通風管道的合口連接是否成功是整個通風管道系統安裝成功與否的關鍵，通風管道的合口連接如果不合格，就會在使管道系統在使用過程中發生泄露的現象。所以說通風管道合口連接時要知道正確的操作，下面濟南通風管道加工人員為您解答。

The success of the joint connection of the ventilation pipe is the key to the success of the installation of the entire ventilation pipe system. If the joint connection of the ventilation pipe is not qualified, the leakage will occur in the use of the pipe system. Therefore, you should know the correct operation when connecting the ventilation pipes. Now, the ventilation pipe processing personnel in Jinan will answer for you.

1、矩形風管直管段，不管是同一板材連接，還是幾塊板材組合拼接，表面需平整、角線順直。組合前應板材切口表面的切割粉末、灰塵及雜物。

1. The straight section of rectangular air duct, whether connected with the same plate or combined with several plates, shall have a flat surface and straight corner lines. Before assembly, the cutting powder, dust and sundries on the cut surface of the plate shall be removed.

2、管段組合后45度角切邊外部接縫，需貼鋁箔膠帶封合板材外殼面，每邊寬度不少于20mm.用角尺、鋼卷尺檢查調整垂直度及對角線偏差，并符合規范要求。

2. After the pipe section is assembled, the outer joint of the 45 ° angle cut edge shall be sealed with aluminum foil tape on the surface of the plate shell. The width of each side shall not be less than 20mm. The perpendicularity and diagonal deviation shall be checked and adjusted with an angle ruler and a steel tape, and shall meet the specification requirements.

3、風管的圓弧面或折線面完成下料并折壓成型后，應與平面板預組合無誤后在涂刷粘合劑，以保證管件的幾何形狀尺寸及觀感。

3. After the arc surface or fold line surface of the air duct is cut and folded, it shall be pre assembled with the plane plate and then coated with adhesive to ensure the geometric shape, size and appearance of the pipe fittings.

4、連接組合后的管段應垂直擺放定型后方可移動。

4. The pipe section after connection and combination shall be placed vertically until it is finalized before moving.

5、鋁箔復合保溫風管所用粘合劑須按板材廠商認定的專用粘合劑，如另行采購粘合劑，須做連接效果對比試驗，并經監理、板材商檢查、認可后方可使用。

5. The adhesive used for aluminum foil composite thermal insulation air duct shall be the special adhesive recognized by the panel manufacturer. If the brand adhesive is purchased separately, the connection effect comparison test shall be conducted, and it can be used only after being checked and approved by the supervisor and the panel manufacturer.

6、粘結前須預組合，檢查接縫全部貼合無誤再涂刷粘合劑，粘合時間控制與季節、溫度及粘合劑性能有關。批量加工前應作樣板試驗，確定合適的粘合時間。

6. Before bonding, pre assembly shall be carried out, and the adhesive shall be applied after all joints are checked for correct adhesion. The bonding time control is related to season, temperature and adhesive performance. Sample test shall be conducted before batch processing to determine proper bonding time.
