Pressure plugging is a common custom process that can be used for leak remediation and plugging in systems such as pipes and containers. It is based on the principle of using an external force (usually pressure) to compensate or seal the leak point. In this article, I will introduce the process principles, materials and applications of pressure sealing in detail, and provide some relevant cases.

The principle of sealing with pressure is to use external pressure to compensate and fill the leakage point, so as to achieve the sealing effect. This process requires materials with high elasticity, chemical resistance and high temperature resistance to adapt to a variety of environmental and media conditions. Common sealing materials with pressure include rubber, polyurethane, silicone and so on.

Inspection and evaluation of the leak point must be carried out before applying the pressure sealing process. This includes determining the location, size, and conditions of the surrounding environment of the leak, as well as assessing the effects of pressure and temperature. Then select the appropriate compensation material and process parameters such as pressure and time. When the pressure plugging process is implemented, the compensation material needs to be accurately measured and mixed and applied to the leak point.

The application of pressure plugging is very wide. In the petroleum and chemical industries, it is commonly used for leak management and temporary closure of pipelines, storage tanks and equipment. For example, in the process of oil production, if a wellhead leak occurs, a pressure plug can quickly repair the leak and stop the oil and gas from escaping. In addition, in the factory and laboratory, the pressure plug can also be used for equipment leakage repair and plugging.

The following is a practical case that illustrates the application of the pressure sealing process. There was a leak in the tank of a petrochemical enterprise, resulting in the leakage of chemicals. To stop further leaks and reduce environmental pollution, engineers used a pressure plugging process. They first determined the location and size of the leak and assessed the effects of pressure and temperature. The compensation material suitable for the scene is then selected and applied to the leak point. By applying external pressure, the compensation material rapidly expands to fill the leak point and successfully seals the leak.

In summary, pressure plugging is a common custom process, suitable for pipeline, container and other systems leak repair and plugging. It is based on the principle that external pressure causes the compensating material to expand and fill the leak point. The selection of appropriate materials and process parameters is important, and leak points need to be inspected and evaluated. Pressure plugging has a wide range of applications in petroleum, chemical and other industrial fields, and can effectively repair leaks and prevent environmental pollution.
