Shengli SL-2818 Leakage Detector for Buried Pipeline Coatings

【Function and Purpose】

    Without excavation, the leakage detector for buried pipeline coatings can find out the position, running direction, and depth of buried pipelines as well as the accurate position and the size of damaged points on coatings in a convenient and precise way.

    Shengli SL-2818 is the smallest and lightest leakage detector for underground pipeline coatings in China.

【Characteristics】

1. Planar design, operation through keyboard, to improve the reliability of outdoor servicing;

2. Small and light for convenient operation;

3. A brand new digital filtering technology is used;

4. Two detection modes available: maximum value and minimum value. Before under-voltage and power-off, the transmitter sends a reminder signal to the receiver automatically, data saved automatically at shutdown.

5. Pipe-to-earth resistance is measured by the device automatically, with modulated alarm signal output, enhancing the anti-interference of the device. The power output of the transmitter is adjusted automatically as the detection distance increases, and the transmitter power off automatically on completion of detection, saving electricity significantly.

6. Built-in power supply of the transmitter, the large-capacity lithium battery used, reducing weight significantly.

【Detection Principle and Methodology】

    Principles of pipe location and direction and depth detection: the transmitter sends a specified electrical signal to the underground pipeline, and determines its position, running direction and depth by detection of its magnetic field.

    Leakage detection principle: An electrical signal is sent to the underground pipeline by the transmitter.  A loop between the damaged point and the earth is formed and radiates to the ground, with the most intensive radiation right over the damaged points. Based on that, the damaged points on coatings are found.

    Leakage detection method: The coating leakage detector adopts “body capacitance method”, i.e., with human body as the induction element, and conducts detection along the pipeline. When the operator walks close to the leakage point, the leakage detector begins to react. When he is right above the leakage point, the volume in the loudspeaker is the highest and the displayed value is the largest. That’s how we can find the leakage point accurately.
