Caustic Tank (21%) Temperature Hick-Up
Caustic Tank (21%) Temperature Hick-Up
(OP)
I have a 22' diameter x 15'ht carbon steel (A36) tank. It operates at ambient (85oF) temperature under normal conditions. Built 2002 to API 650 standards with acceptable QA/QC records. Shell plate chemical composition: C=0.18, Mn=0.75, P=0.01,S=0.006, CU=0.02, Al=0.038. Current thickness measurements on the shell, roof & nozzle are at or near nominal thicknesses.
Over the weekend it was hit with 180oF for 48 hrs.
Our concern is do we have corrosion and or cracking potential.

On your 10-year 1st Internal, be sure to perform 100% MT on all welds below 6 to 8-ft up.
