【Scope of Application】
Shengli SL-580B
multi-purpose full-frequency pipeline detector is the ideal equipment specially
detecting various kinds of pipelines for oil (gas) transportation, water
supply, drainage, gas, heat, and industry, etc. and various cables for
electricity and telecommunication, etc. used by such underground pipeline
design organizations as professional pipeline detection, pipeline management
and maintenance, municipal administration planning and construction , power
supply, building and construction. It’s also the optimum replacement for
traditional underground pipeline detectors.
【Characteristics】
1. DSP processor
used to provide a fast calculation speed and a high accuracy;
2. The orientation
function to indicate the pipeline running direction, making location faster;
3. Adoption of the
10W broadband transmitter, applicable to various environments;
4. With the Lithium
battery supplying power for both the receiver and the transmitter, being
environmentally friendly;
5. The display is
backlighted, applicable to night emergency rescue;
6. Indication with
left and right arrows, able to rapidly locate the pipeline;
7. Front and back
arrows and dB values to indicate the location of the damaged points on coatings
during detection of the damaged points on coatings.
【Working Principles】
Pipeline location
and depth investigation principle:
Shengli SL-580B
multi-purpose full-frequency pipeline detector detects underground pipelines
electromagnetically, which applies signals to metal pipelines through the
transmitter, generates pipeline current in metal pipelines and secondary
magnetic field around pipelines, and measures the secondary magnetic field of
pipelines on ground through the receiver, in order to accurately determine the
location, buried depth, running direction, route, and signal current intensity
of pipelines.
Leakage testing on
anti-corrosive coatings principles
An electrical
signal is sent to the underground metal pipeline through the transmitter. In case
damaged points exist on the underground pipeline coating, they are
short-circuited with the earth, generating creepage current radiating all around,
with the most intensive radiation above the damaged points. Based on that, the
damaged points on coatings are found.
