• WHAT IS NDT (NON-DESTRUCTIVE TESTING)?

  • NDT stands for Non-Destructive Testing.
  • It refers to an array of inspection methods that allow inspectors to evaluate and collect data about a material, system, or component without permanently altering it.
• THE IMPORTANCE OF NDT

  • Savings - The most obvious answer to this question is that NDT is more appealing than destructive testing
  • Safety -NDT is also appealing because almost all NDT techniques (except radiographic testing) are harmless to people.
  • Efficiency -NDT methods allow for the thorough and relatively quick evaluation of assets
  • Accuracy - NDT methods have been proven accurate and predictable, both qualities you want when it comes to maintenance procedures meant to ensure the safety of personnel
• three different methods that inspectors use to gain access to hard-to reach locations or locations at height:

  • Scaffolding - The use of scaffolding requires inspectors to work at height in person in order to collect inspection data.
  • Rope access - The use of rope access also requires inspectors to work at height in order to collect inspection data.
  • Drones - Inspectors can use drones to collect inspection data remotely, allowing them to remain safely outside of confined spaces or safely below locations at height.
• NDT CODES AND STANDARDS

  These standards and codes typically require inspections to be conducted periodically following specific guidelines. For the most assets that present the greatest risk

  • API (American Petroleum Institute)
  • ASME (American Society for Mechanical Engineers)
  • ASTM (American Society for Testing and Materials)
  • ASNT (American Society For Nondestructive Testing)
  • COFREND (French Committee for Non-destructive Testing Studies)
  • CSA Group (Canadian Standards Association)
  • CGSB (Canadian General Standards Board)
• Non-Destructive Testing (NDT) is used to collect information about a material in ways that do not alter it (i.e., without destroying it).

  Destructive Testing (DT) is used to collect information about a material in ways that do alter it (i.e., destroy it).
• NDE (non-destructive examination or non-destructive evaluation)

  NDI (non-destructive inspection)

  The NDE full form is non-destructive examination or non-destructive evaluation, and the NDI full form is non-destructive inspection.
