Pressure plugging is a common pipe repair method used to repair or plug leaks, cracks, or other damage in a pipe. It has many features, which are described in detail below.

1. High efficiency: pressure sealing is a fast and effective pipeline repair method. Compared to traditional methods of pipe repair, it can be repaired without interrupting industrial production or services. This is because a pressure plug only needs to be constructed in the pipeline for a short period of time without stopping the operation of the entire pipeline system.

2. Wide applicability: pressure sealing is suitable for many types of pipelines, including oil, gas, chemical, water supply, drainage and other pipelines. It can repair pipes of different diameters and materials, such as steel pipes, cast iron pipes, plastic pipes, etc.

3. Flexibility: Pressure sealing can adapt to a variety of different pipeline damage conditions, including leaks, cracks, fractures, etc. It can repair damaged areas of various shapes and sizes, such as straight sections, curved sections, T-shaped pipes, etc.

4. Economy: Pressure sealing is a relatively economic pipeline repair method. It does not require large-scale materials and equipment, and can be repaired in a short time. Compared with traditional pipe replacement or welding repair, pressure sealing can greatly reduce repair costs.

5. Stability: Sealing with pressure is a relatively stable pipeline repair method. In the construction process, a series of safety measures can be taken, such as pressure monitoring, explosion-proof measures, etc., to ensure the safety of construction personnel and the surrounding environment.

6. Reversibility: pressure sealing is a reversible pipeline repair method. The repaired pipe can continue to be used and can be repaired or replaced again if needed. This reversibility makes pressure plugging a flexible solution.

7. Hygiene: Sealing with pressure is a sanitary pipeline repair method. It does not produce a lot of waste and pollutants, and has less impact on the environment.

8. Durability: After correct construction and reasonable maintenance, sealing with pressure can have a long service life. It can resist the influence of high pressure, high temperature, corrosion and other external environment to maintain the integrity and normal operation of the pipeline.

In short, pressure plugging is an efficient, widely applicable, economical, reversible, environmentally friendly and durable pipeline repair method. It plays an important role in various industrial and civil fields, providing reliable solutions for pipeline maintenance.
