ue vs hydro
TRANSCRIPT
Residual contents do not have to be drained
Cylinders are not de-valved
Ultrasonic testing provides a more detailed analysis than the standard hydrostatic test
UE system requires less operators/ technicians
Not affected by temperature change like a hydrostatic test
DOT Approved
UE detects corrosion better than a visual inspection, which can be cursory and subjective.
“Because ultrasonic testing produces highly accurate measurements, the Department of Transportation waived the required internal visual examination for cylinders used in certain services.”
- Jerrold D. Sameth, Chief Technologist, Director of gas packaging, Matheson, Tri-Gas Welding Magazine, Feb. 2007
Did you know? Subjective visual inspection is the main cause for cylinder rejection!
Hydrotests only give an average wall thickness
THIS CYLINDER PASSED HYDRO !
Measuring the displacement of the water can only represent an average of
the cylinder’s wall thickness
A signal is emitted from a transducer; when the signal meets a flaw in the cylinder, it is reflected back to the transducer.
Flaw Scan
Thickness Scan
Actual WallThickness
Digital UE measures actual wall thickness. Gouges and pitting that don’t meet the reject requirementsin CGA C-6 won’t cause rejects. Don’t let a subjective visual throw away your good cylinders.
UE has a lower reject rate than visual!
C-scan maps assures you that indications are actual flaws. Only flaws that meet the DOT criteria will cause rejects.
Digital Wave systems are capable of handling cylinders from 3.2” D to 10.5” D, and lengths from 0” to 65”
There are no proprietary electronic components--parts can be purchased easily, worldwide.
The DOT requires at least a 10% beam overlap for UE systems; Digital Wave's system provides a 25% beam overlap.
UE systems come in two formats: digital (newer technology) and analog (older technology).
Digital systems digitize the waveforms and store them in the computer. This permits an infinite variety of analysis to be performed providing complete flexibility to adapt to your future needs. To do this with analog systems you have to redesign the electronic circuits.
Digital Wave, as the name implies, manufactures digital systems.
All UE systems are NOT created equal!
The simple, single-sensor head design and multiple-axis motion control allow for all cylinder sizes to be tested with one machine.
With Digital Wave's innovative design, just swap out the 2.25MHz sensor with a 3.5MHz sensor to test small cylinders.
No other UE machine has this capability!
Digital Wave systems scan out-of-round cylinders with ease and feature automatic cylinder size detection.
Digital Wave systems scan through most labels and bonded paint. They also won't reject on most draw marks or clear coat scratches.
Don't buy new equipment when the regulations change...
Digital Wave's design provides superior scanning flexibility and can adapt to changing regulatory requirements.
Ultrasonic Examination is:
Environmentally friendly (in some areas of the world, water from hydrotesting is considered hazardous waste!)
Uses far less water than a standard hydrotest
A single technician can run hundreds of cylinders a day!
