Technical Field
The invention relates to the technical field of oil and gas storage and transportation pipeline equipment, in particular to a detachable pipeline leakage sealing device.
Background
The destruction of pipes can be broadly divided into three categories: the first type is a small local failure, such as a small hole or a small crack leak. Such leaks are often caused by localized corrosion or weld defects. The second type is localized destruction, requiring either protective devices on the outside of the steel pipe or short pipe replacement of the destroyed part. Such damage is most common. The third category is the large-scale damage that occurs on relatively long pipe sections, resulting in a significant reduction in the axial strength of the pipe. This situation requires the replacement of the damaged portion with a long tube segment.
Local damage to a pipeline due to corrosion and the like is the most common form of pipeline damage. Local replacement and repair are often performed in the face of such damage, but such methods take a long time and effort, and thus remediation by external protection is the most economical and rapid repair method.
