In modern engineering construction, the installation of pressure plugging is a very important engineering requirement. The purpose of this work is to ensure that the pipeline system can operate normally during use, prevent leakage and damage, and ensure the reliability of the project. This paper will introduce the engineering requirements of installation with pressure plugging in detail, including its definition, function, construction steps, precautions, etc., to help readers better understand this important engineering requirements.

I. Definition

Sealing with pressure means that after the installation of the pipeline system, the pipeline system is closed by applying a certain pressure to detect whether there are loopholes or defects in the pipeline system, and the pipeline system can also be debugging and trial operation. Sealing with pressure is an important link in the construction of pipeline system, and its quality directly affects the reliability of the whole project.

Second, the role

1. Check whether the pipeline system has loopholes or defects. With pressure sealing, the piping system can be fully inspected, potential problems can be found and repaired in time, and the integrity and tightness of the piping system can be ensured.

2. Commissioning and trial operation of pipeline system. In the process of sealing with pressure, the actual operation can be simulated, and the pipeline system can be debugged and trial run to ensure its normal operation and stability.

3. Improve the construction quality. Sealing with pressure is an important link in the construction of pipeline system, ensuring the sealing and stability of pipeline system can guarantee the reliability of the project and improve the construction quality of the project.

Third, construction steps

1. Preparations: Determine the location and method of sealing with pressure, prepare the required sealing materials and equipment, and ensure the cleanliness of the construction site.

2. Preparations for sealing: Clean the pipeline system and ensure that there is no debris inside the pipeline. Install plugging devices, such as plugging heads and plates.

3. Pressure test: Apply a certain pressure to test, observe whether there is leakage or abnormal situation in the pipeline system, and deal with the problem in time.

4. Sealing completion: After confirming that there are no leakage points in the pipeline system, seal the pipeline system to ensure that it is sealed properly.

5. Test and acceptance: Test and acceptance of the pipeline system with pressure sealing to ensure that the project quality meets the requirements.

4. Precautions

1. Construction personnel must have relevant technology and experience, and operate in strict accordance with construction specifications and requirements.

2. Pay attention to safety during the construction process to ensure the cleanliness of the construction site and avoid accidents.

3. Check and verify the plugging equipment and materials to ensure that their quality and performance meet the requirements.

4. In the process of sealing with pressure, problems should be discovered and dealt with in time to ensure the reliability of the pipeline system.

5. After the completion of construction, the pipeline system should be comprehensively tested and accepted to ensure that the project quality meets the requirements.

Summary: The installation of pressure plugging is a very important engineering requirement, its role is to detect whether there are loopholes or defects in the pipeline system, debug and trial run the pipeline system, and improve the construction quality of the project. In the construction process, the construction personnel must have the relevant technology and experience, and operate in strict accordance with the construction specifications and requirements to ensure the reliability of the pipeline system. It is hoped that this paper can help readers better understand the engineering requirements of installation with pressure plugging, and improve the construction quality and efficiency of the project.
