Installation Procedures

NDT Plug Installation Procedure

Locate and mark the insulation jacket where the inspection port will be installed:

  • Hole saws are best to penetrate the insulation jacket, cutting a circumference equal to the Inspection port to be installed.
  • Remove the insulation, to expose the substrate for inspection.
  • After inspection, re-insert the insulation or replace it with a high-density material.
  • Insert the EPDM or Silicone Sleeve.
    • Install the Inspection Port Locking Ring and Lanyard if equipped.
    • Insert the Port Cap to create a seal.

    Note: Caulking around sleeve for cold applications installations recommended

    Application surface should be at room temperature or slightly higher:

    • The minimum application temperature for acrylic adhesive is 58°F (15°C).
    • Clean and dry the application surface for maximum bond strength.
    • The surface should also be free of loose particulates, such as dust, dirt, and corrosion.

    Note: Acrylic adhesive requires 48-72 hours to achieve 90% of its ultimate bond strength.
