What is the most commonly used material for valve construction in LNG cargo piping?
AI Explanation
The correct answer is D) Stainless steel.
Stainless steel is the most commonly used material for valve construction in LNG cargo piping systems. This is because stainless steel is highly resistant to corrosion and can withstand the extremely low temperatures associated with the handling and transport of liquefied natural gas (LNG). The other answer choices, such as nickel alloy steels and aluminum, are not as suitable for LNG service due to their decreased resistance to the cryogenic temperatures or increased susceptibility to corrosion.
