Computed And Digital Radiography (Both For Weld Inspection And Tangential/Profile RT)

Computed And Digital Radiography (Both For Weld Inspection And Tangential/Profile RT)

Computed Radiography (CR) Uses A Phosphor Imaging Plate That Replaces Film In Conventional Radiography Techniques. … First, It Indirectly Captures The Image Of A Component On A Phosphor Plate, And Then Converts The Image Into A Digital Signal That Can Be Visualized On A Computer Monitor.

Profile Radiography, Technically Called Tangential Radiography Is A Radiographic Technique Used For The Determination Of Remaining Pipe Wall Thickness. Wall Thickness Measurement In Processing Pipe Is Necessary To Determine Loss Of Material Due Corrosion Under Insulation And Internal Erosion. Thickness Measurement Would Assist The RBI Expert In Making Decisions With Regards To The Safety Of Plant, Environment And Personnel.

Advantages:

• The Images Can Be Readily Shared, E-Mailed And Stored Electronically By Anyone Needing Reliability Information For The Equipment.

• The Imaging Plates Practically Eliminate Re-Shots By Providing A Greater Range Over Which Exposures Can Be Useful.

• Significant Exposure Reductions

• Reduction Of Exposure Times From 50-70% When Using IR 192

• Similar Or Better Results Are Obtained When Utilizing Se 75, Co60 And   X-Rays

• Highly Reproducible

• Images On Film Or Digitized

• Data Is Stored For Future Comparison Or Audit
