Locate and mark the insulation jacket where the test is required.
Use either tin snips or a hole saw to penetrate the insulation jacket with a circumference equal to the size of the NDT Inspection Plug to be installed.
Remove the final layer of insulation in the safest and most convenient manner (using your hand or knife) 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 the sleeve for cold applications is recommended.)
Install the Locking Ring and Lanyard (i.e. if applicable).
Insert the Plug Cap to affect a seal.
