How to evaluate a pitted area in an Aboveground Storage Tank

Jul 27,2015 API 650 tanks Merging Weld With Plate Surface#0183;Having this in mind,how can we evaluate shell pitting in tanks? Please keep reading,as the explanation in the API 653 is very short.API 653 says the following about pitting in tank shells.4.2.3.2 Areas that are pitted shall be evaluated to determine the likelihood of through-pitting occurring prior to the next scheduled internal inspection.Fundamentals of Double Bottom Tanks PetrolPlazaJan 01,2000 API 650 tanks Merging Weld With Plate Surface#0183;Appendix I of API 650 provides the requirements for tanks with release prevention barriers (RPBs).By far the most common form of Appendix I tank bottoms are double bottoms.These are used on old single bottom tanks that now require new bottoms.However,API 650s Appendix I also addresses RPB tank bottoms for new tanks.File Size 381KBPage Count 82-12,API 650,Oil Storage Tanks - LANL Engineering LANL Engineering Standards Manual ISD 341-2 Volume 2,Welding Fabrication Procedure WFP 2-12 API 650,Oil Storage Tanks Chapter 13,Welding Joining Rev.1,10/10/06 5.The edges of welds shall merge with the surface of the plate without a sharp angle.
