Gulf Coast Refinery —
200 CUI Locations, 10-Day Window

Beaumont, TX · Crude Unit Turnaround · API 510 / API 572 Compliance

Act I · The Scene

200 CUI-Suspect Locations. One Refinery. Ten Days.

A Gulf Coast crude unit scheduled a 10-day turnaround with 200 identified corrosion-under-insulation suspect zones across carbon steel piping operating at 450°F service. Conventional radiography would require 72+ hours of film processing and radiation exclusion zones — incompatible with the schedule.

Act II · Technique Selection

PAUT Over Conventional RT — and Why

Phased array UT eliminated film processing, radiation exclusion zones, and single-angle blind spots. A 64-element linear array with encoded B-scan provided volumetric coverage in a single pass — no multiple film placements, no IQI recalculations per weld geometry change.

Act IV · Outcome

Zero Unplanned Shutdowns Post-Turnaround

Final disposition: 5 critical replacements, 8 monitored locations, 187 cleared. Unit returned to service on schedule. 18-month post-turnaround audit confirmed zero undetected corrosion failures.
