么在加工的時候要注意哪些內容呢?接下來山東通風管道加工廠家總結這六點，大家一定要注意。

In fact, we all know that the ventilation pipe is hollow, which is generally a kind of pipe used for ventilation. It is generally round or square. The processing of the ventilation pipe also requires a lot of air pipes, which is also for the safety of operators. Therefore, some problems must be paid attention to during the processing and installation of the ventilation pipe. What should be paid attention to during the processing? Next, Shandong ventilation pipe processing factory summarizes these six points, which we must pay attention to.

1、通風管道加工的過程中應該盡量避免出現縱向接縫，但是一定不能出現橫向接縫。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 the ventilation pipe, 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、玻璃纖維復合板風管端口為切割面時，在裝配法蘭連接件前應將管端切口面用膠帶或膠液進行封堵，才能防止玻璃纖維外露和飛散。

5. When the end of the fiberglass composite board air duct is the cutting surface, the cut surface of the duct end shall be sealed with tape or glue before assembling the flange connector to prevent the fiberglass from being exposed and flying away.

6、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。

6. 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.
