Pressure plugging is a technique commonly used in pipeline plugging and repair work. It uses pressurized materials, such as tape, capsules, or inflatable bags, to plug holes or damaged parts of the pipe. This technology can be applied to different types of pipelines, including water pipes, gas pipelines, oil pipelines, etc.

The purpose of a pressure plug is to ensure the integrity of the pipeline. When a leak or damage occurs in the pipeline, the use of pressure sealing technology can quickly and effectively repair the problem, avoiding further losses and accidents.

Different types of sealing materials with pressure have different characteristics and application ranges. Here are some common sealing materials with pressure and their applications:

Pressure tape: Pressure tape is a kind of tape with strong adhesive force and pressure resistance. It can be used to plug small leaks or cracks and withstand a certain amount of pressure. Pressure tape is suitable for some smaller diameter pipes, such as domestic water pipes or small industrial pipes.

2. Inflatable bag: Inflatable bag is a sealing material that can be expanded by inflating. It is usually made of elastic material and can be adapted to different pipe shapes and sizes. The bag can be inflated in the pipe to create a sealed, isolated area that effectively stops the flow of liquid or gas. The inflatable bag is suitable for the blocking of medium and large pipes, such as industrial pipes or sewage treatment pipes.

3. Capsule sealer: Capsule sealer is a solid or liquid material, usually in the form of capsules. The capsule sealer can be released in the pipe to fill holes or damaged parts, creating a sealing layer. It is suitable for all kinds of pipes, including high temperature and high pressure pipes.

In addition to the above materials, there are a number of other pressure sealing techniques that can be applied to different types of pipes. For example, a plug kit is a set of equipment containing a variety of plug materials and tools that can be customized to the different needs of the pipeline. Plug kits are usually used by technicians to quickly plug pipes in an emergency.

It should be noted that the sealing technology with pressure needs to be carried out under the guidance of technical personnel. Incorrect plugging operations can lead to further damage or stability risks. Therefore, technical support and guidance should be sought when performing pressure plugging.

In summary, pressure plugging is a technique widely used in pipeline maintenance and repair. Different types of pipes can use different pressure sealing materials, such as pressure tape, inflatable bags, capsule sealers, etc. Pressure plugging technology can quickly and effectively repair leaks and damaged parts in the pipeline to ensure the integrity of the pipeline. However, it should be noted that the operation of pressure plugging technology should be cautious and carried out under the fingers of technicians.
