Background
The pipeline leakage monitoring system is used for monitoring a liquid (crude oil or other liquid) conveying pipeline for all days and seconds, and once the pipeline is perforated and leaked, the monitoring system can give an alarm in time through the information management system and perform engineering monitoring system management in a fixed-point positioning mode.
And because early engineering construction is not standard, operators do not strictly adhere to operation regulations or are unskilled, the welding technology is low, and the welding quality is poor. The pipeline joint door is not derusted and beveled according to the specification, so that the defects of air holes, slag inclusion, cracks, incomplete welding, undercut and the like are caused in welding. The welded junction is unqualified in corrosion prevention, the air tightness test of the pipeline is not strictly carried out, and the backfill quality does not meet the technical requirements. Although leakage does not occur when the liquid is just passed, the pipe network resists external interference and has poorer durability over time, and internal liquid leakage easily occurs after a period of operation. Because pipes are often in a concealed or harsh environment, such as underground pipes, management and monitoring of the pipes, and particularly monitoring of the leak, is not easy.
