It uses sound waves to propagate which is unlike alternate technologies such as Eddy Current, ultrasonic, which uses probe to maintain contact with tube through out its length.
Since APRIS doesn’t use material properties for its sound pulse propagation, it’s applicable for all tube materials including ferrous, non-ferrous, graphite, composites etc.
APRIS uses air as a medium for its sound pulse propagation. Hence, its possible to inspect any tube configuration such as U bend, finned, multiple bend, D shaped tubes etc.
APRIS takes around 10 seconds to inspect a tube. So, 2000 tubes can be inspected within a shift say 8-10 hours.
25m can be covered if inspected from one end. If a tube length is greater than 25m, both ends of the tube can be inspected to cover 50m effectively. Tubes greater than 50m can still be inspected but accuracy of sizing varies.
Positional or locational tolerance: +/- 5cm
Sizing tolerance: +/-10%
The above is applicable for tubes with length of maximum 25m
If any tube exceeds 25m length
Positional or locational tolerance: +/- 5cm
Sizing tolerance: +/-20%
APRS is capable to inspect tubes from 7mm till 100mm tube ID
Yes, cleaning is the pre-requisite to carry out inspection using APRIS.
If hydro jetting (water-based cleaning) to be employed, it’s recommend to dry the tubes via air blow to avoid water stagnation. If not, it shall be reflected as blockage.
APRIS detects hole (leak), wall loss (pitting & erosion) and blockage (deposits/scales)
Hole starting from 0.5mm
Wall loss starting from 10%
Blockage starting from 5%
Sophisticated algorithms using artificial intelligence assist users to generate report within 24 hours via intuitive software.
