Cryogenic Liquid Oxygen Storage Tanks: Ensuring Safe and Efficient Oxygen Supply
Introduction:
Cryogenic liquid oxygen storage tanks are essential equipment for various industries that rely on a stable and high-purity oxygen supply. These specialized tanks are designed to safely store liquid oxygen at extremely low temperatures, ensuring minimal losses due to evaporation. This description explores the design, features, applications, and manufacturing process of these crucial tanks, with a focus on their advantages and specifications. We'll also touch upon specific customer feedback to showcase the practical uses of these units.
Construction and Design:
Our liquid oxygen storage tanks are built with a robust double-walled cylindrical structure. The inner cylinder and piping are meticulously crafted from high-grade stainless steel (S30408), chosen for its exceptional strength and resistance to cryogenic temperatures. The outer shell is made from durable alloy steel (Q245R), providing further structural integrity and protection.
The annular space between the inner and outer walls is filled with expanded perlite (perlite sand), a highly effective insulation material. This space is also treated with a specialized adsorbent material. A high vacuum (0.5 to 6 Pa) is created within this area, ensuring optimal thermal insulation, minimizing heat transfer, and reducing boil-off. These tanks are available in capacities of 200 m³ or less, catering to diverse industrial needs.
With high operating pressures (2.0 MPa for two tanks in four workshops) and external vaporizers, these tanks are easy to fill and allow for the direct supply of pressurized gas. Designed for both stationary and transport applications, the tanks can be tailored to specific requirements.
Types and Applications:
Stationary Tanks: Primarily used for long-term storage of cryogenic liquids at production sites, utilization points, or cryogenic liquid supply stations.
Transportable Tanks: These tanks are engineered for transporting low-temperature fluids. They come in the form of road tankers, trailers, and ship tankers, facilitating the transfer of cryogenic liquids between production and usage locations. They are available in vertical (L) and horizontal (W) orientations for placement flexibility.
Customer Feedback Highlight:
A recent inquiry from a hospital in Brunei indicates the practical use for these tanks. They needed a five-cubic-meter cryogenic oxygen storage tank to address their medical needs, underscoring the importance of reliable and compact oxygen storage solutions in healthcare settings.

Applications Across Industries:
Metallurgy: In steel production, high-purity oxygen is used to react with carbon, phosphorus, sulfur, and silicon. This reduces carbon content, eliminates impurities, and enhances the quality of steel. It also helps maintain necessary high temperature in the smelting process. Oxygen enrichment can also shorten smelting time and increase metal output in non-ferrous metal production and blast furnaces.
Chemical Industry: Oxygen plays a vital role in the production of synthetic ammonia by oxidizing raw materials. This improves processes such as thermal cracking of heavy oil and coal dust gasification and increases fertilizer output.
Defense: Liquid oxygen is a crucial oxidizer in modern rockets and supersonic aircraft. It is also used to produce liquid oxygen explosives by creating highly explosive reactions when mixed with flammable materials.
Medical: Oxygen supply is essential for various medical applications including treating hypoxia, supporting patients in surgeries, and facilitating work in high-altitude, diving, and aerospace environments.
Manufacturing Process Overview:
Our rigorous manufacturing process ensures the highest quality and reliability.
Volume Calculation & Blueprint Development: Defining the dimensions and creating the initial design.
Material Preparation & Cutting: Sourcing and preparing raw materials.
Steel Rolling: Rolling steel plates to required shapes.
Steel Plate Welding: Joining steel components.
Storage Tank Assembly: Assembling main components of the tank.
Insulation Filling: Filling the space between the inner and outer shells with insulation material.
Vacuum Creation: Creating a high vacuum within the insulation layer.
RT, MT & X-Ray Inspections: Conducting rigorous inspections for weld integrity.
Rust Removal: Preparing surface for painting.
Valve Installation: Fitting all valves and control system components.
Enhanced Features:
Adiabatic Performance: Our tanks incorporate perlite sand insulation combined with a vacuum environment and a precise filling process. This leads to superior adiabatic performance, reducing thermal leakage and minimizing evaporation. A surface anti-corrosion process with sandblasting, rust removal, and two-component fast-curing liquid coatings ensures longevity.
Robust Safety: These tanks employ a 'combination safety system' with two sets of safety valves, ensuring safe operations even during regular maintenance and checks.
Advanced Control System: The pressure gauge, differential level gauge, and level comparison table provide real-time monitoring, helping operators maintain pressure and inventory levels during filling and emptying processes.
Integrated Monitoring: Vacuum measuring devices and valves at the bottom of the tank allow for periodic checks and ensure consistent vacuum level, crucial for maintaining safety and efficiency.
