Abstract

The invention discloses a sealing device and method for pipeline emergency maintenance. The device comprises: a left upper half flange, a left lower half flange, a right upper half flange, a right lower half flange, a sealing member, and several bolts; The flange and the lower left half flange are connected by bolts to form the left flange; the upper right half flange and the lower right half flange are connected by bolts to form the right flange; The lower left half flange, the upper right half flange and the lower right half flange are connected by bolts to form a vertical compression load on the seal to fasten the seal; the upper left half flange and the upper right half flange, and the lower left half flange and The lower right half flange is connected by bolts to form a horizontal compression load on the seal to fasten the seal; this device solves the technical problems of pipeline prevention and emergency maintenance in narrow spaces, high temperature and high pressure harsh environments, and provides maintenance for pipeline components. Necessary equipment and methods.

Description

technical field [0001] The invention relates to the field of pipeline maintenance, in particular to a sealing device and method for pipeline emergency maintenance. Background technique [0002] Pressure-bearing pipeline components have a high failure rate in long-term service under harsh working conditions of high temperature, high pressure, and radiation. Once the pipeline leaks, there is a great risk to the safe operation of the equipment. The maintenance of such pipelines generally has the characteristics of long cycle and high cost. [0003] According to the current published literature, most of the pipeline repairs are for conventional pipelines, using conventional methods, such as direct welding, which will be limited by the thickness of the pipeline wall, the preparation of welding tools and materials, the operating space, and the skill level of the welder; Adding caps or valves at the end of the pipe is more complicated to implement and requires some damage to the o...
