Flaw Testing, flawlessly done

The Cyl-Sonic Digital Industrial System scans through paint and most clear coatings to detect potential pits, cracks, corrosion and gouges.  In addition, the system measures and detects lost cylinder wall thickness as well as identifies undesirable moisture inside the cylinders

Wheel Probe Technology

The ultrasonic wheel probe includes nine complementary high-frequency transducers - the most integrated transducers in one unit in the industry - that search for flaws in traverse, longitudinal and oblique directions.  This ensures 100% coverage of required exam volume and area.  The four oblique transducers excel in detecting any moisture droplets inside cylinders.

Safer to Operators and Environment

Unlike hydrostatic testing methods, ultrasonic examination eliminates the need to remove hazardous gases from cylinders, helping protect both your operators and the environment.  The method does not require valve or O-ring removal, so there is less need for valve replacement as well as reduced cylinder neck thread damage.

Ultrasonic examination also eliminates the need to introduce water into the cylinders, helping prevent product contamination and elimination or minimizing the number of post-re-qualification cylinder treatment processing steps.

One Machine, Many Cylinder Types

The Cyl-Sonic Industrial system handles a wide range of outside diameters, lengths and materials which means you can inspect most cylinder types using a single machine. A built in calibration cylinder stage, which can be configured to the left or right side of the machine, allows for automated and efficient cal-in and cal-out procedures.

Saves Time, Lower Costs and Productivity through Automation

The Cyl-Sonic Industrial saves on personnel costs.  Since operators don’t need to spend time drying and re-valving the cylinders, daily production levels can be much higher.  The cost per cylinder test is lower for UE testing than hydrostatic testing.

To meet your high-volume, high-productivity needs, the system includes optional decks or tables that allow staging and simultaneous loading/unloading of cylinders while the automated testing process continuously operates. Pneumatically operated up-enders and down-enders assist with the handling of large cylinders.

Calibration Standards ensure Accuracy

Each system uses calibration cylinder standards with simulated flaws. This allows accurate comparison testing against known simulated flaws.

Software control and record retention

The Cyl-Sonic Cylinder Test application has been updated to support Nordco’s high definition, digital control electronics.  The software allows the operator to control all axis motion, including position, rotation, and sensitivity.  Calibration setups are stored and reused.  The software displays real-time scanning test results showing the locations of any detected flaws; the system also alerts the operator about a cylinder’s pass/fail status.

The Cyl-Sonic Industrial can be easily customized to integrate with any or all of the following operational processes:

  • Database Bar-coding
