What are the general common methods for pipeline pressure sealing and plugging?

Common methods for pressure-containing pipeline leak repair include: 1. Support method: For longer leaking pipelines, a support frame (such as specialized clamps or wraps) can be used around the leak area to maintain stability, followed by pressure-containing leak repair. 2. Twisting method: For minor leaks, the area around the leak can be slightly twisted to gradually reduce the leak size, ultimately achieving pressure-containing leak repair. 3. Plug method: For small leaks at the leak area, specialized materials (such as steel wire brushes, quick-drying adhesives, etc.) can be used to block the leak, stopping the leakage. 4. Cover method: For leaks that are not convenient for pressure-containing repair, specialized caps can be used to tightly seal the leak area, achieving pressure-containing leak repair. 5. Adhesive method: For small leak areas, adhesives (such as silicone, epoxy resins, etc.) can be used to seal the leak, achieving pressure-containing leak repair. These are the common methods for pressure-containing pipeline leak repair. Different methods are suitable for different leak situations, and choosing the right method can effectively improve the effectiveness of pressure-containing leak repair.
