Corrosion & Erosion
• Ring Joint anges have had signicant cracking
from mechanical and Stress Corrosion Cracking
• Typically discovered by PT or manual UT after
anges have been opened during Turnaround.
May extend unit downtime
• PA-UT signicantly enhances detection and sizing
of cracking damage while vessel is in service or
just o line to allow for repair/replace planning
• See Pages 7 - 10 for general description
• API 653 mandates periodic internal tank oor
inspection with volumetric assessment
• Magnetic Flux scanners provide rapid general oor
condition assessment
• Phasor DM can rapidly “prove-up” scanning results
with greater detail than conventional UT
• See Pages 9-10 for general description
• Chemical and Process injection without proper
control has been responsible for signicant indus-
try incidents
• API 570 mandates enhanced inspections of spe-
cic locations downstream of these injections
• Rightrax permanently mounted sensors can be
installed in these locations and provide continuous
thickness and prole readings in these locations
• System installation can be responsive to process
changes without deploying personnel resulting in
increased data integrity at reduced costs
• See Pages 15 - 18 for general description
High-Pressure Piping Ring-Joint Cracking
Remote Visual Inspection/Ultrasonic Testing (RVI/UT)
Tank Bottom Pitting
Ultrasonic Testing Phasor DM (UT)
Injection Point Corrosion
Rightrax Installed Sensors (UT)
Ring Joint Cracking can be signicant enough to neces-
sitate replacement. PA –UT can be used to detect and
size damage on line
Phasor DM can be used to accurately quantify the extent
and severity of general wall loss detected in tank bottoms
by global scanners
Rightrax sensors can be applied directly over an Injection
Point area of concern and provide continuous wall thick-
ness monitoring
