Coating thickness gauge test the anti-corrosion coating thickness

LS221 coating thickness gauge is also called coating thickness meter and paint thickness meter. It is a professional instrument for measuring the thickness of metal surface coatings. The host and the probe adopt a separate design, which is convenient for viewing data while testing under complex test conditions. It can be used in the laboratory and engineering field.

  • There are only four types of ferromagnetic metal elements at room temperature: iron, cobalt, nickel, and thorium.
  • Common non-ferromagnetic metals: copper, aluminum, magnesium, zinc, chromium, etc.
  • Hall effect: can be used for the measurement of non-ferromagnetic coatings on ferromagnetic metal substrates.
  • Eddy current: can be used for the measurement of non-conductive coatings on non-magnetic metal substrates.

The actual anti-corrosion operation is based on the specific conditions of the inner wall pipeline and the outer wall pipeline. Since the inner wall pipeline is in close contact with natural gas and oil, the frictional resistance should be as small as possible. A thinner anti-corrosion coating can strengthen the adhesion of the coating to the inner wall of the pipeline, and occupy as little as possible the internal volume of the pipeline. In most cases, we will find that the thickness of the anticorrosive coating on the inner wall of the pipeline is about 0.2mm by using a coating thickness gauge.
   Because the outer wall pipeline is in contact with nature or soil, it needs relatively strong wear resistance. In addition, the temperature dissipation and hardness of the outer wall pipeline are also important considerations. A slightly thicker anti-corrosion coating can substantially increase the overall hardness of the pipeline. The actual thickness of the anti-corrosion coating can be known by measuring with a coating thickness gauge, which can give strong guidance for maintenance work.
The high-performance coating thickness gauge can help people determine whether the thickness of the pipeline anticorrosive coating meets the requirements. Linshang Technology's LS223 coating thickness gauge has strong corrosion resistance and wear resistance, and is used for long-term underground pipeline anticorrosion The coating thickness measurement is very suitable. At the same time, its operation is quite simple, and the instrument can be used directly after zeroing.
