NDT Inspection Plugs
+ TML Point Label Sales
Nondestructive Testing under Insulation
NDT inspection plugs offer a balance of durability and reliability for repeated access to inspect corrosion under insulation (CUI).
Nondestructive Inspection plugs are speccified for EPA and OSHA testing access on storage vessels, tanks, and pipelines in power generation, processing and refining operations.
NDT Plugs (Ports / Seals) consists of an elastomer (EPDM) sleeve with metal cap, handle, lanyard, and locking ring.
Inspection Plugs are shipped w/ EPDM (ethylene propylene) sleeves. (Silicone for higher temperature available.)
Material = #5052 aluminum or #304 stainless steel.
NDT Inspection Plugs for Nondestructive testing (NDT) inspection and evaluation (NDE) of mechanical integrity + corrosion.
Inspection Plugs are designed for repeat (removable) access for NDT inspection of insulated pipes, tanks and vessels.
Once installed, the inspection plug seals the inspection access point with a metal (aluminum or stainless) cap and EPDM 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.
For Bio, Chemical, Cold Storage, Pharma, Steam, Oil & Gas, Nuclear, LNG, and Petrochem facilities, tanks, and pipelines.
