Shengli SL-5 Leakage Detector for Underground Pipeline Coatings

【Function and Purpose】

    It can find out the running direction and depth of underground pipelines as well as the accurate location of the leakage points on the coating in a convenient and precise way, which exempts the ground above the pipelines from “pains” of excavation. It’s a convenient and highly efficient detection device used by such departments as oil fields, chemical industry, oil transportation, gas transportation and water & electricity for construction quality and maintenance check on underground pipeline coatings.

【Characteristics】

1. Small, light and portable

2. Easy detection, convenient maintenance, automatic protection function available;

3. Low supply voltage, AC/DC available, high applicability

4. Large power and high efficiency of the transmitter;

5. Small detection error, strong capability of anti-interference;

6. Stable and reliable performance, well applicable to environments

【Primary Technical Parameters】

1.Leakage detection accuracy: 0.35mm2

2.Positional deviation: 30cm

3.Accuracy: 90%

4 Range of application: underground anti-corrosive metal pipelines of various diameters for oil, gas, water, etc.

A. Technical parameters of the transmitter:

Detecting Principles and Methodology】

    By sending a 1KHz electrical signal to underground pipelines, the detector determines the running direction and the depth of pipelines based on the principle that the received signal is the smallest (almost zero) when the probe is vertically tangent to the magnetic horizon.

    An AC signal source sent to the underground pipeline, in case the coating is corroded, the metal part at that area is short-circuited with the earth, and the loop is formed at the damaged point, which radiates the leakage point signal to the ground, with the strongest signal right above the damaged point. That’s the principle how we can find out the damaged point on the coating accurately.

    Leakage detection method: The leakage detector adopts “body capacitance method”, i.e., with human body as the induction element of the leakage detector. 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.
