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.
