DUBAN DB22-CM222H Anti-corrosion layer Thickness Gauge

Product Applications

 Anti-corrosion layer Thickness Gauge is a portable measuring instrument, which can quickly, without damage, and accurately measure the thickness of coating and plating layers; It can be used both in the laboratory and in the engineering site; It is widely used in manufacturing, metal processing industry, chemical industry, commodity inspection and other testing fields; It is an instrument that needs to be used in the material protection profession.

The anti-corrosion layer Detector adopts the multi-frequency tube current method (also known as the AC current method, including the AC current attenuation method and the AC potential gradient method), under the premise of trenchlessness, by measuring the multi-frequency current in the pipeline and the leakage current in the soil at a certain point distance on the ground, it can quickly and economically find out the pipe section with anti-corrosion layer defects, and the A-frame can accurately locate the defect points of the anti-corrosion layer, and can evaluate the insulation performance of the anti-corrosion layer by classification, so as to scientifically, accurately, Economically test the comprehensive performance of the anti-corrosion layer and provide suggestions for the repair and maintenance of the anti-corrosion layer to ensure the integrity and integrity of the anti-corrosion layer.

The multi-frequency tube middle current method is a relatively mature anti-corrosion layer detection technology at home and abroad, and engineering practice has confirmed that DM is a reliable equipment for pipeline detection work such as finding and locating pipeline anti-corrosion layer defects, evaluating the insulation status of anti-corrosion layer, accepting the construction quality of anti-corrosion layer, and finding pipeline lap and short-circuit faults.

For oil theft clips in oil pipelines, metal Detectors can be used to assist in detection. The metal Detector is a magnetometer, which can detect the remanent magnetic field of magnetic metal, with the characteristics of ultra-high sensitivity, large bathymetry, automatic elimination of interference magnetic field, etc., and has obvious signal response to the oil (gas) clip, which is a reliable auxiliary tool for finding and locating the metal pipeline and the oil (gas) clip.

For the oil (gas) theft clip that has not been insulated and is in contact with the soil, due to the pipeline current leakage at the oil (gas) theft point, the pipeline current and leakage current can be measured along the pipeline with DM pipeline anti-corrosion layer Detector and A-frame first, find and locate the obvious pipeline current anomaly and leakage current anomaly, and then use a metal Detector to measure and compare the magnetic anomalies of each anomaly one by one, and determine and accurately locate the oil (gas) theft card after elimination and distinction. Regular inspection of pipeline anti-corrosion layer, and comparative analysis of time series of pipeline current detection data are helpful to timely detect abnormal pipeline current caused by oil (gas) clips.

For the stolen oil (gas) clips that have been insulated or are not in contact with the soil, the metal Detector can be used to directly find and locate the suspected pipe section or the pipe section with surface traces.
