NDT Plug & TML Label

Installation / Application Procedures

Inspection Plug Installation

 

  • 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.(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 Label Application

Be sure application surface is at room temperature or slightly higher. The minimum application temperature for the adhesive is 58°F (15°C).

Clean and dry the application surface for maximum bond strength. The 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.

Several weeks are required to achieve 100% of ultimate bond strength. Higher initial bonds are achieved through increased rub down pressure.
