Description

Technical Field

[0001] The utility model relates to the technical field of flange leakage repairing devices, in particular to a flange leakage repairing device. Background Art

[0002] Pipeline is the most basic unit for transporting gas. Pipelines are usually connected by flanges, and gaskets are set between the flanges. In the process of gas pipeline transportation, with the increase of service life, and some gases have certain corrosiveness and other factors, the seals at the flange connection of the pipeline will age or other reasons will cause gas leakage. If not handled in time, the leakage may become more serious and may even cause safety accidents.

[0003] In actual production, it is often not possible to stop gas transmission immediately to repair gas leakage, because gas pipeline transportation is a systematic project. Stopping gas transmission requires all equipment to stop running, which has a large scope, high cost, and poor operability, seriously affecting normal production operations. Therefore, it is urgent to propose a device for repairing flange leaks without stopping gas transmission. Utility Model Content
