Static Equipment Interview Questions <A-Z FREE>

A wind girder is a stiffening ring attached to the outside of a tall, thin storage tank or stack to prevent buckling due to wind loads (ovalization).

ASME B31.3 (Process Piping) vs. B31.1 (Power Piping).

Indicates the shell type (e.g., E = One-pass shell, F = Two-pass shell with longitudinal baffle).

What are the primary international codes used for designing static equipment? A wind girder is a stiffening ring attached

The Expectation: Understanding thermal stress mitigation. Model Answer: "A bellows expansion joint is a flexible element welded into the shell side of a fixed tubesheet exchanger. It absorbs differential expansion between the shell and the tubes. However, it is a critical weak point : it is thin (usually multi-ply), susceptible to fatigue cracking due to cycling, prone to corrosion under the convolutions, and can 'squirm' (column buckling) if the internal pressure gets too high."

Use HIC-resistant steel (low sulfur, low phosphorus, inclusion-controlled), employ proper PWHT, and apply corrosion-resistant liners or coatings. 5. Inspection & Non-Destructive Testing (NDT) This is inlet erosion/corrosion
