NDT Inspection Plugs

NDE Resource Center

Education

The NDT Resource Center is an Iowa State University website with a wide-variety of information about Nondestructive Evaluation (NDE) and Nondestructive Testing (NDT).

NDT Resource Center for Nondestructive Evaluation

Their website has three main objectives:

1) To serve as an educational resource for students and instructors of two-year nondestructive testing (NDT) programs, and others with an interest in NDT technology.

2) To promote NDT as a career field to students, teachers and counselors in junior and senior high schools. And to encourage students to study math and science in preparation for careers in high-technology fields, such as NDT.

3) To serve as a resource for review, reference and sharing of information by the NDT community at-large.

TML / UT Label Specs

Standards + Specs, Testing + Inspection

Thickness Measurement Location (TML) and Ultrasonic Testing (UT) labels are essential for identifying inspection points in various nondestructive testing (NDT) applications.

Material and Coating:

  • Material: 3.5 mil matte silver mylar polyester.
  • Coating: 1.0 mil UV laminate. This coating resists degradation from scuffing, chemicals, moisture, and wide temperature fluctuations.

Adhesive Properties:

  • Type: High-performance acrylic adhesive.
  • Features: Provides excellent bonding to metals, HSE plastics, and a variety of painted and textured surfaces.

    It also has low-leachable chloride, fluoride, and sulfur, which is important for preventing contamination.

Temperature Resistance:

  • Continuous Temperature Range: -40°F (-40°C) to 300°F (149°C).
  • Minimum Application Temperature: 58°F (14°C).

Label Variants and Warnings:

  • Labels come with various inscriptions such as “DO NOT REMOVE, NDT Inspection Point,” “TML Location, Do Not Remove,” and “UT Location, Do Not Paint.”

    These warnings ensure proper handling and identification of the inspection points.

These specifications ensure that TML and UT labels are durable and effective in harsh environments, making them suitable for various industrial applications such as in petroleum refining, chemical processing, and power generation.
