　　1. 圓管通常為直裝管，打標時應明確標注其直徑;

　　1. The round pipe is usually straight mounted, and its diameter shall be clearly marked during marking;

　　2. 矩形通風道一般在施工過程中建造，長度和寬度清晰;

　　2. The rectangular ventilation channel is generally built in the construction process, with clear length and width;

　　3、外型為長方形，內切圓，這種管子是裝完后將管粉倒入外面，標記后只需要標記長度和寬度。

　　3. The outer shape is rectangular and the inner part is round. After the pipe is installed, pour the pipe powder into the outer part. After marking, only the length and width need to be marked.
