NDT Inspection Plugs

NDT Inspection Plugs for Nondestructive inspection, testing, and evaluation (NDE) of mechanical integrity (corrosion) inspection under insulation.

Removable/reusable NDT inspection plugs allow access to inspect for corrosion under insulation (CUI) on storage vessels, tanks, and pipelines in processing and refining operations.

NDTspek’s Inspection Plugs consists of an elastomer (EPDM) sleeve with metal cap, handle, lanyard, and locking ring.

The plus sleeve is available in either EPDM (ethylene propylene) or silicone for higher temperature applications.

Metal caps are available in #5052 aluminum or #304 stainless steel.

For use in Bio, Chemical, Cold Storage, Pharma, Steam, Oil & Gas, Nuclear, LNG, and Petrochem facilities, tanks, and pipelines.

NDT Inspection Plugs do not require transition gaskets for corrugated applications and no special configurations for smaller diameter pipe applications.

Inspection Ports are designed for frequent (repeat) visual and electronic inspection access to insulated pipes, tanks and vessels.

Once installed, our inspection plugs seal the access point with a metal (aluminum or stainless) cap and elastomer (or silicone) sleeve, creating a moisture-proof barrier.

The barrier protects against corrosion under the insulation (CUI), plus chemical and UV exposure of the elastomer or silicone sleeve.
