Timely dust removal of the pipe can ensure the use effect of the pipe.

3、安裝時要注意細節。在將通風管道拿向高處進行就位前，工作人員可以先在地面上將通風管道分段組裝完成。在安裝通風管道的過程當中，工作人員對于每一個孔洞的位置和尺寸要事先預留出來，然后使用法蘭螺栓將其擰緊。

3. Pay attention to details during installation. Before taking the ventilation pipe to a high place, the staff can assemble the ventilation pipe on the ground in sections. During the installation of the ventilation pipe, the staff should reserve the position and size of each hole in advance, and then use flange bolts to tighten it.

要保證螺帽的朝向一致，同時還要保證通風管道的垂直度，按照施工標準將這些通風管道固定住。然后再將上面的電線等固定。保證通風管道達到安裝的要求。一般情況下，專門的公司會對安裝人員進行培訓，促使工作人員在安裝通風管道的時候主動留意這些要點。
