NonDestructive Testing (NDT) Inspection Plugs are used for Process Safety Management and Mechanical Integrity testing in the refining, chemical, petrochemical, paper and pulp, and food processing industries.

NDT PlugsNDT Plugs (Ports/Seals) allow preventive maintenance efforts to monitor structural integrity of pipe and equipment in the process industries. Inspection is made to assess surface corrosion and vessel integrity.

  • Increasingly, electronic testing (ultrasonic, infrared, vibration, etc.) methods of inspection are employed.

  • Thickness Measurement Location Label

    NDT Plug Exploded View TML / UT labels are designed to identify and access Thickness Measurement Location testing points on insulated and non-insulated pipes, to monitor structural integrity.

    NDT PlugsThe typical TML label is 3.5 mil matte silver mylar polyester material. The matte coating resists degradation from scuffing, chemicals, moisture and wide temperature fluctuations.

  • The adhesive is a high performance acrylic for excellent bonding to metals, HSE plastics and a wide variety of painted surfaces.
