濟(jì)南風(fēng)管加工就是為了使空氣流通而制作的一種物品，其特點(diǎn)以及優(yōu)勢就是為了能夠達(dá)到通風(fēng)，增強(qiáng)空氣的流通性，其材質(zhì)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(fēng)管道加工過程中常會(huì)遇見很多問題，就這些需要注意的問題我們?yōu)榇蠹艺硪幌拢詡洳粫r(shí)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(guān)于通風(fēng)管道加工過程中應(yīng)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(fēng)管加工連接螺栓、螺母、墊圈和鉚釘應(yīng)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(diào)系統(tǒng)風(fēng)管的法蘭鉚釘間距應(yīng)小于100 mm，空氣潔凈等級為1～5的風(fēng)管法蘭鉚釘間距應(yīng)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(fēng)管內(nèi)不得設(shè)置加固框或加固筋。

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

4.通風(fēng)管道制作完畢應(yīng)使用清洗液清洗，清洗后經(jīng)白綢布擦拭檢查達(dá)到要求后，酚醛板，應(yīng)及時(shí)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(fēng)管加工前應(yīng)采用清洗液去除板材表面油污及積塵，清洗液應(yīng)采用對板材表面無損害、干燥后不產(chǎn)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(fēng)管的內(nèi)壁應(yīng)光滑;板材加工時(shí)不得損壞涂層，被損壞的部位應(yīng)涂環(huán)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(fēng)管制作場所應(yīng)相對封閉，制作場地宜鋪設(shè)不易產(chǎn)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(fēng)管的咬口縫、鉚接縫以及法蘭翻邊四角縫隙處，應(yīng)按設(shè)計(jì)及潔凈等級要求，采用涂密封膠或其他密封措施堵嚴(yán)。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(fēng)管板材連接縫的密封面應(yīng)設(shè)在風(fēng)管壁的正壓側(cè)。

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(fēng)管應(yīng)減少縱向接縫，玻璃鋼通風(fēng)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(fēng)管不得采用S型插條、C型直角插條及立聯(lián)合角插條的連接方式?？諝鉂崈舻燃墳?～5級的風(fēng)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.
