Piping is a common piping process that is often used to expand an existing piping system to meet increased demand. Pressure plugging is an important technology in the expansion pipeline engineering, which is widely used in various pipeline systems.

Pressure sealing is a common pipeline sealing technology, which is widely used in various pipeline systems. In pipeline engineering, pressure plugging is mainly used in the following situations:

1. Sealing of pipe joints: In pipeline engineering, it is usually necessary to connect new pipe joints to the existing pipe system. These joints must be effectively sealed to prevent leakage. Pressure sealing technology can apply pressure in the pipeline system to seal the pipeline, so as to ensure the stable operation of the pipeline system.

2. Pipeline testing: In pipeline engineering, it is necessary to test the new pipeline system to ensure its stable operation. Pressure plugging technology enables piping systems to be tested under high pressure to detect leaks and other faults in the piping system.

3. Pipeline maintenance: When there is a failure in the pipeline system, maintenance is needed. Pressure plugging technology can stop fluid leakage during maintenance and enable maintenance personnel to carry out maintenance work steadily.

The realization of pressure sealing technology requires the use of special sealing equipment, such as pressure sealers and gaskets. These devices can apply high forces in the piping system, thus achieving an effective sealing of the piping system. When pipeline work is required, pressure plugging technology is often used to seal pipe joints, test pipe systems, and perform maintenance work.

When using pressure plugging technology, the following points need to be noted:

Stability: In the construction of pressure sealing technology must pay attention to the stability of the construction personnel. High pressure can cause harm to the construction personnel, so it is necessary to take the necessary stabilization measures and ensure that the construction personnel have the necessary knowledge and experience.

2. Equipment selection: When selecting the sealing equipment with pressure, it is necessary to select the appropriate equipment according to the characteristics and requirements of the pipeline system. At the same time, it is necessary to ensure the quality and reliability of the equipment to ensure the stable operation of the pipeline system.

3. Construction operation: In the construction of pressure sealing technology, it is necessary to operate in accordance with relevant regulations and operational requirements to ensure that the sealing equipment can effectively seal the pipeline system.

In short, pressure sealing technology is an indispensable technology in pipeline engineering. After mastering the operation points and precautions of the technology, the stable operation of the pipeline system can be ensured.
