In modern industrial production, the sealing technology with pressure is widely used, and its role and importance can not be ignored. Pressure plugging is a method of sealing pipes or equipment by applying pressure, which can effectively stop liquid or gas leakage and ensure the stability of the production process. This paper will discuss the principle, application field and development trend of pressure sealing technology, in order to understand the importance and prospect of this key industrial technology.

The principle of pressure sealing technology is mainly to use the sealing material to form an effective closure under pressure to prevent the leakage of fluid or gas. Common sealing materials include rubber, plastic, metal, etc., which have good elasticity and pressure resistance, and can withstand the effect of high pressure without cracking or deformation. When performing pressure sealing, it is first necessary to select the appropriate sealing material and size, and then install it on the pipe or equipment that needs to be blocked, and apply pressure to make it fully fit with the pipe wall or the surface of the equipment, so as to achieve an effective sealing effect.

Pressure plugging technology has a wide range of applications in industrial production, the most common of which is pipeline plugging. In petrochemical, electric power, water conservancy and other industries, pipeline system carries important transportation and flow tasks, once the leakage will lead to serious accidents and economic losses. Therefore, for these industries, pressure plugging technology is an important means to ensure production and stability. In addition, pressure plugging technology is also widely used in the field of equipment maintenance and testing, such as pressure vessels, pipeline valves and other equipment plugging and sealing testing, can effectively ensure the normal operation and maintenance of equipment.

With the continuous development and progress of industrial technology, pressure sealing technology is also constantly innovative and improved. The traditional sealing method with pressure mainly relies on manual operation, which has some problems such as low efficiency and poor performance. Modern pressure plugging equipment and technology have been gradually applied to industrial production, such as automatic pressure plugging system, remote monitoring pressure plugging technology, greatly improve the efficiency of plugging operations. In addition, with the continuous emergence of new materials and new processes, the application range of pressure sealing technology is also expanding, providing more options and possibilities for industrial production.

In the future, with the continuous development of industrial production and the improvement of automation level, pressure sealing technology will continue to play an important role. As the complexity and diversity of industrial equipment increases, the requirements for pressure sealing technology will become more stringent and refined. Therefore, engineers and technicians need to constantly learn and master the newer pressure plugging technology to cope with the increasingly complex industrial production environment. At the same time, the government and enterprises should also increase the research and development and promotion of pressure plugging technology, promote its wide application in industrial production, and contribute to the realization of efficient and sustainable industrial development.

In summary, as an important industrial sealing technology, pressure sealing technology plays an irreplaceable role in industrial production. Through continuous innovation and improvement, pressure sealing technology will provide more possibilities and guarantees for industrial production, and promote industrial production to a more efficient and automatic direction. It is hoped that more engineering and technical personnel and enterprises will invest in the research and application of sealing technology with pressure in the future, and jointly promote the sustainable development and progress of industrial production.
