Successful UT Examination of a Modified Storage Tank Shell

As part of a 25-year non-intrusive inspection strategy for a newly constructed API 620 ammonia storage tank the modified shell-to-bottom weld was recommended to be examined using an UT technique.The modification of this corner weld comprised a novel design of a double-sided full penetration fillet weld specified to exceed the tank minimum design code requirements.Study 36 Terms API 653 - Section Flashcards QuizletThe tank is to be used to store a product that causes sterss corrosion cracking (such as amine).Thickness of the bottom shell plate is one inch (first shell course).The heat is applied to the welds,but only 1025F temperature can be obtained.How long must this tempreature be held on the bottom plate welds to obtain the desired results?Some results are removed in response to a notice of local law requirement.For more information,please see here.Previous123456NextWelded Steel Tanks for Oil Storagemanufacturers of welded steel oil storage tanks of various sizes and capacities for internal pressures not more than 2 1 / 2 pounds per square inch gauge.This standard is meant to be a purchase specication to facilitate the manufacture and procurement of storage tanks for the petroleum industry.
