The Expectation: Understanding of pressure thresholds (often 15 psi) and design standards. Model Answer: "The general rule of thumb is that a 'vessel' operates above 15 psig (internal or external), while a 'tank' operates at atmospheric pressure or slightly above (typically less than 2.5 psig). Vessels are designed to ASME Section VIII, while tanks are designed to API 650 (large welded storage) or API 620 (low-pressure)."
Galling is a severe form of adhesive wear that occurs when stainless steel or aluminum bolts are tightened. The oxide layer shears off, allowing bare metal-to-metal contact. Friction generates heat, welding microscopic high spots. The bolt seizes and shears off. Prevention: Use anti-seize lubricant (Nickel-based for high temp, Copper-based for normal), or use coated studs (PTFE or Xylan). The oxide layer shears off, allowing bare metal-to-metal
