通风管道主要应用在工业及建筑工程中，应用领域主要涉及：电子工业无尘厂房净化系统，医药食品无菌车间净化系统，酒店宾馆、医院、工厂及写字楼的空调系统，工业污染控制用除尘、排烟、吸油等排风管、工业环境或岗位用送风管、煤矿抽放瓦斯用抽放瓦斯系统、煤矿矿井环境控制用送回风系统等等;
Ventilation ducts are mainly used in industrial and construction projects. The application fields mainly involve: dust-free workshop purification system in electronic industry, sterile workshop purification system in medicine and food, air conditioning system in hotels, shopping malls, hospitals, factories and office buildings, exhaust pipes for dust removal, smoke exhaust and oil absorption for industrial pollution control, air supply pipes for industrial environment or posts Gas drainage system for coal mine gas drainage, air supply and return system for coal mine environmental control, etc;

(5) 提供室内燃烧设备燃烧所需要的空气。
(5) Provide air required for combustion of indoor combustion equipment.
通风管道的截面有三种形状，下面由*人员介绍一下：
The cross section of the ventilation duct has three shapes, which are introduced by * personnel below:
1、圆形的，圆形管道一般是直接装的管子，标注时要标清其直径;
1. Circular pipes are generally directly installed pipes, and their diameters shall be marked clearly when marking;
2、矩形的，矩形的通风管道一般是建筑施工时砌成的，标注时标清长和宽;
2. Rectangular, rectangular ventilation pipes are generally built during construction, and the length and width shall be marked clearly when marking;
3、外观是矩形的，里面内切圆，这种管道是装好管子后后期外粉成的，标注时也只需标清长和宽。
3. The appearance is rectangular and the inside is inscribed round. This kind of pipe is made of external powder after the pipe is installed. When marking, only the length and width need to be marked.
