Pressure plugging is a common engineering technology, which is widely used in various fields, including construction, petrochemical, water treatment, health care and so on. Its production history can be traced back to decades or even hundreds of years ago, after a long period of improvement, today has become a mature and reliable technology.

The purpose of a pressure plug is to apply pressure in the pipe or equipment so that it can withstand specific working conditions while ensuring the tightness of the working area. This technique is commonly used in processes such as pipeline installation, maintenance and testing. During construction or maintenance, a pressure plug can help engineers reduce downtime, increase productivity, and ensure stability.

The production process with pressure sealing needs to go through the following steps:

Design and planning: Based on actual engineering requirements, engineers need to design and plan based on factors such as the size, material and working conditions of the pipe or equipment. These

2. Material selection: According to the design requirements, choose the appropriate material to make the plugging device. Commonly used materials include rubber, metal and plastic.

3. Make plugging device: Make plugging device according to design requirements and selected materials. Typically, these devices include components such as plugging heads, sealing rings, pipe clamps, etc. Factors such as strength, tightness and pressure resistance of the device need to be considered in the production process.

4. Installation and testing: Install the plugging device on the pipeline or equipment that needs to be blocked, and apply the required pressure. After applying pressure, it is necessary to perform a sealing test to ensure that the plugging device can withstand the pressure under working conditions and maintain a good seal.

With the development of science and technology and the progress of engineering technology, there have been some innovations in the production process of pressure sealing technology. For example, advanced technologies such as computer design (CAD) and 3D printing can now be used to produce high production efficiency and degree of sealing. In addition, the application of new materials also brings more options for the production of plugging devices.

In short, as a heavy engineering technology, pressure plugging has become an indispensable part of all walks of life after years of development and improvement. It plays an important role in the process of engineering construction and maintenance, improving work efficiency and stability. With the continuous progress of technology, we believe that pressure sealing technology will continue to develop in the future and bring new breakthroughs to more engineering fields.
