9. How do you choose the position of a saddle support on a horizontal pressure vessel?

is identified by Nominal Pipe Size (NPS) and Schedule (wall thickness). It is primarily used to transport fluids and gases.

3. What is Joint Efficiency (E) and how does it impact vessel design? static equipment interview questions

The American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code (BPVC) is the global standard. The most critical sections include:

Be prepared to discuss how specific environments (like chlorides for stainless steel) cause brittle failure in ductile materials. How do you choose a NDT (Non-Destructive Testing) method? Visual (VT): Surface defects.

| Feature | Pressure Vessel | Storage Tank | |---------|----------------|---------------| | Pressure | >15 psig (ASME Section VIII) | Atmospheric to <15 psig (API 650/620) | | Shape | Cylindrical/spherical with dished ends | Flat bottom, cone/umbrella roof | | Code | ASME Sec. VIII Div. 1 or 2 | API 650/653, API 620 | | Design focus | Internal/external pressure + cyclic loading | Hydrostatic + wind/seismic | This public link is valid for 7 days

They are checking your knowledge of brittle fracture . The Answer: MDMT is the lowest temperature at which the vessel’s material can safely withstand the applied stress without fracturing. Below the MDMT, carbon steel transitions from ductile to brittle. You manage this via:

A tubesheet is a perforated plate that holds the tubes in place and separates shell side from tube side fluid. Key considerations:

Fugitive emissions are unintentional leaks of gases/vapors from pressurized equipment (valves, flanges, pump seals). Static equipment contributes via: Can’t copy the link right now
