What accounts for the majority in duct processing?

大部分是现在吵得沸沸扬扬的数螺旋风管了吧。在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。

Most of them are now noisy spiral cyclone tubes. The length of spiral air duct is better than that of rectangular air duct: this is because the normal length of ordinary spiral air duct is 3 to 6 meters, while that of rectangular air duct is 1 to 1.5 meters. In addition, the length of spiral air duct can also be customized according to specific needs. From other aspects, the connection points in spiral air duct can be eliminated to a large extent, because the connection between air ducts is only pipe connectors, The rectangular air duct requires double flange system.

相对于螺旋风管其出产制作能够获取批量化制作吗?

Compared with spiral air duct, can its production and production be mass produced?

这个话，对螺旋风管是毫无其它疑问的，由于从如今来看，该风管的制作，已经获取了体系化和智能化，并且在质量控制上，也能够做到非常好，因而获取批量化制作，是毫无疑问的，还能够做到有好的产品质量。

In this case, there is no doubt about the spiral air duct. From now on, the production of the air duct has been systematic and intelligent, and the quality control can also be very good. Therefore, there is no doubt that the batch production can be obtained, and good product quality can be achieved.

在咬口成型技术上，螺旋风管，是运用了怎样的技术：

In terms of seaming forming technology, what kind of technology is used for spiral air duct:

螺旋风管的咬口成型技术，关键的是运用模具来进行完成的，由于其限制模具表面能够长时间保持不变，因而大大增长了风管的运用年限，并且，在其密封性能、连接强度与咬口紧密度上，也是有好的表现的。

The key to the seam forming technology of spiral air duct is to use the mold to complete it. Because it limits the mold surface to remain unchanged for a long time, it greatly increases the service life of the air duct, and it also has good performance in its sealing performance, connection strength and seam tightness.
