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

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

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.
