NDT Inspection Plugs
NDT Inspection Plugs engineered for monitoring Corrosion under Insulation (CUI) and mechanical integrity.
Inspection plugs seal access points to NDT points for EPA/OSHA inspection and testing.
- Prevent Chemical and UV exposure
Inspection Plugs come standard with removable aluminum or stainless steel metal caps for repeat access.
Inspection plugs are engineered for Nondestructive Testing (NDT) of insulated pipe, pipelines, storage tanks, pressure vessels, petrochemical, oil and gas, steam and nuclear power generation facilities.
- Inspection for Corrosion Under Insulation (CUI).
- Ozone and weather UV resistant.
NDT Inspection Plug Sizes
Diameters: 1.5″ | 2.5″ | 3.0″ | 5.0″
(38 | 64 | 76 | 127 mm)
Note: NDT Plugs can be installed on smooth or corrugated insulated jacketing.
Locate and mark the insulation jacket where the inspection plug will be installed:
- Hole saws are best to penetrate the insulation jacket, cut a circumference equal to the plug to be installed.
- Use either tin snips or a holesaw to penetrate the insulation jacket with a diameter equal to the size of the Inspection Plug.
- 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 Plug Locking Ring and Lanyard if equipped.
- Insert the metal cap to create a seal
Note: Caulking around sleeve for cold weather applications recommended
