螺旋风管其长度等方面是要好于矩形风管：这是由于普通的螺旋风管，其正常长度是为3米到6米，而矩形风管其是为1米到1.5米，除此之外，螺旋风管的长度，还能够依照具体需求来定做，从其它方面来看，螺旋风管中的连接点，是能够很大程度上根绝的，由于其风管之间的连接，只用管接件，而矩形风管则需求双法兰体系。

The length and other aspects of spiral ducts are better than rectangular ducts: this is because ordinary spiral ducts have a normal length of 3 to 6 meters, while rectangular ducts have a length of 1 to 1.5 meters. In addition, the length of spiral ducts can be customized according to specific needs. From other aspects, the connection points in spiral ducts can be largely eliminated. Due to the connection between ducts, only pipe connectors are used, Rectangular air ducts require a double flange system.

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。

During the processing of ventilation ducts, longitudinal joints should be avoided as much as possible, but transverse joints must not occur. Moreover, the bite seams and corners of the ventilation ducts need to be sealed tightly with sealant according to the design cleanliness level requirements. In addition, the sealing surface of the connection joint of the ventilation duct board should be set on the positive pressure side of the ventilation duct wall.

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。

During processing, reinforcement frames or ribs should not be installed inside the ventilation ducts, as this will have a certain impact on the quality of the ventilation ducts.

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。

The connection method of S-shaped and C-shaped right angle inserts cannot be used for the processing of ventilation ducts. Additionally, for some special ventilation ducts, a snap fit cannot be used.

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。

After the production of the ventilation duct is completed, it needs to be cleaned with cleaning solution. Only after reaching the cleaning standard can it be sealed in a timely manner.
