Abstract

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. The detachable pipeline leakage sealing device is placed in a leakage position of a pipeline to realize leakage sealing of the pipeline, a sealing material layer can seal the pipeline leakage for the first time, meanwhile acompressing and fixing device can compress the sealing material layer to prevent a sealing material from loosening due to theexcessive pressure, at the same time, a rubber cover is arranged on the outer sideof the compressing and fixing device, and the rubber cover is tightly fitted on a shell body to be able to seal a secondary leakage again.The detachable pipeline leakage sealing device can replace the sealing material layer by removing the shell body and the rubber cover after the sealing material is saturated or corroded, so that recycling is realized; and the detachable pipeline leakage sealingdevice can also deal with different leakage situations of different pressure pipelines by adjusting compressing force provided by the compressing and fixing device, and the adjustment method is simple and convenient.

Description

technical field [0001] 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 technique [0002] Pipeline damage can be roughly divided into three categories: the first category is local small damage, such as leakage from small holes or small cracks. Such leaks are usually caused by localized corrosion or welding defects. The second type is local damage, which requires a protective device outside the steel pipe or replace the damaged part with a short pipe. This type of damage is the most common. The third category is that large-scale damage occurs on a relatively long pipe section, resulting in a significant reduction in the axial strength of the pipe. This situation requires the replacement of the damaged section with a long pipe section. [0003] The local damage of pipelines caused by corrosion and other factors is the most common form of pipe...
