| 发明名称 | Pipeline leak sealing system and method | ||
| 摘要 | A method for sealing a leak in a pipeline used to transport fluid includes positioning a sealing device within the pipeline, moving the sealing device through the pipeline to a leak location, and internally generating an inflation pressure to inflate the sealing device to substantially cover a leak opening and limit release of the fluid from the pipeline. | ||

| 主权项 | 1. A method for sealing a leak in a pipeline used to transport fluid, the method comprising: positioning a sealing device within the pipeline, the sealing device comprising an inflatable bag and an adhesive; moving the sealing device through the pipeline to a leak location; and limiting the release of fluid from the pipeline at the leak location by: internally generating an inflation pressure to inflate the inflatable bag to substantially cover a leak opening at the leak location; andadhering the sealing device to an interior wall of the pipeline at the leak location using the adhesive. | ||
