Shell Thickness Design

: Which specific paragraph or section of the ASME code is used to calculate the required thickness of a shell? "Describe a time you found a design discrepancy

"Describe a time you found a design discrepancy in a static equipment drawing. How did you resolve it?"
"A column is being over-pressured during startup. As the site engineer, what do you check first?" (Answer: Relief valve set pressure, blocked outlet, blocked in relief path, or undersized valve)
"How would you justify a change from carbon steel to stainless steel for a vessel?" (Answer: Corrosion rate, safety, product purity, downtime cost, lifecycle cost analysis)

Excellent answer:

(welded steel tanks for oil storage) and API 620 (design and construction of large, low-pressure storage tanks)? Material Selection : What are the specific requirements for NACE materials and equipment used in hydrogen service? Testing & Inspection : Why is it safer to perform a hydrostatic test on a pressure vessel rather than a pneumatic test with gas? Valve Function : What is the primary purpose of a steam trap Excellent answer: (welded steel tanks for oil storage)
