Key Reasons For Utilizing Ultrasonic Examination When Re-qualifying Portable Cylinders

Travis Jolliff

It is important that authorized holders of a Re-qualification Identification Number (RIN) conduct a thorough examination of each DOT portable cylinder as part of re-qualification. Two non-destructive test methods are generally used for re-qualification: hydrostatic testing and ultrasonic examination.  Ultrasonic Examination offers several advantages to equipment operators and is the preferred re-qualification methodology because it requires access to only the outer surface of the material, provides deep penetration and has high sensitivity.

Key reasons for utilizing ultrasonic examination

  1. Reliable and Useful Test Data: The ultrasonic examination equipment locates and quantifies flaw size and accurately measures wall thickness.
  2. Minimum Down Time: Ultrasonic examination testing can be done without draining the gas product out of the cylinders. After the test, the cylinders can immediately be returned to service without the wasted steps required when hydrostatic testing.
  3. Limited Risk of Contamination: Ultrasonic examination eliminates the need for valve removal and internal visual inspection, thus  allowing the cylinder to be tested with residual product.
  4. Inexpensive: Quick testing and zero risk of contamination minimize downtime.
  5. Test Integrity: Ultrasonic examination has been used on pressure vessels for over 20 years without incident. Ultrasonic examination complies with re-qualification requirements of the United States Department of Transportation (DOT). Ultrasonic examination is also recognized by ISO standards and other international regulatory bodies.
