Measuring substrate thickness through thick coatings

· Function of the Anti-Corrosion Layer

   The external anti-corrosion layer of long-distance oil and gas pipelines can provide good protection for the pipeline.

   Ensure the stability of the energy transmission process and reduce the occurrence of pipeline leakage accidents,

   to ensure the safety of people's lives and property.

Measurement Difficulties

 

 

Measurement Principle

· Coating Penetration Measurement

   The coating penetration function of the ultrasonic thickness gauge is used to measure the net substrate thickness of pipes, boxes, or other metal materials with paint or coating on the surface.

   No need to remove the protective coating, quickly and accurately measure metal thickness! This function is achieved by measuring the two consecutive bottom surface echoes of the substrate.

Probe Selection

· Special Probe for Thick Coating Penetration

   Can accurately measure metal thickness through coatings of 20mm or even thicker,

   and is suitable for use on flat surfaces, curved surfaces, or pipes. It can make the detection work

   faster and more efficient.
