Pressure plugging is a common pipe maintenance and repair technique used to repair leaking or broken parts of a pipe. It applies pressure to the surface of the pipe by plugging material holes or cracks to restore the integrity and function of the pipe. It is true that some noise is generated when a pressure plug is carried out. Below I will explain in detail the causes of the noise generated by the pressure plug and how to reduce the noise.

1. Causes of noise caused by pressure sealing:

The noise generated in the process of sealing with pressure mainly comes from the following aspects:

- Pressure mechanical equipment: In the process of sealing with pressure, usually use pressure mechanical equipment, such as pneumatic screw machine, hydraulic pump, etc., these equipment will produce noise during the working process.

- Vibration and collision: The injection and compaction of the sealing material can cause vibration and collision inside the pipe, resulting in noise.

- Gas and liquid flow: During the plugging process, gas and liquid will flow through the inside of the pipe, resulting in flow noise.

2. Methods to reduce noise generated by pressure plugging:

Although there is a certain amount of noise generated during the pressure plugging process, there are a number of measures we can take to reduce the impact of noise:

- Use less noisy equipment: Choose low noise pressure mechanical equipment, such as using low noise pneumatic screw machine or hydraulic pump.

- Use of sound insulation: When performing a pressure closure job, sound insulation facilities such as sound panels or enclosures can be placed around to reduce noise transmission.

- Control flow rate: By controlling the injection speed of the sealing material, reducing the flow speed of the gas and liquid, the flow noise can be reduced.

- Use of sound-absorbing materials: On the surrounding walls or floors of the sealing job site, sound-absorbing materials can be used to cover them to absorb noise and reduce reflection and transmission.

- Work at the right time: try to choose a time period with fewer people or low ambient noise to carry out the pressure closure operation to reduce the interference to the surrounding environment.

In SUMMARY:

Pressure plugging plays an important role in pipeline maintenance and repair, but at the same time it will produce a certain amount of noise. To reduce the impact of noise, we can choose to use less noisy equipment, install soundproofing, control flow rates, use sound-absorbing materials, and work at the right time. By taking these measures, the noise generated by the operation with pressure closure can be reduced to a greater extent, and the surrounding environment and personnel comfort can be protected.
