Large tanks with hemispherical heads on both ends are used for which type of material?

Explanation:
Hemispherical ends are used because they distribute internal pressure evenly and minimize stress concentrations at the junction with the shell. This geometry handles high internal pressures with a given wall thickness much better than flat or sharp-edged ends, making it the strongest and most reliable choice for high-pressure service. Other types of storage emphasize insulation for cryogenic liquids, corrosion-resistant materials for corrosive liquids, or practical shapes for bulk handling, rather than the stress management that hemispherical heads provide. So the best fit is high pressure.
