AI Technical Summary
Existing technologies cannot accurately distinguish between leaks at flange interfaces and leaks on the outer wall of pipes, leading to misjudgments in sealing test results and making it impossible to achieve accurate testing of flange interface sealing.
A device for testing the sealing performance of petrochemical pipeline flanges was designed, including upper and lower sealing boxes and a sealing unit. A sealing annular space is formed by an arc-shaped plate and a telescopic cylinder to independently seal the flange and pipeline section. The sealing performance of the flange is determined by a pressure sensor.
It enables precise testing of flange interface sealing, avoids misjudgment of test results due to pipeline leakage, and ensures the reliability and accuracy of the test.
