How to Do Fluorescent Mag Particle Inspections [Video]
Learn about the magnetic particle inspection method of nondestructive testing, including basic steps for NDT with fluorescent magnetic particles using a magnetic wet bench..
Many people, even some NDT experts, do not realize what an important role NDT carrier fluid plays in the performance and dependability of a magnetic particle inspection.
In this article, we explain what an NDT-approved carrier is and what sets it apart from commonly used, non-approved base oils.
What is an NDT carrier fluid?
An NDT carrier fluid is the fluid in which fluorescent and nonfluorescent magnetic particles are suspended to facilitate their application.
Also known as a petroleum-base suspension vehicle.
What makes an oil carrier categorized as NDT material?
What makes an NDT carrier fluid different from a non-NDT petroleum-base oil like kerosene or Isopar M?
A NDT Carrier fluid is:
What is the safe zone a carrier’s flash point should be within?
NDT carrier fluid should have a flash point above 200°F / 93.3°C. This high flash point is safe for use in most facilities, while promoting a safe work environment for NDT operators.
Why is it important to have a high flash point?
A high flash point improves operator and plant safety, and helps prevent fires. OSHA typically requires a flash point at or above 200°F / 93.3°C for fluids that are used in open tanks.
What are the dangers of using an oil with a lower flash point?
What are dangers of not using an NDT-approved carrier?
