Ultrasonic testing 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. One common application for this test method is ultrasonic thickness measurement, which is used to ascertain the thickness of an…

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…
Ultrasonic Evaluation of portable cylinders uses ultrasonic waves as a non-destructive process that uses bursts of ultrasonic energy into the cylinder to detect flaws. A defect such as an internal or external crack or thinning wall would be detected by reflecting the sound wave to the detector and displaying what the flaw is on the…
Ultrasonic testing provides tremendous advantages over hydrostatic testing. These advantages include financial savings, cylinder integrity, environmental benefits, enhanced safety, and maintenance of product integrity in the cylinders. Ultrasonic testing is no longer a new, unproven concept in cylinder testing; it has been in the field for over fifteen years and has become the preferred test…
Ultrasonic Examination is the most popular and reliable test method for portable cylinders and offers several advantages. Ultrasonic Examination eliminates the need for valve removal and internal visual inspection, thus allowing the cylinder to be tested with residual product. Hydrostatic testing and ultrasonic examination are the two test methods generally used to re-qualify cylinders. Test…
Ultrasonic Examination is the most popular and reliable test method for portable cylinders and offers several advantages. Ultrasonic Examination eliminates the need for valve removal and internal visual inspection, thus allowing the cylinder to be tested with residual product. DOT pressure vessels (cylinders) require periodic inspections to evaluate the integrity and safety of each vessel….
