1.大口径螺旋风管，其在进行计算时，在计算要素上，是否与普通的螺旋风管一样？

1. Is the calculation element of large-diameter spiral air ducts the same as that of ordinary spiral air ducts?

大口径螺旋风管，其在进行计算时的计算要素，从角度来讲，与普通的螺旋风管是一样的，都是为流量、单位摩擦阻力、雷诺数和摩擦阻力系数这四个，其中的流量，又可以是为风量。而且，对这一点，应有正确认识，并牢记于心。

From a professional perspective, the calculation elements for large-diameter spiral air ducts are the same as those for ordinary spiral air ducts, which are flow rate, unit frictional resistance, Reynolds number, and frictional resistance coefficient. The flow rate can also be air volume. Moreover, it is important to have a correct understanding of this and keep it in mind.

2.为何大口径螺旋风管能保证在1.5倍工作压力下，其接缝处不会出现开裂这一问题？

Why can large-diameter spiral air ducts ensure that there will be no cracking at their joints under 1.5 times the working pressure?

这个问题，如果让技术人员来回答的话，那么，它们给出的具体答案，是为：因为，大口径螺旋风管，其与普通的螺旋风管一样，其接缝是周向的，因此接缝强度要高于径向的直缝强度，而且要高很多，所以，在1.5倍的工作压力下，其能够保证不出现开裂这一问题。

If professional technicians were to answer this question, their specific answer would be: because large-diameter spiral air ducts, like ordinary spiral air ducts, have circumferential seams, so the seam strength is higher than the radial straight seam strength, and much higher. Therefore, under 1.5 times the working pressure, they can ensure that cracking does not occur.

3.大口径螺旋风管，其适合在大口径管道中使用吗？此外，其材质是否和口径大小有关？

3. Is large-diameter spiral air duct suitable for use in large-diameter pipelines? In addition, is its material related to the caliber size?

大口径螺旋风管，其适合在大口径管道中使用，因为，这一种风管是用材料进行卷制并一次成型的，所以，适合在大口径管道中使用。而且，其的耐压性能，也是非常好的。

Large diameter spiral air ducts are suitable for use in large diameter pipelines because they are rolled and formed in one go using materials. Therefore, they are suitable for use in large diameter pipelines. Moreover, its voltage resistance performance is also very good.

大口径螺旋风管的材质，其与口径大小是否有关，从角度来讲，这两个是没有任何关系的，而且，是这一种螺旋风管的不同方面，所以，在其口径大小的确定上，是不需要考虑风管材质这一具体方面的，可根据实际情况和使用要求，选择合适材质。

The material of large-diameter spiral air ducts is not related to the diameter from a professional perspective, and they are different aspects of this type of spiral air duct. Therefore, in determining the diameter size, there is no need to consider the specific aspect of air duct material. Suitable materials can be selected according to the actual situation and usage requirements.
