The basic steps of the pressure plugging technique are as follows:

First, choose the right plugging equipment

According to the characteristics and size of the pipeline, choose the appropriate plugging equipment. Sealing equipment is generally made of rubber, nylon, PVC and other materials, with good sealing and corrosion resistance.

2. Preparation

Before sealing with pressure, a series of preparatory work needs to be carried out on the pipe, such as cleaning the inside of the pipe, removing the pipe valve, installing the support frame, etc.

Third, install plugging equipment

Put the selected sealing material into the pipeline through the pipe mouth, and then apply pressure through the pressure control system to make the sealing material fit the inner wall of the pipeline to form a seal.

Iv. Testing

After the installation is complete, perform a test to check the sealing effect. The test can be monitored by tools such as pressure gauges and thermometers.

In short, the pressure sealing technology can be used to seal the pipeline without stopping production. It is a technology to stop the leakage of the pressure pipeline, also known as the pressure sealing technology. It is the introduction of a certain pressure in the pipeline so that it can resist the pressure inside the pipeline when it is blocked, and maintain the integrity of the pipeline. This technology can be widely used in various pipeline systems such as oil and gas pipelines, chemical pipelines, water treatment pipelines, and water supply pipelines to ensure the stable operation of pipelines. In this article, we will describe in detail the application and benefits of pressure plugging technology.

First, the application of pressure plugging

1. Oil and gas pipelines

In oil and gas pipelines, pressure sealing technology can be used to detect the presence of leaks or damage in the pipeline. Oil and gas pipeline is a high-risk pipeline, once the leak may cause explosion or fire and other serious accidents. Pressure plugging technology can introduce a certain pressure in the pipeline, detect the leak or damage in the pipeline, and determine the leak location and leakage amount for timely maintenance.

2. Chemical pipeline

In the chemical pipeline, pressure sealing technology can be used to protect the stable operation of the pipeline. Chemical pipeline is high temperature and high pressure pipeline, once the leak may cause serious chemical reaction and toxic gas leakage. Pressure plugging technology can introduce a certain pressure in the pipeline to maintain the integrity of the pipeline to prevent pipeline leakage and explosion accidents.

3. Water treatment pipe

In water treatment pipelines, pressure sealing technology can be used to detect the presence of leaks or damage in the pipeline. Water treatment pipeline is designed to ensure the stable operation of water, once leaking may cause water pollution and waste of water resources. Pressure plugging technology can introduce a certain pressure in the pipeline, detect the leak or damage in the pipeline, and determine the leak location and leakage amount for timely maintenance.

4. Water supply pipe

In the water supply pipeline, pressure sealing technology can be used to protect the stable operation of the pipeline. Water supply pipeline is a pipeline designed to provide clean drinking water, and once leaked, it may cause water pollution and waste of water resources. Pressure plugging technology can introduce a certain pressure in the pipeline to maintain the integrity of the pipeline to prevent pipeline leakage and water pollution accidents.

Second, the advantages of pressure sealing

High efficiency

Pressure plugging is an emergency repair method used in pipelines or containers, its main role is to form an isolated area in the pipeline or container for repair, replacement or cleaning work. This method is to inject a specific sealing material into the pipe or container to form a sealed sealing area, and maintain a certain pressure in the process to ensure the sealing effect.

Pressure plugging is typically used in the following situations:

1. Leakage or failure occurs in the pipeline or container

When there is a leak or failure in a pipe or container, a pressure plug can quickly solve the problem. By injecting the sealing material into the pipe or container, a tight sealing area can be created to stop leaks or further damage. At the same time, maintaining a certain pressure can also ensure the sealing effect.

2. Pipes or containers need to be repaired, replaced or cleaned

When performing pipe or container repair, replacement or cleaning work, pressure sealing can help workers more stable and convenient operation. By injecting the sealing material into the pipe or container, an isolated area can be formed to avoid interference from other substances. At the same time, maintaining a certain pressure can also ensure the stability of the working area.

3. Inspection or testing of pipes or containers is required

Pressure plugging can also be convenient when conducting inspection or test work on pipelines or containers. By injecting the sealing material into the pipe or container, an isolated area can be formed to avoid the influence of other substances, thus ensuring the accuracy of the test results. At the same time, maintaining a certain pressure can also ensure the stability of the test process.

The specific steps of the pressure sealing method are as follows:

1. First, determine the location and size of the pipe or container that needs to be blocked, and the parts that need to be repaired, replaced or cleaned.

2. Prepare sealing materials and plugging devices, including sealing belts, air sources, and pressure gauges.

3. Insert the sealing tape into the pipe or container and ensure that the sealing material completely fills the inside of the pipe or container to form a sealed sealing area.

4. While injecting the sealing material, gradually increase the pressure of the air source to maintain a certain pressure and ensure the sealing effect.

5. After the sealing material is completely hardened, check whether the sealing area is completely sealed to ensure stability.

In short, sealing with pressure is a very practical emergency maintenance method, which can help to quickly and stably deal with problems in pipelines or containers, improving work efficiency and stability. At the same time, the correct use of pressure sealing method also requires a certain amount of technical and operational knowledge, be sure to operate under the guidance of technical personnel.
