The US medical gases division of Linde North America has introduced ultrasonic cylinder testing which promises to save homecare companies millions. The new technology saves time, maximises efficiency and also doubles the re-qualification lifetime of cylinders.

LifeGas has harnessed Sonic+ ultrasonic examination (UE) technology to retest medical aluminium gas cylinders. LifeGas, won the first Department of Transportation exemption in the industry for the use of UE in lieu of the traditional hydrostatic testing method for re-qualifying compressed gas cylinders.

The new technology is preferable to hydrostatic testing, as it omits the need to disassemble the cylinder. Sonic+ technology operates by detecting internal cylinder flaws through the use of external ultrasonic waves.

Anthony Eafrati, LifeGas Homecare Market Manager highlighted the significance of this to the medical gases industry. He explained, $quot;This is particularly critical with medical gas cylinders which require pristine interiors.$quot;

In addition to efficiency benefits, the new technology also allows an extended cylinder re-qualification period. LifeGas has won an extension to the normal re-qualification period from five to ten years. Eafarti commented, $quot;This special permit allows aluminium cylinders to remain in service twice as long as does the hydrostatic process.

Eafarti extolled the financial benefits of Sonic+, he added, $quot;Homecare companies can cut their re-test costs in half, which can lead to substantial savings. We have one customer who will save nearly $10m over the next ten years. This is a step change in recertification that delivers real savings at a time when home medical equipment providers need it most.$quot;

The Linde Group's subsidiary operates across North America at re-qualification locations in New York, Indiana, Texas and Georgia.
