濟南風管加工就是為了使空氣流通而制作的一種物品，其特點以及優勢就是為了能夠達到通風，增強空氣的流通性，其材質的選用上一般都是采用的型材或者板材為主要材料。在通風管道加工過程中常會遇見很多問題，就這些需要注意的問題我們為大家整理一下，以備不時之需。

Jinan air duct processing is a kind of goods made for the purpose of air circulation. Its characteristics and advantages are to achieve ventilation and enhance the air circulation. The material of Jinan air duct processing is usually made of profiles or sheets. In the process of ventilation pipe processing, we often meet many problems, on these issues we need to pay attention to tidy up for you, in case of occasional needs.

關于通風管道加工過程中應注意的問題：

The problems that should be paid attention to in the process of ventilation pipeline processing are as follows:

1.風管加工連接螺栓、螺母、墊圈和鉚釘應采用鍍鋅或其他防腐措施，不得使用抽芯鉚釘。

1. Galvanizing or other anti-corrosion measures shall be adopted for connecting bolts, nuts, washers and rivets in air duct processing, and core-pulling rivets shall not be used.

2.凈化空調系統風管的法蘭鉚釘間距應小于100 mm，空氣潔凈等級為1～5的風管法蘭鉚釘間距應小于65mm。

2. The flange rivet spacing of air duct in purified air conditioning system should be less than 100 mm, and that of air duct flange rivet spacing of air cleanliness grade 1-5 should be less than 65 mm.

3. 風管內不得設置加固框或加固筋。

3. Reinforcement frames or reinforcement bars shall not be installed in ducts.

4.通風管道制作完畢應使用清洗液清洗，清洗后經白綢布擦拭檢查達到要求后，酚醛板，應及時封口。

4. Ventilation pipes should be cleaned with cleaning solution after production. After cleaning, the phenolic board should be sealed in time after the requirements are met by the white silk cloth wiping inspection.

5.風管加工前應采用清洗液去除板材表面油污及積塵，清洗液應采用對板材表面無損害、干燥后不產生粉塵，且對人體無危害的中性清潔劑。

5. Before air duct processing, cleaning fluid should be used to remove oil and dust on the surface of sheet metal. Cleaning fluid should be neutral detergent which is harmless to the surface of sheet metal, does not produce dust after drying, and does not harm to human body.

6.彩色涂層鋼板風管的內壁應光滑;板材加工時不得損壞涂層，被損壞的部位應涂環氧樹脂。

6. The inner wall of the air duct of the color coated steel plate shall be smooth; the coatings shall not be damaged during the processing of the plate, and the damaged parts shall be coated with epoxy resin.

7.風管制作場所應相對封閉，制作場地宜鋪設不易產生灰塵的軟性材料。

7. Ventilation control workplaces should be relatively closed, and production sites should be laid with soft materials which are not easy to produce dust.

8風管的咬口縫、鉚接縫以及法蘭翻邊四角縫隙處，應按設計及潔凈等級要求，采用涂密封膠或其他密封措施堵嚴。密封材料宜采用異丁基橡膠、氯丁橡膠、變性硅膠等為基材的材料。風管板材連接縫的密封面應設在風管壁的正壓側。

8 The bite seam, rivet seam and flange flange flange corner seam shall be sealed with sealant or other sealing measures according to the requirements of design and cleanliness grade. Isobutyl rubber, chloroprene rubber and modified silica gel are suitable for sealing materials. The sealing surface of the connecting joint of the air pipe sheet should be located at the positive pressure side of the air pipe wall.

9.風管應減少縱向接縫，玻璃鋼通風管道，且不得有橫向接縫。

9. Ventilation pipes should reduce longitudinal joints, FRP ventilation pipes, and no transverse joints.

10.風管不得采用S型插條、C型直角插條及立聯合角插條的連接方式。空氣潔凈等級為1～5級的風管不得采用按扣式咬口。

10. Air ducts shall not be connected by S-type, C-type right-angle and vertical joint-angle inserts. No button bite shall be used for air ducts with air cleanliness grades of 1-5.
