A spherical tank(or sphere vessel) is a high-pressure storage container designed in a sphericalshape to evenly distribute stress and maximize structural integrity, making it ideal for storing liquefied gases (such as LPG, LNG, ammonia, or compressed air). Compared to cylindrical tanks, spheres offer greater volume-to-surface efficiency, reducing material costs while withstanding extreme pressures. They are constructed from high-strength steel with welded seams and often include insulation layers, safety valves, and corrosion-resistant coatings for hazardous media. Common applications include petrochemical plants, gas distribution terminals, and aerospace fuel storage. Advanced designs incorporate real-time pressure monitoring systems and earthquake-resistant supports to ensure safety in critical industrial operations.
