Ultrasonic Testing (UT)

5 Star Testing, Inc. offers a wide range of applications that involve ultrasonic testing (UT). Ultrasonic testing can be used for detecting discontinuities and flaw detection, to taking thickness measurements. Common uses of conventional ultrasonic testing are:

  • Ultrasonic Thickness Testing including:
    • High Temperature Parts
    • Ability to read through coatings
    • Coating thickness measurements
    • Internal Oxide/Scale measurements
  • Weld Inspection
  • Shaft / Spindle Inspection
  • Bolt Testing
  • Cladding / Delamination Inspection

Thickness testing is most common on tanks, vessels, and piping to detect corrosion, erosion, and pitting. It is common that these items are coated with a protective layer. Our instruments have the ability to read through coatings. We are able to take measurements that will not include the coating, giving more accurate readings and eliminating the need to remove coating. Another thickness testing method utilized is internal Oxide/ Scale measurements, this application measures the buildup of oxide or scale on the inside diameter of boiler tubes, which can result in overheating.

Weld inspection using conventional ultrasound is uncommon these days with the advancements in phased array ultrasonic testing. 5 Star Testing offer numerous services involving phased array, click here to learn more.

Shaft / Spindle & Bolt inspection is critical for long term use. Our equipment is capable of inspecting up to a 100” range. Our technicians have the experience to sort through the signals from tapered shafts and detect cracking or relevant indications.

Cladding / Delamination Inspection can be performed on tanks, vessels, piping, etc. With appropriate access, our technicians can detect and size delamination or lack of fusion on multiple types of cladding like, explosion cladding. Take measurements of the cladding to monitor for erosion or corrosion.
