Pressure plugging can refer to the technology of applying pressure and sealing measures in industrial production and civil construction in order to prevent the leakage or transition of gas, liquid or solid substances. This technology can be applied to various industries, such as petrochemical, energy, pharmaceutical, food processing, etc.

Pressure plugging technology is a very important process to ensure the reliability of equipment and pipelines in operation. The application of this technology can effectively prevent leakage and accidents, protect the safety of personnel and property stability.

The implementation of plugging technology with pressure requires advanced knowledge and advanced equipment, including plugging agents, plugging equipment, pressure sensors, etc. Before plugging with pressure, the leak source needs to be evaluated and analyzed to determine the appropriate plugging method and equipment.

Common plugging techniques with pressure include mechanical plugging, chemical plugging and hydraulic plugging. Mechanical plugging is through the use of mechanical tools, such as fixtures, cover plates, etc., to block the leak source. Chemical plugging is the use of chemical substances and leakage substances react to form a solid or colloidal plugging substance. Hydraulic plugging is done by using liquid pressure to inject the plugging material into the leak source to form a sealing layer.

Pressure plugging technology has many advantages. First, it can be plugged without downtime, reducing production downtime and production losses. Secondly, sealing with pressure can be carried out under high pressure environment and is suitable for a variety of complex working conditions. In addition, the pressure sealing technology can also reduce pollution and impact on the environment. However, there are some challenges and risks associated with pressure plugging technology. First of all, the selection and use of plugging agents need to consider their impact on equipment and pipelines to avoid secondary pollution and equipment damage. Secondly, the pressure sealing technology requires the knowledge and skills of the operator to ensure the correctness of the operation.

When selecting a pressure plugging technology, many factors need to be considered, such as the type and size of the leak source, the characteristics of the working environment, and the availability of plugging equipment and materials. At the same time, factors such as cost-effectiveness and sustainability need to be considered to ensure that the right pressure plugging technology is selected.

In summary, pressure sealing technology is an important technical means to ensure the reliability of equipment and pipelines in industrial production and construction. Its application can effectively prevent leakage and accidents, protect the life stability of personnel and property. However, the selection and implementation of pressure plugging technology needs to consider a variety of factors and requires the support of advanced knowledge and skills.
