NDT Inspection Plugs

Specified, Engineered Nondestructive Testing (NDT) plugs for inspection of corrosion under insulation (cui) requires removable inspection plugs, engineered for repeat access in hazardous environments.

Aluminum (#5052) or Stainless Steel (#304) inspection plugs are specified to provide durability, reliability and long-life to monitor corrosion under insulation (CUI) a crucial issue in process and refining industries.

Our plugs are designed for storage tanks, pressure vessels and pipelines for petrochemical, oil and gas power generation to maintain a seal under high pressure, and difficult environments.

Inspection Plugs are capable for repeated removable access for inspection of insulated pipes, tanks and vessels.

Once installed the inspection plug seals the inspection access point with a metal (#5052 aluminum or #304 stainless steel) cap and EPDM elastomer sleeve, creating a moisture-proof barrier.

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