Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pressure pipeline maintenance, in particular to a quick leak repair device for a pressure pipeline. Background Art
[0002] During the welding process of pressure pipelines, defects such as weld cracks, incomplete penetration, slag inclusions, porosity, and poor weld appearance may occur due to improper workmanship or operation. These defects reduce the cross-sectional area of the weld, lowering its load-bearing capacity, causing stress concentration and reducing the weld's fatigue strength, which can easily lead to pipeline perforation or brittle fracture. Leakage of media caused by perforations and brittle fractures not only causes production interruptions and wastes resources, but also poses significant safety hazards. If the pipeline medium is flammable, combustion and explosion may occur, resulting in major safety accidents.
[0003] Generally, pipeline leak repair is done by welding, which requires shutdown, pressure relief, and replacement. Achieving rapid leak repair without affecting production has always been a difficult problem in the industry, especially in some fire and explosion prevention units and departments that do not allow on-site hot welding. Some pipelines use clamp-type leak repair devices to repair pipelines, but general clamp-type leak repair devices use a single-layer steel plate structure, which is easy to deform and is only suitable for smaller-diameter non-pressure pipelines. For pressurized pipelines, especially large-diameter pipelines, general clamp-type leak repair devices are difficult to cope with and pose a great safety hazard.
[0004] Therefore, it is particularly important to design a quick leak repair device for pressure pipes to change the above technical defects and improve overall practicality. Utility Model Content
