通风管道生产线在很多情况下很容易出现松动一味的情况，这个时候我们就需要对通风管道进行加固。
Ventilation pipeline production line is prone to loose blindly in many cases, at this time we need to reinforce the ventilation pipeline.
,我们要先使用扒形装订针来固定管道的搭接口，装订针的间距好是50mm。装订时，装订针应与接缝略呈角度。装订针仅用于有盖舌的搭接口固定，若无盖舌，或平接口时，应用胶带接片进行固定。然后再使用密封胶带来进一步固定，一般来说，消音通风管使用的密封胶带有热敏胶带、压敏胶带两种。胶带大为300mm，每边少1个。
Firstly, we need to fix the lap joint of the pipeline by using the pickup binding needle. The best distance of the binding needle is 50mm. When binding, the binding needle should be slightly angled with the seam. Binding needle is only used for fixing lap joint with cover tongue. If there is no cover tongue or flat joint, tape joint is used for fixing. Then use sealant tape to further fix. Generally speaking, energy-saving silencing ventilation duct uses two kinds of sealant tape: heat-sensitive tape and pressure-sensitive tape. The maximum tape is 300 mm, at least one on each side.
当通风管道系统内部的静压负载使玻纤通风管道管道壁出现1%的挠度时，就需要对通风管道进行加固。通常消音通风管道系统管道可采用以下方法来进行加固：
When the static pressure load inside the ventilation duct system causes 1% deflection of the wall of the glass fiber ventilation duct, it is necessary to reinforce the ventilation duct. Usually energy-saving muffling ventilation pipeline system can be strengthened by the following methods:
a.拉杆加固法，它是采用钢彩、套管加固，通常使用在500Pa以下的正压加固。
A. Tie rod reinforcement method, which uses steel color, casing reinforcement, usually used under 500 Pa barotropic reinforcement.
b.框架加固法，即采用轻钢龙骨加固。
B. Frame reinforcement method, i.e. light steel keel reinforcement.
c.抱合加固法，即采用轻钢龙骨加固，使用在拉杆加固和框架加固无法应用的某些特殊管道上，如900弯管、三通管、闷头管等。
C. Enclosure reinforcement method, i.e. light steel keel reinforcement, is used in some special pipes which can not be applied in tie rod reinforcement and frame reinforcement, such as 900 elbows, tee pipes, stuffy pipes, etc.
d.防下垂加固法，它用于特殊管道的加固，如变经管道加固和迂回管道加固。
D. Drop-proof reinforcement method, which is used to reinforce special pipelines, such as pipeline reinforcement and circuitous pipeline reinforcement.
