一、通风管道加工的过程中应该尽量避免出现纵向接缝，但是绝对不能出现横向接缝。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。 In the process of pipeline processing, longitudinal joints should be avoided, but horizontal joints must not occur. In addition, the opening of the pipe and the slit of the four corners shall be required according to the design cleanliness level, and then the sealing adhesive shall be used to block the pipe. In addition, the sealing surface of the joints of the ventilation ductwork should be located on the positive side of the wall of the ventilation ducts. 　　二、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。 Second, if is the color coating steel plate ventilation pipe, should keep the lining is smooth, and the process of ventilation pipe processing, also can't coating damage, if it is a case of damage, need to use epoxy resin coating on the surface. Also in the process of the ventilation pipe processing, but also completes the anti-corrosion measures, cannot use core pulling rivets, and at the time of ventilation pipe parts assembly, all these parts will be through galvanized processing. 　　三、通风管道加工的时候，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。 3. When the ventilation pipe is processed, it is not possible to set reinforcement or reinforcing bars inside the ventilation ducts, because it will have a certain effect on the quality of the ventilation ducts. 　　四、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。 4. The process of ventilation ducts cannot be connected with the s-type and c-type rectangular bars, and in addition to some special ventilation ducts, it is not possible to use the button-type bite. 　　五、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。 After the ventilation pipe has been finished, the cleaning solution should be cleaned and only after the cleaning standard is reached can the seal be sealed in time.
