NDT Plug & TML Label Installation

Inspection Plugs

Locate and mark the insulation jacket where the NDT test plug is required:

  • Use a hole saw to penetrate the insulation jacket, cutting a circumference equal to the size of the NDT Inspection Plug to be installed.
  • Remove the final layer of insulation, to expose the substrate for electronic and/or visual inspection.
  • After inspection, re-insert the insulation or replace with a high density material.
  • Insert the Sleeve.
  • Note: Caulking around sleeve for cold applications is recommended
  • Install the NDT Locking Ring and Lanyard.
  • Insert the NDT Plug Cap to create a seal.

TML / UT Labels

Be sure application surface is at room temperature or slightly higher:

 

  • Minimum application temperature for the adhesive is 58°F (15°C).
  • Clean and dry the application surface for maximum bond strength.
  • Surface should also be free of loose particulate, such as dust, dirt and corrosion.
  • Note: Acrylic adhesive requires 48-72 hours to achieve 90% of its ultimate bond strength.
