A structure with a pressure plug is a technique commonly used in the engineering field to solve problems such as leaks or oil leaks in systems such as pipelines, containers, and boreholes. The characteristics of the structure include three key elements, pressure and plugging, which I will introduce in detail below.

First, it means that a leak or damaged part of a system such as a pipeline or borehole is expanded by a special device so that it can be subsequently sealed with pressure. The expansion method can be mechanical expansion, chemical expansion or thermal expansion and cold contraction, in order to make the size of the hole suitable for subsequent sealing operation. The process of overwriting requires precise control and manipulation to ensure that the vulnerability is fully extended without causing further damage.

Secondly, pressure is another important feature of pressure sealing structures. After completion, it is necessary to apply a certain pressure to ensure that the sealing material can fully fill the hole and achieve the sealing effect. This operation with pressure can be achieved by hydraulic, pneumatic or mechanical forces, and the pressure needs to be monitored and adjusted in real time to ensure that the sealing effect meets the requirements.

Finally, plugging is the ultimate goal of sealing structures with pressure. In the process of pressure, it is necessary to select the appropriate sealing material to fill the hole, and ensure that it has high pressure resistance, corrosion resistance, temperature change and other characteristics. Common sealing materials include polymer resin, cement slurry, adhesives, etc. Different application scenarios and requirements may require different sealing materials. After plugging is complete, tightness testing and quality inspection are required to ensure the reliability of the system.

To sum up, the characteristics of the sealing structure with pressure include three aspects, pressure and sealing, each aspect requires fine operation and strict control. This structure has a wide range of applications in the field of engineering, can effectively solve the pipeline leakage, well oil leakage and other problems, to ensure the stable operation of the system and environmental protection. I hope that the above introduction can help you better understand the characteristics and applications of pressure sealing structures.
