In the name of GOD The Advanced Non-destructive testing and evaluation pp Dr.M.Farzam Winter 2018 PUT Petroleum University of Technology www.farzamcorrosion.blogfa.com In the loving memory of Dr. Shahid Mostafa Chamran
The advanced ndt includes: 1-digital radiography 2-laser beam inspection 3-infrared thermography 4-acoustic emission 5-ultrasonic testing 6-intelligent pigging “The results are processed by engineers to lower the risks , to lower the hazards and advance maintenance”
1-Digital Radiography The left shows the apparatus and defective pipe section. The right photo shows more defects.
D.R. coupled with a software: “Windows Leveling” makes a better analysis:
The Right Photo is Processed with “Windows Leveling”
You may “Combine” the two Images to Sharpen the Defects
2-Laser Beam Triangulation Technic to make a Better Seam “Welding” Large Diameter Pipline Pipe weld setup
The Laser “Tracking” for a Sound Weld
Laser beam “Size” evaluation: Cars Brake Pad
Laser “Crack inspection” in Composite Vessel
In service Pipeline “crack Inspection” cracks
3-Infrared Thermography: The Thermally Activated “Flaws” are Detected
Where Does IR Stands?
The Thermo-modular(Right)and Image(Left)
Aero plane Cockpit Inspection crack
Aero plane Engine Inspection
Differentiated Defect Size
4-Acoustic Emission: HIGH FREQUENCY “elastic waves” emanating from advancing crack
A REAL CASE
5-Ultrasonic testing: use of transducer and oscilloscope
Searching for Surface Cracks
Phased array: electronically controlled
6-Intelligent pigging: uses “magnetic flux” leakage detector or “electromagnetic acoustic” transducer
Defect
Computer aided data analysis: just good enough for “rbi” super positioning
“Confidentiality must not harm HSE” Concluding remarks: 1-advanced software aided ndt are just fine. 2-standards: api, iso, nace, igs, ips, …. Must be applied. 3- RBI, PM, …… are recognized tools for technical inspection and corrosion management performances. “Confidentiality must not harm HSE”
Thanks for your patience GOD BLESS YOU
