Pressure plugging is a common quality improvement method used to address leakage, failure, or other quality issues in a product or system. In this method, vulnerabilities are detected and repaired by applying pressure and plugging, thereby improving the quality and reliability of the product. This paper will introduce the working principle, application field and implementation process of sealing with pressure in depth.

The principle of sealing with pressure is to use pressure to test the sealing performance of a product or system. During testing, a medium, such as a liquid or gas, is injected into the product or system through a pressure source, and pressure changes are monitored by instruments such as pressure gauges. If the pressure is always stable, it indicates that the product or system has good sealing performance; If the pressure drops, it indicates a leak or other quality problem.

Pressure plugging is widely used in many fields, including industrial manufacturing, petrochemical, nuclear energy and so on. In the field of industrial manufacturing, pressure plugs can be used to detect and repair leaks in pipes, containers, valves and other equipment. In the petrochemical industry, pressure plug can be used to test and repair leaks in oil Wells, pipelines, storage tanks and other facilities. In the field of nuclear energy, pressure plugging is an important means to ensure the stable operation of nuclear facilities.

The process of implementing a pressure plug usually consists of the following steps. First, identify the equipment or system that needs to be tested and repaired, and select the appropriate sealing material and sealing method. Secondly, prepare the pressure source and related instruments and equipment to ensure their normal operation and accurate measurement. Then, the medium is injected into the device or system, and the pressure is gradually increased to monitor the pressure change. If a drop in pressure is found, the leak needs to be located and repaired. Repair can take different methods, including replacing seals, plugging holes, repairing damaged parts, etc. Finally, re-perform the pressure test to ensure that the repaired equipment or system meets the requirements.

The advantage of the sealing method with pressure is that it can test and repair the equipment or system under actual working conditions, and judge its sealing performance more accurately. At the same time, it also has certain limitations, such as the inability to detect small leaks, and requires a certain amount of advanced knowledge and experience to implement correctly.

In summary, pressure plugging is an effective quality improvement method that can be used to detect and repair leaks in products or systems. In the implementation process, it is necessary to pay attention to the selection of appropriate sealing methods and materials, and strictly follow the operating procedures. By plugging with pressure, the quality and reliability of the product can be improved to ensure that the equipment or system operates under normal operating conditions.
