通风管道如何进行加固？
How to reinforce the ventilation duct? What issues should be noted during the reinforcement process? The ventilation duct manufacturer will explain to you:
加固过程中，应根据管道压力巨细、管径巨细挑选相应的加固办法，加固办法的挑选，对通风管道的寿命有决定性的影响，一般情况下，可选用以下几种办法进行加固：
During the reinforcement process, corresponding reinforcement methods should be selected based on the pressure and diameter of the pipeline. The selection of reinforcement methods has a decisive impact on the service life of the ventilation pipeline. In general, the following methods can be used for reinforcement:
一、加固方法
1、 Reinforcement method
(1)加强抱合的办法
(1) Ways to strengthen hugging
所用材料也是轻钢龙骨，一般用于较特别的管道加固，主要有900弯管，三通管和闷头管等。
The material used is also a light steel keel, commonly used for special pipeline reinforcement, mainly including 900 bends, tees, and blind ends.
(2)拉线加固
(2) Stay wire reinforcement
该工艺要求选用钢色、套管等材料打开加固，正压加固要求在500 pa以下。
This process requires the use of steel color, casing and other materials for reinforcement, and the requirement for positive pressure reinforcement is below 500 pa.
(3)加强框架法
(3) Strengthening the framework approach
这种加固办法可用轻钢龙骨打开法进行加固。
This reinforcement method can be achieved by opening the light steel keel.
通风管道加固施工中，应根据通风管道方位粪池模具 路缘石模具 唐山通风管道 塑钢电缆挂钩 钢纤维 钢制拍门 植绒机 铜雕佛像、实践使用情况等方面打开加固工作。此外，还能够选用防下垂加固法，这种办法主要是对特别管材进行打开加固，其间主要包含迂回管材、经变管材等，以防止通风管道在实践使用中产生位移和下垂。
During the reinforcement construction of ventilation ducts, reinforcement work should be carried out based on the orientation and practical use of the ventilation ducts. In addition, anti sagging reinforcement method can also be used, which mainly involves opening and strengthening special pipes, including circuitous pipes, modified pipes, etc., to prevent displacement and sagging of ventilation pipes in practical use.
