专注通风管道加工·排烟罩

其实我们都知道，通风管是中空的，一般都是用来通风的一种管材，一般都是圆形或者方形的，通风管道的加工对风管的要求也是非常的大，这样也是为了操作人员的，所以在对通风管道加工安装的时候一些问题是一定要注意的，那么在加工的时候要注意哪些内容呢?接下来山东通风管道加工厂家总结这六点，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、通风管道加工的过程中应该尽量避免出现纵向接缝，但是一定不能出现横向接缝。而且通风管道的咬口缝和四角的缝隙处，需要按照设计洁净等级要求，然后还要采用密封胶将其堵严。另外通风管道板材的连接缝的密封面应该设在通风管道壁的正压侧。

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、加工的时候，不能在通风管道内部设置加固框或者加固筋，因为这样对于通风管道的质量会造成一定的影响。

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、通风管道加工不能采用S型插条和C型直角插条的连接方式，另外对于一些特殊的通风管道来说，还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、通风管道制作完毕之后，还要用清洗液进行清洗，只有达到清洗标准之后，才可以及时封口。

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、玻璃纤维复合板风管端口为切割面时，在装配法兰连接件前应将管端切口面用胶带或胶液进行封堵，才能防止玻璃纤维外露和飞散。

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、如果是彩色涂层钢板通风管道的话，应该保持内壁是光滑的，而且通风管道加工的过程中，还不能将涂层损坏，若是出现损坏的部位，需要用环氧树脂涂刷在表面即可。另外通风管道加工的过程中，还要做好防腐蚀措施，不能使用抽芯铆钉，而且在通风管道零件装配的时候，这些零件都要经过镀锌处理才行。

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.
