    Pipeline Leak Detection

    Overview Knowledge Standards Terms
    Pipeline leak detection identifies leakage points through pressure changes, acoustic wave transmission, or tracer gas detection. It is used in water supply and oil and gas transportation to locate damage positions, preventing medium loss and environmental hazards.
    Selection
    Select pressure detection or acoustic methods based on media characteristics. Hydrogen tracing is suitable for gas pipelines. Choose sensor sensitivity considering pipe wall thickness, and use positioning instruments for underground pipelines. Equipment in humid environments requires waterproof ratings.

    Negative pressure method leak detector for testing vacuum packaging seal integrity
    The negative pressure leak detector evaluates the seal integrity of vacuum packaging by simulating a pressure differential environment. The instrument places the sample in a testing chamber and creates a vacuum to form negative pressure. If there is a leak, air or liquid will seep into the packaging, and the result is determined by observing pressure changes or the presence of bubbles.
