Buffer Tank - Basic, Concept, Design, Calculation, 3D Model Explanation

A: This achieves code compliance by tying classification to maximum possible internal pressure, not normal operation. B fails because ASME doesn’t trigger on volume alone. C misunderstands system boundaries; relief location doesn’t declassify the vessel. D mixes up stored energy theory with how ASME defines a pressure vessel.

A: This protects the tank by addressing the highest corrosion rate mechanism present in that environment. B is slow in closed loops with inhibitors. C needs much higher chloride activity than HVAC glycol provides. D is possible but secondary compared to wet-dry external exposure.

A: This impacts thermal performance by allowing flow to bypass the stored volume. B is unrelated to nozzle elevation. C confuses system pressure profile with tank internals. D depends on top connections, not side nozzle elevations.

A: This stabilizes control by slowing temperature change relative to load variation. B is a side benefit at best. C misreads pump hydraulics. D confuses buffer tanks with expansion vessels.
