Radiographic

Radiographic ExaminationsRadiographic examination employs a source of radiation, such as an X-ray tube or a radioactive isotope, to penetrate the material and produce a volumetric image.

Methods

  • Computed Radiography
  • Conventional Film Radiography

Uses

  • Weld Quality
  • Profile
  • Castings
  • Failure Analysis

DTS is proud to be an innovative leader in this method. Through research and training, we have utilized this approach instead of other methods that are higher cost and more time consuming. This method is showcased in every industry DTS serves. The link above provides additional detail.

Ultrasonics

Ultrasonic Non Destructive ExaminationsUltrasonic examination employs high-frequency sound waves to penetrate components allowing the analyzation of reflected sound for determination of internal quality, overall thickness, and other material properties.

Methods

  • Longitudinal Wave
  • Shearwave
  • Linear Phased Array
  • Time of Flight Diffraction (TOFD)

Uses

  • Thickness
    • Boiler & Piping Surveys
    • Flow Accelerated Corrosion Studies
  • Volumetric Testing
    • This technology is utilized in many industries including refinery, gas/oil, manufacturing, fabrication, and power. It serves as a tool to help determine wastage rates of tubing as well as pipe and weld integrity.

Magnetic Particle

Magnetic ParticleMagnetic Particle examination detects discontinuities in ferrous metal at or near the surface after a magnetic field has been induced in the component and the application of a ferrite powder or liquid solution. The applied media is attracted to the magnetic flux leakage of the discontinuity. This method allows visual interpretation of the discontinuity.

Methods

  • Wet Fluorescent
  • Dry Particle
  • Contrast

Equipment

  • Yokes
  • 700 amp Machine
    • Prods & Coils
  • 6000 amp Machine
    • Prods, Coils, Head Shots

DTS performs Magnetic Particle exams in a multitude of industries including refinery, oil/gas, and power. Our experience includes piping, structural steel, turbine components, fabrication and various others.

Liquid Penetrant

Liquid PenetrantThe Liquid Penetrant method employs capillary action to expose surface flaws in any solid material. Visible or fluorescent dye on a contrasting background allows for enhanced visual inspection.

Methods

  • Visible
  • Wet Fluorescent

Technique

  • Water Washable
  • Solvent Removable

DTS performs Penetrant Examinations on various materials such as stainless steel and aluminum. Every industry we serve, including power, gas/oil, refinery, aerospace, and manufacturing, utilize this method.

Visual

Visual ExaminationsMost codes and standards require visual VT exams as the first NDE method to assure proper adherence to product design and quality. This step, if followed properly by individuals trained and certified to thoroughly inspect and disposition the components, can save a project the time and cost of performing further NDE prematurely.

Methods

  • Direct
  • Remote
    • Crawler Systems
    • Articulating Video-Scope

Equipment

  • Measuring Tools
  • Weld Gauges for Size and Fit-up
  • Specialized Lighting

We perform visual inspections prior to every NDE method. This is common in every industry we work in at every location. It is the basic starting point of every inspection.
