How do you determine the required wall thickness for a cylindrical shell?
Thickness is calculated based on design pressure, internal diameter, allowable stress of the material at design temperature, and joint efficiency, with an added corrosion allowance. 2. Heat Exchangers (TEMA & API) Why is an expansion bellow used in some heat exchangers? static equipment interview questions
Static equipment engineering is a discipline of . The codes (ASME, API, TEMA) are not just rules—they are the collective lessons learned from past explosions and failures. How do you determine the required wall thickness
Uses a "Design-by-Rule" approach. It features higher safety factors (typically 3.5), resulting in thicker walls. It requires less complex calculations and is cheaper for standard pressure applications. Heat Exchangers (TEMA & API) Why is an
MDMT stands for Minimum Design Metal Temperature. It is the lowest temperature at which a pressure vessel can safely operate under full design pressure. Knowing the MDMT is critical to prevent brittle fracture, a catastrophic failure mode that occurs without warning when metals become brittle at cold temperatures. Designers use impact testing to verify material toughness at the MDMT.
