Do not just memorize code names. Understand why API 650 applies to storage tanks while ASME VIII applies to pressure vessels. Know the specific testing margins (e.g., hydrostatic test pressures are typically 1.3x MAWP for ASME VIII Div 1).
: Explain the difference between design-by-rule (Div. 1) and design-by-analysis (Div. 2).

is based on "Design by Analysis" (allows for higher allowable stresses, requires more detailed stress analysis, and can result in thinner, more cost-effective shells).
is a major industry threat. It occurs when water gets trapped under insulation, creating a corrosive environment on the hot metal surface. Do not just memorize code names
Static equipment forms the backbone of the oil and gas, petrochemical, and power generation industries. Unlike rotary equipment, these components do not have moving parts, but they operate under extreme pressures, temperatures, and corrosive environments.
Key points: thermal expansion, differential expansion, tube-to-tube sheet joint types, tube vibration (fluid/flow-induced), fouling factors in thermal design. Follow-up: Explain how you would handle different thermal expansion rates between shell and tubes. : Explain the difference between design-by-rule (Div
Q10: What is the standard Hydrostatic Test pressure for an ASME Section VIII Div. 1 vessel?
Affects Austenitic Stainless Steels (300 series) at temperatures typically above 60°C in the presence of moisture and chlorides.
