The LPG spherical tank is a fixed-pressure vessel at normal temperature, with a single-layer tank structure, dedicated to storing liquefied petroleum gas, using low-alloy steel plates for the vessel, with excellent performance, safety and reliability. Spherical storage tanks have a smaller surface area, greater corrosion resistance, and are moisture and corrosion resistant.
Key Features
The main material is made of low-alloy steel plates for containers, and safety accessories can be selected according to different customer needs. International and domestic well-known brands, professional design, manufacturing and installation teams, complete quality assurance system, volume series covering 200m³~10000m³, can be customized according to customer needs.
What is the purpose of the LPG Spherical Tank?
This product is used for large-capacity, pressure-bearing spherical storage vessels.
What benefits will you get from LPG Spherical Tank?
Compared with other storage tanks, the use of lpg spherical tanks can greatly reduce the consumption of steel, generally saving 30% to 45%; in addition, the lpg spherical tank has a smaller area and a small amount of basic engineering.
Where can this LPG Spherical Tank be used?
This product can be used in areas where the ambient temperature is -50℃~50℃, and it can be used in various regions such as Asia, Africa, and South America.

Small surface area
Lpg Spherical Tanks are typically used to store liquids and pressurized gases below ambient temperature, such as ammonia, propylene, LPG, butadiene, and others. Most (or many) spheres operate at low temperatures, with a lower limit of -50°C (-58°F). Gases are stored at pressures below their liquefaction temperature.
The main advantage of the Lpg Spherical Tank construction is that when storing pressurized gases, stress concentrations within the sphere are minimized because the stress resistance is uniform over the entire surface. Another advantage is the reduced outer surface for a given storage volume compared to all other possible shapes.
Due to the high temperatures in cold storage and the often high ambient temperatures and humidity outside the Lpg Spherical Tank, the key requirement is to have a well-designed and installed insulation system to maintain a consistent temperature inside the sphere.
High corrosion resistance
Dimensional stability and compatibility with substrate expansion/contraction.
As the Lpg Spherical Tank is put into service and cooled to operating temperature, the surface of the sphere shrinks and the diameter of the sphere decreases. The insulation system must be designed to accommodate this dimensional change.
Control of permeability and hygroscopicity.
The temperature difference between the object and its surroundings is the cause of surface condensation. This, coupled with moisture entering from the outside by other means, can have a serious adverse effect on the efficiency and safety of the Lpg Spherical Tank.
High safety
Control heat gain.
By preventing heat transfer, you will be able to store content as efficiently as possible by keeping energy requirements and operating costs low.
Risk of chemical absorption.
If a leak or spill occurs, the insulation may also absorb the contents of the Lpg Spherical Tank, which typically contains flammable liquids with low flash points, posing a significant fire and explosion hazard. The use of open cell or fiber insulation systems may have a serious adverse effect on the safety of the Lpg Spherical Tank, resulting in the absorption of flammable liquids and a core-suction hazard, which could result in a spontaneous combustion fire.
