　　通風(fēng)管是中空的用于通風(fēng)的管材，多為圓形或方形。通風(fēng)管道的加工對以后風(fēng)管的使用有很大的影響，也為了操作人員的，所以了解清楚通風(fēng)管道的加工安裝注意事項(xiàng)十分必要，小編特整理了相關(guān)資料分享給大家，在給通風(fēng)管道加工時(shí)，有很多事項(xiàng)要注意，下面主要是一些常見的問題：

　　Ventilation pipe is a hollow pipe used for ventilation, mostly round or square. The processing of ventilation duct has a great impact on the use of air duct in the future, and also for the safety of operators. Therefore, it is necessary to understand the precautions for the processing and installation of the ventilation duct. The small editor has sorted out the relevant information and shared it with you. When processing the ventilation duct, there are many things to pay attention to. The following are some common problems:

　　1.通風(fēng)管道加工的過程中應(yīng)該盡量避免出現(xiàn)縱向接縫，但是一定不能出現(xiàn)橫向接縫。而且通風(fēng)管道的咬口縫和四角的縫隙處，需要按照設(shè)計(jì)潔凈等級要求，然后還要采用密封膠將其堵嚴(yán)。另外通風(fēng)管道板材的連接縫的密封面應(yīng)該設(shè)在通風(fēng)管道壁的正壓側(cè)。

　　However, the transverse joint should not appear in the process of ventilation. Moreover, the bite seam and four corners of the ventilation pipe need to be in accordance with the requirements of the design cleanliness level, and then the sealant should be used to block it tightly. In addition, the sealing surface of the joint of the ventilation pipe plate should be set on the positive pressure side of the ventilation pipe wall.

　　2.加工的時(shí)候，不能在通風(fēng)管道內(nèi)部設(shè)置加固框或者加固筋，因?yàn)檫@樣對于通風(fēng)管道的質(zhì)量會(huì)造成一定的影響。

　　2. When processing, it is not allowed to set the reinforcement frame or reinforcement bar inside the ventilation pipe, because it will have a certain impact on the quality of the ventilation pipe.

　　3.通風(fēng)管道加工不能采用S型插條和C型直角插條的連接方式，另外對于一些特殊的通風(fēng)管道來說，還不能采用按扣式的咬口。

　　3. The connection mode of S-shaped insert and C-type right angle socket cannot be used in the processing of ventilation pipe. In addition, for some special ventilation pipes, the snap on bite can not be used.

　　4.通風(fēng)管道制作完畢之后，還要用清洗液進(jìn)行清洗，只有達(dá)到清洗標(biāo)準(zhǔn)之后，才可以及時(shí)封口。

　　4. After the ventilation pipe is made, it should be cleaned with cleaning solution. Only when it reaches the cleaning standard can it be sealed in time.

　　5.玻璃纖維復(fù)合板風(fēng)管端口為切割面時(shí)，在裝配法蘭連接件前應(yīng)將管端切口面用膠帶或膠液進(jìn)行封堵，才能防止玻璃纖維外露和飛散。

　　5. When the air duct end of glass fiber composite board is the cutting surface, the cutting surface of the pipe end should be blocked with tape or glue before assembling the flange connector, so as to prevent the glass fiber from being exposed and flying away.

　　6.如果是彩色涂層鋼板通風(fēng)管道的話，應(yīng)該保持內(nèi)壁是光滑的，而且通風(fēng)管道加工的過程中，還不能將涂層損壞，若是出現(xiàn)損壞的部位，需要用環(huán)氧樹脂涂刷在表面即可。另外通風(fēng)管道加工的過程中，還要做好防腐蝕措施，不能使用抽芯鉚釘，而且在通風(fēng)管道零件裝配的時(shí)候，這些零件都要經(jīng)過鍍鋅處理才行。

　　6. If it is a color coated steel ventilation pipe, the inner wall should be kept smooth, and the coating should not be damaged during the processing of the ventilation pipe. If the damaged part occurs, it is necessary to brush the surface with epoxy resin. In addition, in the process of ventilation pipe processing, anti-corrosion measures should be taken, and core pulling rivets should not be used. Moreover, when the ventilation pipe parts are assembled, these parts should be galvanized.
