Use MOBILEAE  to recertify steel cylinders economically in lieu of hydrostatic testing. MOBILEAE uses acoustic emission technology (AET) to test cylinders on or off trailers. MOBILEAE is the economical alternative for cylinder recertification. Tubes are tested on the trailer using a lower test pressure than hydrotesting.

WINS’ Acoustic Emission Testing complies with U.S DOT requirements; is faster and more economical than hydro testing, and can inspect up to 16 cylinders at once.
WINS’ U.S. DOT special permit # 14584 allows for AET on DOT 3A, 3AA, 3AX, 3AAX and 3T cylinders. Testing in Canada is done under permit # TC-SU-6077.

Reports are automatically generated using our System for Tube Testing And Reporting STTAR software.  The software is used to track test pressure and acoustic events from active flaws in the cylinder’s wall.  Acoustic events originating from active flaws in the cylinder are identified and located for follow-up ultrasonic testing.  Results from up to 16 tubes may be viewed simultaneously.
Follow-up ultrasonic inspection is required only if the acoustic emission test detects an active flaw in the cylinder.  Both our AE and UT inspections use the latest ASME standards as guidelines.
AE Inspection Procedure
Tube Trailer Readout renderingWINS AE inspection procedure follows the ASTM E 1419 Standard Test for Examination of Seamless, Gas-Filled, Pressure Vessels Using Acoustic Emission and ISO 16148. Our instrumentation is calibrated on each tube tested.  After calibration, the tubes are loaded to 110%.  During this loading period active flaws, if present, in the cylinder’s wall will emit high frequency sound waves.  These sound waves travel longitudinally in the cylinder until they are detected by the by piezoelectric sensors located at each  end of the cylinder.  The relative time-of-flight of the sound wave at each transducer is used to locate the flaw longitudinally.
Follow-up UT Inspection
Tube Trailer Image flawA follow-up ultrasonic inspection is required only if the AE inspection detects an active flaw during the loading period.   Our inspection procedure follows ASTM E 2223 Standard Practice for Examination of Seamless, Gas-Filled, Steel Pressure Vessels Using Angle Beam Ultrasonics.

These follow-up tests use 45-degree and 70-degree shear waves to locate and size detected flaws accurately.   Ultrasonic transducers are scanned longitudinally and circumferentially along the cylinder’s OD during this test.
