另外，通风管道的应用途径特别广泛，其中在室外的应用也是非常多见的。

In addition, the application of ventilation ducts is particularly extensive, especially in outdoor applications.

所以，对于一些在室外使用的通风管道来说，一定要具备比较好的抗腐蚀性，同时市场上的通风管道设备也以金属材质居多，那么，这些金属材质的设备也需要具有比较好的抗氧化性。如果一些金属设备非常容易氧化，随着氧化的日益严重，也会加快管道的损坏。

Therefore, some ventilation pipes used outdoors must have good corrosion resistance. At the same time, most of the ventilation pipes and equipment on the market are made of metal materials. Therefore, these metal equipment also need to have good oxidation resistance. If some metal equipment is very easy to be oxidized, the pipeline damage will be accelerated with the increasingly serious oxidation.
