Among construction materials utilized in pressure vessels, which one is the most expensive ?
Show answer Hide answer
Answer: C. Titanium
Explanation
Titanium is an expensive specialty corrosion resistant metal utilized in extreme chemical processing environments. The material cost and difficult fabrication requirements make titanium significantly costlier than standard structural alloys. Pressure vessels built from titanium command the highest market prices among common industrial construction materials. Pressure vessels must withstand high internal pressures and corrosive chemical reactions without structural failure. Low alloy steels and high alloy steels offer good strength but lack the extreme corrosion resistance of titanium. Lead is heavy and soft with limited structural strength restricting its use to specialized chemical linings.
Low alloy steel is relatively inexpensive and widely used for standard industrial pressure vessel construction. Lead is an inexpensive heavy metal used for radiation shielding or acid tank linings rather than high pressure shells. High alloy steel is more costly than carbon steel but significantly cheaper than pure titanium.
