14. What are the key considerations for "Green" or sustainable design in static equipment?
: Why is an expansion bellow required in some heat exchanger designs? Additionally, explain the function of the floating head in shell and tube exchangers (it primarily allows for thermal expansion).
You don’t PWHT every weld — only when thickness, material, or service (e.g., wet H₂S, caustic) requires it per ASME VIII, UCS-56 or UCS-68.
Simple, cost-effective, but cannot handle high differential thermal expansion.
RBI is a methodology that determines the inspection frequency and techniques based on the risk (probability
Here’s a curated look at interesting static equipment questions, along with the hidden engineering judgment behind them.
: What are the code requirements for inspection openings , and how do you manually determine the size for a used vessel? Industry & Professional Scenarios
What is the difference between a 2:1 Ellipsoidal head and a Torispherical head?
uses a design-by-rule approach. It relies on conservative, simplified formulas and a higher factor of safety (typically 3.5). It requires less detailed stress analysis.
