Q

What is the most commonly used material for valve construction in LNG cargo piping?

🔍 Key Concepts

• Cryogenic temperatures of LNG cargo (-162°C / -260°F) and material toughness at low temperature • Difference between tank construction materials and valve/piping materials on LNG carriers • Common industrial practice for valves handling very cold, corrosive media

💭 Think About

• Think about which material is widely used for valves in many different industries where both corrosion resistance and low-temperature toughness are important. • Ask yourself which of these options is more typically associated with cargo tank shells versus machined valve bodies and trim. • Consider what material is commonly used for flange faces, valve bodies, and fittings in cryogenic service, not just for the main cargo tank walls.

✅ Before You Answer

• Verify which material maintains ductility and toughness at LNG temperatures rather than becoming brittle. • Check which option is more commonly used for cargo tank plates (shells) and which is more often used for valves and small fittings. • Confirm which material has widespread corrosion resistance in marine and cargo environments, especially with hydrocarbons.
