XHFJ-6 underground natural gas and oil pipeline anti-corrosion layer detection leak detector

XHFJ-6 underground natural gas and oil pipeline anti-corrosion layer detection leak detectorIt 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 used in China to detect the condition of the anti-corrosion coating of buried pipelines on the ground, the corrosion status of the pipeline body, and locate the corrosion points of the pipeline bodyThe instrument. It is a testing instrument used by departments such as oil fields, chemical engineering, 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.

XHFJ-6 underground natural gas and oil pipeline anti-corrosion layer detection leak detector[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 oil, gas, water, electricity and other pipelines during construction.

XHFJ-6Detection and leak detector for anti-corrosion coating of buried pipelines[function]

★ It has multiple detection methods: it can automatically switch and save values automatically when turned off.

★ It can automatically measure the ground resistance of the pipeline, output low-frequency modulation alarm signals, and has anti-interference ability *, which improves the detection effect of the instrument and extends the service life and lifespan of the battery.

The principle and method of detecting the direction and burial depth: sending specific low-frequency modulation signals to underground pipelines to determine their position, direction, and depth by detecting the magnetic field of the underground pipelines.

leak detectorDetection principle and method:

Send specific low-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 stronger directly above the damageIdentify the damage points of the pipeline anti-corrosion layer based on this principle.

★ Using the "human body capacitance method", the human body is used 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 is loud, indicating a large value, thus accurately finding the leak corrosion point.
