另外，通風管道的應用途徑特別廣泛，其中在室外的應用也是非常多見的。

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

所以，對于一些在室外使用的通風管道來說，一定要具備比較好的抗腐蝕性，同時市場上的通風管道設備也以金屬材質居多，那么，這些金屬材質的設備也需要具有比較好的抗氧化性。如果一些金屬設備非常容易氧化，隨著氧化的日益嚴重，也會加快管道的損壞。

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.
