The use and operation of the liquid oxygen storage tank system should be mindful of the following points:
Safe Operation: When operating the liquid oxygen storage system, it is mandatory to follow the relevant safety operating procedures and standards to ensure the safety of the operators.
Tank Selection: Choose liquid oxygen tanks that meet specifications and standards, ensuring their quality and safety performance.
Tank Installation: Tanks should be installed on a sturdy foundation to ensure stability. Additionally, the area around the tank should maintain good ventilation and be kept away from flammable materials and heat sources.
Seal Integrity Inspection: Regularly check the sealing performance of the storage system to ensure there are no leakage issues at valve and pipe connections.
Pressure Control: The storage tank system should be equipped with a pressure gauge and a safety valve, with regular inspections and maintenance to ensure pressure remains within a safe range.
Fire Prevention Measures: Liquid oxygen has a high oxygen content, which is prone to cause fires. Set up fire walls around the storage tank system, ban smoking and open flames, and ensure safety.
Static protection: During the operation of the liquid oxygen system, static electricity may cause sparks, increasing the risk of fire. Measures such as using static-conductive materials and anti-static equipment should be taken to reduce the accumulation and release of static electricity.
Regular inspections and maintenance: Conduct regular checks on the tank system and related equipment, including valves, pipelines, pressure gauges, etc. Ensure that the equipment is in perfect condition without any damage, and promptly repair or replace any damaged parts.
Waste Gas Treatment: During the operation of the liquid oxygen system, waste gas is produced, and appropriate waste gas treatment measures must be taken to minimize environmental impact.
Above are the precautions to be taken when using the liquid oxygen storage tank system, ensuring operational safety and the normal operation of the system. During operation, strictly follow the relevant operational procedures and safety operation requirements to avoid accidents.

Safe placement of liquid oxygen tanks is a crucial measure to ensure that no danger is posed to the surrounding environment and personnel during use. The following are the safety requirements for the placement of liquid oxygen tanks:
Safety Distance: Liquid oxygen storage tanks should maintain a certain distance from other buildings and equipment. This is to ensure effective control and minimize the impact on the surrounding environment in the event of a leak or fire.
Fire and Explosion Prevention Measures: Liquid oxygen tanks should be placed in a fire-resistant area, away from open flames, high-temperature sources, and flammable materials. The surrounding area should be equipped with fire and explosion prevention facilities, such as fire extinguishers and foam sprinkler systems, to address potential fire risks.
The liquid oxygen tank should be placed on a sturdy, flat foundation to ensure stability. The bottom of the tank should make full contact with the ground to prevent tilting or rocking.
Ventilation Requirements: Liquid oxygen tanks should be placed in a well-ventilated area to ensure normal circulation of gas emissions and oxygen supply. There should be no obstructions around the tank that hinder gas flow.
Identification and Warnings: Oxygen liquid storage tanks must be clearly marked with information such as the stored medium, capacity, and pressure. Warning signs and safety alerts should be placed in the surrounding area to remind personnel of the presence and potential hazards of the oxygen liquid storage tank.
Regular inspections and maintenance: Liquid oxygen storage tanks should be regularly inspected and maintained, including checking the tank's appearance, sealing, and corrosion prevention measures. Any issues found should be promptly repaired or replaced to ensure proper operation and safety.
Be mindful that the safety requirements for the placement of liquid oxygen tanks may vary depending on different regions and industries. When positioning a liquid oxygen tank, adhere to relevant regulations, standards, and safety procedures, and establish appropriate safety measures based on the actual situation. If you are unfamiliar with or have doubts about the safety placement requirements, it is recommended to consult with experts or relevant institutions.

Safe operation and transportation of liquid oxygen storage tanks should pay attention to the following points:
Safe Application Procedures:
Tank Selection: Choose liquid oxygen tanks that meet specifications and standards, ensuring their quality and safety performance.
Tank Installation: Tanks should be installed on a sturdy foundation to ensure stability. Additionally, the area around the tank should be well-ventilated and kept away from flammable materials and heat sources.
Sealability Inspection: Regularly check the sealing performance of the storage tank to ensure there are no leaks at valve and pipeline connections.
Pressure Control: Tanks should be equipped with pressure gauges and safety valves, with regular inspections and maintenance to ensure pressure remains within safe limits.
Fire Prevention Measures: Liquid oxygen has a high oxygen content and is highly flammable. Establish fire walls around the storage tanks, prohibit smoking and open flames, and ensure safety.
Static protection: During the transportation and use of liquid oxygen, static electricity may cause sparks, increasing the risk of fire. Measures such as using static-conductive materials and anti-static equipment should be taken to reduce the accumulation and release of static electricity.
Shipping Precautions:
Transportation Tool Selection: Choose vehicles that meet the requirements for liquid oxygen transportation, ensuring their safety and sealing integrity.
Loading and Unloading: During the transportation of liquid oxygen, appropriate loading and unloading procedures should be adopted.

Low-temperature liquid storage tanks are equipment used for storing low-temperature liquids, commonly employed for storing liquid oxygen, liquid nitrogen, liquid argon, and other low-temperature liquids. These liquids are in a gaseous state at room temperature but are cooled to a liquid state at low temperatures for more efficient storage and use. Low-temperature liquid storage tanks are typically made of high-strength materials such as stainless steel or aluminum alloy to withstand the demands of low temperatures and high pressures. The interiors usually have an insulating layer to reduce evaporation and maintain the low-temperature state. Applications of low-temperature liquid storage tanks include but are not limited to the following areas: They are widely used in rocket engines and propulsion systems, such as liquid oxygen, liquid nitrogen, and liquid hydrogen storage tanks. They store and supply low-temperature liquids as fuel and oxidizers to propel the engines and maintain operation. Industrial Production: Low-temperature liquid storage tanks are used in industrial production for storing and supplying low-temperature liquids like liquid oxygen, liquid nitrogen, and liquid argon. These liquids serve as coolants, raw materials for gas separation, and reactants in chemical reactions. Medical Applications: These tanks are used in the medical field for storing and supplying liquid oxygen to provide oxygen therapy, oxygen inhalation, and operating room applications. Laboratory Research: In scientific research and laboratories, low-temperature liquid storage tanks are used to provide low-temperature liquids as coolants and cryogenic media. They are used for cooling laboratory equipment, material research, superconductivity, and low-temperature physics. In summary, low-temperature liquid storage tanks are extensively applied in aerospace, industrial production, and laboratory research for storing and supplying low-temperature liquids to meet the needs of various fields.
