Abstract
Description
Technical Field
[0001] The invention belongs to pipeline leakage performance detection technology, and in particular relates to a pipeline flange leakage detection device. Background Art
[0002] Leakage of industrial gases and liquids is an important problem in the operation of factories. When leakage occurs, it may endanger human safety and damage the surrounding environment, that is, the ecological balance, causing serious loss of life and property. Since the scope of industrial production equipment is often large, flange connections are generally used in places where it is often required to operate or disassemble. The sealing of the flange will deteriorate due to the indirect or direct influence of various conditions. If a certain method or device cannot be used to detect leakage of the installed flange, the sealing of the pipeline after it is put into operation cannot be guaranteed. If the flange connection leaks after the pipeline is in operation and then repaired, it will increase the workload and there will be certain safety hazards. At present, there is no specific device for detection after the pipeline flange is installed. The use of methods such as flaw detection is complicated and the work efficiency is low.
