Liquefied Natural Gas (LNG) plays a critical role in the global energy landscape, enabling efficient transportation and storage of natural gas across vast distances. Stored at extremely low temperatures around -162°C, LNG reduces natural gas volume significantly, making bulk transport viable. Managing these extreme cryogenic conditions for large volumes of highly flammable substances demands specialized, robust, and exceptionally safe storage infrastructure.
Shijiazhuang Zhengzhong Technology Co., Ltd, globally recognized as Center Enamel, stands as a leader in providing state-of-the-art storage solutions designed for the exacting requirements of large-scale LNG containment. With over three decades of pioneering liquid and gas storage technologies, Center Enamel has become a trusted partner for industries worldwide.
Large-Scale Welded Steel Tanks for LNG
Large-scale welded steel tanks designed for LNG are among the most complex and critical storage vessels in the energy sector. These colossal structures feature double-walled construction with an inner tank made from specialized cryogenic steels that withstand extreme cold without becoming brittle, and an outer carbon steel shell. The annular space between tanks contains high-performance insulation to minimize heat ingress and boil-off gas generation.
Key Advantages for LNG Storage
Extreme Cryogenic Resilience
Welded steel tanks utilize specialized cryogenic steel alloys that retain ductility and strength at -162°C, ensuring structural integrity and thermal performance in extreme cold conditions.
Welded steel construction provides inherent strength and rigidity to safely support immense loads, resisting internal pressures and external forces.
Optimized Boil-Off Gas Management
Tanks integrate seamlessly with sophisticated boil-off gas recovery systems, minimizing product loss and enhancing operational efficiency.
Comprehensive Safety & Monitoring
Engineered to accommodate advanced pressure relief valves, emergency vents, leak detection systems, and integrated monitoring equipment.
Exceptional Durability & Longevity
Welded steel construction ensures service life spanning decades with minimal maintenance requirements and maximum operational uptime.
