Ventilation pipe construction Reinforcement can ensure Ventilation duct For the stability of internal static pressure in practical use, if the pipe wall presents 1% deflection, the ventilation pipe needs to be opened for reinforcement. In the process of reinforcing ventilation ducts, it is required to select corresponding reinforcement methods according to the pressure and size. The selection of reinforcement methods plays a decisive role in the service life of ventilation ducts. Generally, the following methods can be used to open the reinforcement.

One, tie rod reinforcement

In this process, it is required to use steel color, casing and other materials to open and strengthen, and it is required to open and strengthen under positive pressure below 500pa.

Second, structural reinforcement method

The method can be strengthened by opening light steel keel.

The third method is the cohesive reinforcement method

The material used during this period is also light steel keel, which is usually used in special pipeline reinforcement, mainly including 900 bend pipes, tee pipes and bulkhead pipes.

It can be seen from this that in the process of the reinforcement construction of the ventilation pipeline, the reinforcement needs to be opened according to the orientation of the pipeline, practical application and other aspects. In addition, anti sag reinforcement method can also be used. This method mainly opens and reinforces special pipes, which mainly includes circuitous pipes and warp pipes, so as to avoid displacement and sagging of ventilation pipes during practical use.
