AI Technical Summary
During operation, gas pipelines are prone to corrosion at flange connections, which can lead to leaks and pose a safety hazard.
The upper and lower protective sleeves are made of aluminum alloy and are mechanically reinforced by a worm gear and worm mechanism. They are also equipped with pressure sensors and an alarm system to monitor leakage at the flange connection in real time.
It effectively prevents flange connections from loosening, detects leaks in a timely manner and issues alarms, thereby improving the safety and reliability of gas pipeline operation.
