API 653 In-Service Inspection Report <br /> for m m m m <br /> Pacific Ethanol HMT Inspection <br /> Tank No. T-7704 August 8,2013 <br /> Stockton, CA Page 6 of 42 <br /> SUMMARY AND REPAIR RECOMMENDATIONS (CONT'D.) <br /> SHELL (CONT'D.): The shell coating is lightly weathered and is starting to show signs of <br /> chalking. The coating is intact and no areas of failure exposing the carbon steel were <br /> noted. <br /> The next external API 653 inspection should be conducted within 5 years and no later <br /> than April 2018 (ref. API 653, Para. 6.3.2.1). Complete API 653 out-of-service inspection <br /> prior to this date would supplement the next external inspection requirement. <br /> Shell Ultrasonic (UT) testing should be conducted again within 15 years and no later <br /> than April 2028 (ref. API 653, Para. 6.3.3.2). Complete API 653 out-of-service <br /> inspection prior to this date would supplement the next external inspection. <br /> NOZZLES AND APPURTENANCES: Visual (VT) inspection and Ultrasonic (UT) testing <br /> of the nozzles and manway were performed. <br /> Shell Manway A does not have a reinforcing plate. Visual (VT) inspection of this <br /> appurtenance found it acceptable condition. This is provided as information only and no <br /> corrective action is required at this time. Consideration should be given to installing seal <br /> welded reinforcing plate next time major repairs are made to the shell 1 manway. <br /> Shell Nozzle B, C, D and F do not meet the minimum neck thickness requirements of <br /> API 650 (ref. Table 5-6, Column 3). These details have been present for an extended <br /> period of time with no issues noted and no corrective action is required at this time. This <br /> area should be monitored in future for signs of accelerated corrosion due to possible <br /> increased stress concentrations. <br /> CI'VID <br /> AUG 14 2014 <br /> APIRPTNE.00T REV 2 2326286877-7704r(Rev 1) 1102013 2:25 PM <br /> ENVIRONMENTAL HEALTH <br /> DEPARTMENT <br />
