专注通风管道加工·排烟罩

在建筑业快速发展的现在，高层建筑越来越多，为了保护在内工作人员的身体健康，通风管道的运用也多了起来，在给通风管道加工时，有很多事项要注意，下面山东通风管道加工人员来讲解主要是一些常见的问题。

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、通风管道加工的过程中应该尽量避免出现纵向接缝，但是不能出现横向接缝。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 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、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。

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.
