NonDestructive Testing Inspection Plugs

NDT Plugs/Seals, TML Labels & Couplant

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

TML labels are designed to identify and access Thickness Measurement Locations on insulated and non-insulated pipes and equipment, to monitor structural integrity.

The 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.

Preventive maintenance efforts have been underway for some time to monitor structural integrity of pipe and equipment in the process industries. In its most basic form a visual inspection is made to assess surface corrosion. Increasingly, electronic testing (ultrasonic, infrared, vibration, etc.) is employed.
