Abstract

With the increasing severity of leakage issues at chemical pipeline flange connections, research on leakage detection technologies has become increasingly crucial. This paper compares and analyzes various commonly used detection methods, including ultrasonic testing, infrared thermal imaging, gas detection, and acoustic detection, evaluating their application effectiveness and limitations under different operating conditions. By comparing the sensitivity, detection accuracy, and applicability of each method, this study reveals the advantages and disadvantages of different approaches in chemical pipeline flange leakage detection, as well as their suitable scenarios, providing practical references for engineering applications. The research demonstrates that selecting appropriate detection methods can effectively enhance the efficiency and accuracy of leakage identification, thereby reducing safety hazards.
