通風管道生產線在很多情況下很容易出現松動一味的情況，這個時候我們就需要對通風管道進行加固。
　　Ventilation pipeline production line is prone to loose blindly in many cases, at this time we need to reinforce the ventilation pipeline.
　　首先,我們要先使用扒形裝訂針來固定管道的搭接口，裝訂針的間距好是50mm。裝訂時，裝訂針應與接縫略呈角度。裝訂針僅用于有蓋舌的搭接口固定，若無蓋舌，或平接口時，應用膠帶接片進行固定。然后再使用密封膠帶來進一步固定，一般來說，節能消音通風管使用的密封膠帶有熱敏膠帶、壓敏膠帶兩種。膠帶大為300mm，每邊至少1個。
　　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.
　　當通風管道系統內部的靜壓負載使玻纖通風管道管道壁出現1%的撓度時，就需要對通風管道進行加固。通常節能消音通風管道系統管道可采用以下方法來進行加固：
　　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.拉桿加固法，它是采用鋼彩、套管加固，通常使用在500Pa以下的正壓加固。
　　A. Tie rod reinforcement method, which uses steel color, casing reinforcement, usually used under 500 Pa barotropic reinforcement.
　　b.框架加固法，即采用輕鋼龍骨加固。
　　B. Frame reinforcement method, i.e. light steel keel reinforcement.
　　c.抱合加固法，即采用輕鋼龍骨加固，使用在拉桿加固和框架加固無法應用的某些特殊管道上，如900彎管、三通管、悶頭管等。
　　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，如變經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.
