Inspection Plug

Standard Inspection Plugs are designed to assist in Non Destructive Testing (NDT) programs on insulated and non-insulated pipe and vessels. These plugs are designed to withstand temperatures up to 500º F and are available in both Aluminum and Stainless Steel versions. They also provide a method of sealing test holes in insulation for ultrasonic testing of metal thickness or visual inspection for external corrosion of insulated equipment in hot or cold service.
