Horizontal LNG Storage Tank

Product Overview
Horizontal LNG Storage Tank is a double-wall cryogenic pressure vessel designed for the storage and transfer of liquefied natural gas (LNG). It provides long-term low-temperature containment with minimized boil-off loss for industrial, energy, and distribution applications.

Engineering & Design Features
Double-wall vacuum insulated structure minimizes heat ingress and reduces LNG boil-off rate during long-term storage.
Inner vessel manufactured from cryogenic-grade stainless steel ensures reliable performance at temperatures as low as -196°C.
Carbon steel outer shell with vacuum-perlite insulation system provides mechanical protection and thermal efficiency.
Optimized pressure-retention design extends storage duration while reducing product loss and venting frequency.
Integrated safety instrumentation and protection devices support safe operation under cryogenic and pressure service conditions.
