Understanding Dalian Stainless Steel Spherical Tanks in One Article: Structure, Advantages, and Core Application Scenarios

Stainless steel spherical tanks have become the backbone of industrial storage due to their unique spherical structure and excellent performance. From structural design to application scenarios, every detail of it embodies engineering wisdom and technological innovation.

Structural design is the cornerstone of the performance of stainless steel spherical tanks. It adopts a fully welded hollow spherical structure, which is composed of multiple flaps such as upper and lower polar bands and equatorial bands. This spherical design ensures that the tank body is uniformly stressed. According to the principles of mechanics, pressure can be dispersed along the tangent direction of the spherical surface. Compared with cylindrical tanks, spherical tanks can withstand higher internal pressure. At the same time, the tank is equipped with accessories such as manholes, connecting pipes, level gauges, safety valves, etc., to ensure the safety and convenience of medium storage and transportation. Some large spherical tanks also adopt a double-layer structure, with insulation materials filled in the middle to further enhance their thermal insulation performance.

 

The performance advantage makes Dalian stainless steel spherical tanks stand out. In terms of corrosion resistance, it is made of austenitic stainless steel materials such as 304 and 316. The passivation film formed by chromium element can resist the corrosion of acid, alkali, salt spray and other media, making it suitable for storing highly corrosive chemicals; The high-strength characteristics enable it to withstand high temperature and high pressure environments. After special heat treatment processes, the yield strength of the tank can reach over 300MPa; In addition, the spherical tank has a small footprint and high space utilization rate. Under the same volume, the surface area of the sphere is reduced by about 20% compared to the cylinder, which can reduce manufacturing costs and material losses.

The core application scenarios have validated the value of stainless steel spherical tanks. In the chemical industry, it is used to store hazardous chemicals such as liquid ammonia and sulfuric acid to ensure production continuity; In the energy sector, liquefied natural gas (LNG) and liquefied petroleum gas (LPG) are efficiently stored and transferred through spherical tanks; The food and pharmaceutical industry utilizes its pollution-free and easy to clean characteristics to store beverage raw materials and medicinal solvents. From high-risk media to everyday products, stainless steel spherical tanks continue to empower industrial development with their reliable performance.
