Title: Application of pressure plugging technology in engineering design

In the field of engineering, pressure sealing technology is a widely used advanced technology, it plays an important role in various engineering projects. In this paper, the definition, principle, application field and design key points of pressure sealing technology are discussed in depth, aiming to help readers understand this technology more comprehensively and master its application methods.

### 1. Definition of plugging technology with pressure

Pressure plugging is a technique that applies pressure to fill a sealing material into a pipe or equipment to stop the flow of fluid or to stop a leak. This technology is widely used in engineering design, especially for the need to temporarily plug the pipeline or equipment, such as pipeline maintenance, testing, plugging leakage points and so on.

### 2. Principle of plugging technology with pressure

The principle of sealing technology with pressure mainly relies on the elastic deformation and recovery ability of the sealing material after deformation, as well as the applied pressure to fill it into the pipeline or equipment to achieve the purpose of effective sealing. Common sealing materials include rubber, plastic, metal, etc. Choosing the right sealing material is very important to ensure the sealing effect.

### 3. Application field of pressure plugging technology

Pressure plugging technology has a wide range of applications in various engineering projects, mainly including the following areas:

- Oil and gas engineering: In the process of oil and gas exploration, production, and transportation, it is often necessary to carry out pipeline sealing or leak prevention operations.

- Construction engineering: In construction, pressure sealing technology can be used to temporarily block pipelines to ensure the environmental health of the construction site.

- Sewage treatment engineering: In the maintenance and renovation of sewage treatment plants, pressure sealing technology can effectively reduce the pollution caused by discharged sewage to the environment.

### 4. Design points of pressure sealing technology

Design points are critical when applying pressure plugging technology, and here are some key points:

- Selection of sealing materials: Select the appropriate sealing materials according to the actual situation, considering the elasticity, pressure resistance, corrosion resistance and so on.

- Control of the plugging process: control the pressure, filling speed and filling amount during the plugging process to ensure the sealing effect and stability.

- Determine the sealing position: Determine the sealing position according to the specific conditions of the pipeline or equipment to avoid the leakage of the sealing material or the expected effect.

- Monitoring after plugging: After plugging is complete, monitoring is required to ensure that the plugging effect is good and avoid leakage due to improper plugging or material damage.

### Conclusion

As an important engineering technology, plugging with pressure is widely used and the effect is remarkable. Through the introduction of this article, I believe that readers have a deeper understanding of the pressure sealing technology, and can skillfully use this technology in practical engineering design to improve the efficiency and stability of engineering construction. It is hoped that this paper can provide some useful reference and inspiration for readers and promote the development and innovation of engineering technology.
