通风管道加工的过程中应该尽量防止呈现纵向接缝，可是绝对不能呈现横向接缝。并且通风管道的咬口缝和四角的缝隙处，需要依照设计洁净等级要求，然后还要选用密封胶将其堵严。别的通风管道板材的衔接缝的密封面应该设在通风管道壁的正压侧。
During the processing of ventilation ducts, longitudinal joints should be avoided as much as possible, but transverse joints should never be present. And the bite seams and corners of the ventilation pipeline need to be sealed tightly with sealant according to the design cleanliness level requirements. The sealing surface of the joint of other ventilation duct panels should be set on the positive pressure side of the ventilation duct wall.
二、假如是五颜六色涂层钢板通风管道的话，应该坚持内壁是润滑的，并且通风管道加工的过程中，还不能将涂层损坏，若是呈现损坏的部位，需要用环氧树脂涂刷在表面即可。别的通风管道加工的过程中，还要做好防腐蚀办法，不能运用抽芯铆钉，并且在通风管道零件安装的时分，这些零件都要通过镀锌处理才行。
2、 If it is a colorful coated steel plate ventilation duct, it should be adhered to that the inner wall is lubricated, and the coating should not be damaged during the processing of the ventilation duct. If the damaged area appears, it needs to be coated with epoxy resin on the surface. In the process of processing other ventilation ducts, anti-corrosion measures should be taken, and core pulling rivets cannot be used. Moreover, during the installation of ventilation duct parts, these parts must be galvanized.
三、通风管道加工的时分，不能在通风管道内部设置加固框或者加固筋，由于这样关于通风管道的质量会形成必定的影响。
3、 During the processing of ventilation ducts, reinforcement frames or ribs should not be installed inside the ducts, as this will have a certain impact on the quality of the ventilation ducts.
四、通风管道加工不能选用S型插条和C型直角插条的衔接方法，别的关于一些特别的通风管道来说，还不能选用按扣式的咬口。
4、 The connection method of S-shaped inserts and C-shaped right angle inserts cannot be used for the processing of ventilation ducts. For some special ventilation ducts, snap fit bites cannot be used.
五、通风管道制造结束之后，还要用清洗液进行清洗，只要到达清洗规范之后，才能够及时封口。
5、 After the manufacturing of the ventilation duct is completed, it needs to be cleaned with cleaning solution. Only after reaching the cleaning specifications can it be sealed in a timely manner.
