Magnetic Steel Pipe Thickness Gauge

The magnetic steel pipe thickness gauge utilizes the principle of magnetic induction, where the probe generates a magnetic field, and the wall thickness is calculated by measuring the attenuation of the magnetic field by the steel pipe. It is used to detect the thickness of the anti-corrosion coating on steel pipes or the condition of pipe wall corrosion, and is suitable for on-site non-destructive testing in applications such as oil and gas pipelines and building steel structures.
Selection
When selecting, consider that the measurement range should cover the thickness of the object being measured, the instrument should be suitable for field or factory environments, the accuracy should meet the standard error within 0.1mm, the probe shape should match flat or curved surfaces, the main unit should be portable and support data storage, and calibration must comply with national standard specifications.
