　　通风管是中空的用于通风的管材，多为圆形或方形。通风管道的加工对以后风管的使用有很大的影响，也为了操作人员的，所以了解清楚通风管道的加工安装注意事项十分必要，小编特整理了相关资料分享给大家，在给通风管道加工时，有很多事项要注意，下面主要是一些常见的问题：

　　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.通风管道加工的过程中应该尽量避免出现纵向接缝，但是一定不能出现横向接缝。而且通风管道的咬口缝和四角的缝隙处，需要按照设计洁净等级要求，然后还要采用密封胶将其堵严。另外通风管道板材的连接缝的密封面应该设在通风管道壁的正压侧。

　　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.加工的时候，不能在通风管道内部设置加固框或者加固筋，因为这样对于通风管道的质量会造成一定的影响。

　　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.通风管道加工不能采用S型插条和C型直角插条的连接方式，另外对于一些特殊的通风管道来说，还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.通风管道制作完毕之后，还要用清洗液进行清洗，只有达到清洗标准之后，才可以及时封口。

　　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.玻璃纤维复合板风管端口为切割面时，在装配法兰连接件前应将管端切口面用胶带或胶液进行封堵，才能防止玻璃纤维外露和飞散。

　　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.如果是彩色涂层钢板通风管道的话，应该保持内壁是光滑的，而且通风管道加工的过程中，还不能将涂层损坏，若是出现损坏的部位，需要用环氧树脂涂刷在表面即可。另外通风管道加工的过程中，还要做好防腐蚀措施，不能使用抽芯铆钉，而且在通风管道零件装配的时候，这些零件都要经过镀锌处理才行。

　　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.
