Pipeline Spark Leak Detector

The pipeline spark leak detector operates on the principle of high-voltage discharge. When the probe moves over the coating surface, if there are leaks in the coating, the high voltage will break down the air, generating visible sparks. It is used to detect the continuity of anti-corrosion coatings on metal pipelines, locate defects such as pinholes and cracks, and ensure the effectiveness of pipeline corrosion protection.
Selection
When selecting, consider matching the detection voltage range with the coating thickness, typically categorized into low-voltage, medium-voltage, and high-voltage types. Choose the probe type—brush or ring—based on the shape of the pipeline. Ensure the device includes safety features such as audible and visual alarms and automatic power-off. Portable devices are suitable for fieldwork, while fixed types are ideal for production lines.
