CRXVision: Objectives

Complying to current Weld Standards (ISO 17636-2, Class A & B,ASME Section V Article 2, ASTM, EN)

Reproduction of the Film workflow & throughputNeed for excellent image quality (BSR, SNR)Handling long plates & odd sizes at a competitive price

12


13/32

CRXVision - the result

BSR: true 35x35 pixel size, resulting in 40 BSR

First CR scanner with a BSR and SNR to comply to Weld Standards,combined with a high throughput and an increased Dynamic Range.

SNRn: >270 ! ISO 17636-2, required between 70 and 150.

Dynamic range: Much more relaxed on exposure settings: Radiography for dummies

Throughput: fully compatible with existing Rhythm platform

CRXVision: Customer Beta and demo results

Oceaneering: Panoramic Offshore pipe weld - OD 10.8" - wt 19mm crawler / OD 6.625" -wt 15.9mm crawler SE75 / OD 6.625" - wt 9.5mm - Crawler

Exposure conditions (SOD) not compliant with ISO 17636-2CLASS A/B - Geometric Unsharpness >> required wire

Performance equivalent or better than Film (D7)

Scotia Automated Inspection Services: Panoramic

Offshore pipe weld - OD 34" - wt 12.5mm - X-ray crawler 200kV

ISO 17636-2 CLASS-B reached

National Grid (UK): DWSI

Pipeweld: OD 8" - wt 12mm - X-ray 264kV

ISO 17636-2 Class- B reached

Force Copenhagen: SWSI

IQI test: FE wt: 1mm -10mmISO17636-2 CLASS B except for FE wt=4mm Class A exceed

TEAM Houston - Acuren

Team Industrial Services and Acuren

Plate Samples from 0.375 to .600 thick with Iridium 192

Plate Samples 5 and 10 thick with CobaltPipe Weld Samples from 2 to 6 diameters with Iridium 192

ASME Code Quality Achieved

Acuren/Exxon:

CRxVision specd by Exxon for weld inspection of a new pipelineon Alaska North Slope: 12 diameter, carbon steel pipe

Acuren used two CRxVision Systems to inspect all the welds ofmany miles (24x7 for over 2 months).

Project is being completed now and was a success.

17/32

Key features,

Weld Standard Image quality @ 35> High BSR High Resolution scanning @ 35> Excellent defect recognition>

Spatial Resolution: up to 40 (13D+

)

Standard Resolution scanning @ 70> Lower resolution, even higher throughput.

High speed scanning > 42 plates / hr. 14x17 @ 70> 14 plates / hr. 14x17 @ 35

17


18/32

Key features,

No Gain settings needed>

Simplified workflow> Increased Dynamic Range

Multiple plate scanning

Increasing throughput x2, x3, x4 > 135 plates / hr. 10x40cm or 3,5x17 @ 70> 42 plates / hr. 10x40cm or 3,5x17 @ 35

Fully automatic image cropping, no time loss> E.g. 3 ea. 3,5x17inch or 5ea. 6x48cm

Flexible plates with ferro magnetic backside> No memory effect after being bent> Backscatter reduction

CRXVision : SNRN vs. Dose @ SR mode

Conclusion:o Flattening (270 SNR N) @ 1000 Gy 30000 Greyvalueo No need to go higher in Greyvalue

Normalised SNR with CRxVision @ 70 + IPS vs. CRxFlex. (90kV-1,5mmCu)


26/32

Normalised SNR with CRxVision @ 35 + IPU vs. CRxFlex. (90kV-1,5mmCu)

CRXVision : SNRN vs. Dose @ HR mode

Conclusion:o Flattening (300 SNR N) @ 4000 Gy 12000 Greyvalue (No need to go higher)o Resulting in much higher Dynamic Range (e.g. stepwedge)


27/32

CRXVision: Features Summary

70 and 35 scanning: Covering stringent weld Standards

Highly flexible new imaging plates with FE-oxide back: Contact Less Plate Transport (life time optimization) Improved backscatter reduction
