Pressure plugging is a common method of pipeline maintenance, the purpose of which is to stop the fluid leakage in the pipeline by applying pressure in the event of a pipeline failure. It is an economical and efficient method of pipe maintenance, suitable for all types of pipes and fluids.

The principle of pressure sealing is by placing a special tape or rubber gasket at the fault of the pipeline and applying enough pressure to maintain a tight seal. This method is more stable and reliable than traditional pipe maintenance methods because it can be repaired under pipe pressure and quickly resume normal operation of the pipe without stopping production.

Pressure plugging has the following main points:

1. Efficient and fast: Compared with traditional pipeline maintenance methods, pressure sealing has a faster maintenance speed, which can restore the normal operation of the pipeline in a short time, thereby reducing production downtime and losses.

2. Economical: Compared with traditional pipeline maintenance methods, the cost of materials and tools with pressure sealing is lower, which can reduce maintenance costs to a certain extent.

3. Stable and reliable: with pressure sealing, maintenance can be carried out under pipeline pressure, which can effectively reduce the stability risk in the maintenance process, and also ensure the normal operation of the pipeline.

4. Wide range of application: pressure plugging is suitable for various types of pipelines and fluids, whether in chemical, petroleum, gas, water treatment and other industries have been widely used.

In practical applications, sealing with pressure needs to pay attention to the following aspects:

1. Master the operation skills: with pressure sealing need to master the operation skills and operation process, to avoid the occurrence of operation errors and accidents.

2. Choose the right materials and tools: When selecting the materials and tools with pressure sealing, you need to choose the right materials and tools according to the actual situation to ensure that the maintenance effect meets the expectations.

3. Understand the nature of the pipeline and fluid: Before performing pressure plugging, it is necessary to understand the nature of the pipeline and fluid in order to choose the appropriate materials and tools, and take appropriate measures to ensure the maintenance effect.

4. Regular inspection and maintenance: Even if the maintenance is successful through pressure sealing, regular inspection and maintenance of the pipeline is needed to ensure lasting and stable maintenance effects.

In short, as an efficient, economical, stable and reliable pipeline maintenance method, pressure plugging has been widely used. In practical applications, we need to master the operation skills, choose the appropriate materials and tools, and take corresponding maintenance measures according to the nature of the pipeline and fluid to ensure that the maintenance effect is expected.
