Shandong Kedian underground pipeline leak detector FJ-10 buried pipeline anti-corrosion coating leak detector

The FJ-10 buried pipeline anti-corrosion layer detection leak detector is a new generation of digital, intelligent, and multifunctional buried pipeline anti-corrosion layer detection leak detector. This instrument can conveniently and accurately locate the position, direction, depth, anti-corrosion layer damage points and sizes, and insulation resistance of buried pipelines without excavating the covering soil. This instrument is currently an advanced instrument in China for detecting the condition of the anti-corrosion coating of buried pipelines on the ground, the corrosion status of the pipeline body, and locating the corrosion points of the pipeline body. It is a detection instrument used by departments such as oil fields, chemical industry, oil and gas transportation, water and electricity, and heating to ensure the safe operation of pipelines, improve unit economic benefits, detect pipeline corrosion points in advance, and prevent corrosion leakage accidents.

Characteristics of the instrument
1. Adopting a flat design and keyboard operation, one click multi use.
2. Without the need for additional wiring, simply press the measurement button to automatically measure parameters such as transmission power, transmission voltage, transmission current, and grounding resistance.
3. The signal strength of the entire detection process is normalized by the internal circuit to ensure comparability of the leakage point size and insulation resistance value of the anti-corrosion layer in each measurement section.
4. Adopting voltage controlled vibration frequency technology to make the signal strength response of pipe position and leakage point clearer.
5. Sound system, indication, analog bar cursor, display signal strength more intuitively.
6. Easy to operate, simple to use, easy to learn and understand.
7. Small size, light weight, easy to carry, and more suitable for field testing.
8. When the instrument voltage is insufficient, it automatically shuts down, and when it shuts down, it automatically cuts off the internal power supply, which has a significant energy-saving effect.
[Function and Purpose]
Function:
This instrument can easily and accurately locate the position, direction, depth, anti-corrosion layer damage points and sizes, and insulation resistance of buried pipelines without excavating the covering soil.
Purpose:
Conduct pipeline acceptance according to SYJN4029-88 and GJJ33089 standards;
Conduct final acceptance of newly laid pipelines;
Regularly inspect pipelines according to safety regulations to determine the effectiveness of cathodic protection;
★ Locate the branches on the supervisory line;
★ Conduct inspections on old pipelines to determine the condition of their anti-corrosion coatings;
Before excavating and breaking soil in the construction section, inspect the distribution of underground pipelines to prevent damage to underground oil, gas, water, electricity and other pipelines during construction.
[Features]
★ It has multiple detection methods: it can automatically switch and save values automatically when turned off.
★ It can automatically measure the resistance of pipelines to ground, output modulated high-frequency alarm signals, and has strong anti-interference ability, improving the detection effect of the instrument and extending the service life and lifespan of the battery.
[Detection Principle and Method]
The principle and method of detecting the direction and burial depth: sending specific high-frequency modulation signals to underground pipelines to determine their position, direction, and depth by detecting the magnetic field of the underground pipelines.
Detection principle and method:
Send specific high-frequency modulation signals to underground pipelines, form a loop with the ground at the point of damage to the anti-corrosion layer of the underground pipeline, and radiate to the ground. The radiation signal is strong directly above the damage, and based on this principle, identify the point of damage to the pipeline anti-corrosion layer.
★ Adopting the "human body capacitance method", which uses the human body as the sensing element of the leak detector. When the leak detector walks near the leak point, the leak detector emits a sound prompt. When it reaches directly above the leak point, the sound in the horn sounds, indicating a large value, thus accurately finding the leak corrosion point.
