Ultrasonic examination comprises a range of non-destructive testing techniques that send ultrasonic waves through an object or material. These high frequency sound waves are transmitted into materials to characterize the material or for flaw detecting. Most ultrasonic examination applications use short pulse waves with frequencies ranging from 0.1-15 MHz, although frequencies up to 50 MHz…

DOT pressure vessels (cylinders) require periodic inspections to evaluate the integrity and safety of each vessel. After years in use, it is important that authorized holders of a Re-qualification Identification Number (RIN) conduct a thorough examination of each vessel. Two non-destructive test methods are generally used for re-qualification: hydrostatic (volumetric expansion) and ultrasonic examination. Ultrasonic…

Many industries use compressed gas cylinders to store substances such as oxygen, propane, acetylene, or fire suppressants. Structural flaws in a cylinder can turn dangerous resulting in leaks, ruptures, or even deadly explosions. The two primary methods of testing cylinders to detect these potential flaws are hydrostatic testing and ultrasonic examination. The processes of these…

In accordance with The Code of Federal Regulations, Title 49, re-qualification of portable cylinders means the completion of a visual inspection and the tests required to be performed on a cylinder to determine its suitability for continued service. Regulatory approval of the test facility, personnel and equipment is required for portable cylinder re-qualification. Successful certification…
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…
