API 653 In-Service Inspection Report <br /> for mmmm <br /> Pacific Ethanol HMT Inspection <br /> Tank No. T-6102 August 6,2013 <br /> Stockton, CA Page hof 46 <br /> SUMMARY AND REPAIR RECOMMENDATIONS (CONT'D.) <br /> SHELL (CONT'D.): The next external API 653 inspection should be conducted within 5 <br /> years and no later than April 2018 (ref. API 653, Para. 6.3.2.1). Complete API 653 out- <br /> of-service inspection prior to this date would supplement the next external inspection <br /> 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 reinforcing pad is located over a 3-plate weld joint that does not meet <br /> the requirements per API 650, Para. 5.7.3.4 <br /> • Shell Nozzles B, D, F, H, K, and L do not have reinforcing plates. Visual (VT) inspection <br /> of these appurtenances found them in acceptable condition. This is provided as <br /> information only and no corrective action is required at this time. Consideration should <br /> be given to installing seal welded reinforcing plates under each support the next time <br /> major repairs are made to the shell or when hydrostatic testing is required for other <br /> reasons. <br /> Shell Nozzles B and F have centerline elevations from the center of the nozzle neck and <br /> the bottom edge projection that is less than that required by API 650, Para. 5.7 and <br /> Figure 5-8. <br /> Nozzles B, C, D and F do not meet the minimum neck thickness requirements of API <br /> 650 (ref. Table 5-6, Column 3). These details have been present for an extended period <br /> and no corrective action is required at this time. This area should be monitored in future <br /> for signs of accelerated corrosion due to possible increased stress concentrations. <br /> The automatic gauge check knob is not functioning properly. Consideration should be <br /> given to replacing parts as needed and to having automatic gauge properly maintained <br /> and serviced. <br /> RECEIVED <br /> AUG 14 2014 <br /> APIRPTNE.DOT REV 2 232628687E102r(Rev 1) 11IM0131:10 PM <br /> ENVIRONMENTAL HEALTH <br /> DEPARTMENT <br />
