Suitable Services
LNG terminals and LNG storage tank valves
LPG and propane storage and transfer
Ethylene and propylene plants
Cryogenic air separation units (ASU)
Cold-climate oil and gas pipelines (Alaska, Siberia, Northern Canada, Norway)
CO₂ sequestration and cold CO₂ gas service
Not Suitable For
Temperatures below −46°C — use A352 LCB (to −60°C) or SS316 for colder service
Strong acids or corrosive fluids — carbon steel has no inherent corrosion resistance
H₂S service — requires NACE MR0175 hardness control
Valve Body Applications
Gate valve bodies for cryogenic and low-temperature service
Ball valve bodies for LNG terminal isolation valves
Globe valve bodies for LPG, propane, and refrigeration service
Check valve bodies for cold-weather pipeline installations
Trim Applications
LCC trim not recommended — trim is typically SS316 or 13Cr with Stellite overlay
Typical Valve Types in ASTM A352 Grade LCC
Gate valves: ASME Class 150–1500, low-temperature service
Ball valves: LNG isolation service, ASME Class 150–900
Globe valves: LPG and refrigerant service
