Routine inspections and maintenance of liquid oxygen tanks are crucial for ensuring their safe operation. The following are general steps for the daily checks and maintenance of liquid oxygen tanks:
Appearance Inspection: Regularly inspect the tank's exterior, including the shell, welds, valves, and fittings. Pay attention to any signs of cracks, corrosion, or deformation.
Leak Detection: Utilize suitable leak detection equipment to inspect for leaks in tanks and connections. Leak detection methods such as gas detectors or liquid oxygen probes can be employed.
Pressure Testing: Conduct regular pressure tests to check the tank's sealing and pressure resistance. Perform pressure tests according to relevant standards and specifications, and record the test results.
Valve and fitting inspection: Verify that the tank's valves and fittings are operating correctly and for any signs of looseness or damage. Ensure the valves are responsive and reliable in their operation.
Insulation Layer Inspection: Check for any damage or detachment in the tank's insulation layer. Repair or replace any damaged insulation materials to ensure effective insulation.
Cleaning and Drainage: Regularly clean the interior of the tank to remove accumulated impurities and dirt. Regularly drain to prevent contaminants and sediments in liquid oxygen from damaging the tank.
Safety Equipment Inspection: Examine the safety equipment around the storage tanks, such as fire isolation zones and alarm systems, to ensure they are functioning properly.
Record and Document Management: Document the results of each inspection and maintenance, including the inspection date, contents, issues found, and corrective measures. Establish comprehensive management records and documents for tracking and managing the tank's operational status.
Note that inspections and maintenance of liquid oxygen tanks should be conducted by trained personnel and in accordance with relevant regulations and standards. Ensure safety during maintenance and operations, and consult with experts for accurate guidance.

The dimensions and structure of liquid oxygen storage tanks can vary based on specific requirements and applications. The following are common sizes and structures of liquid oxygen storage tanks:
Dimensions: The size of liquid oxygen tanks is typically determined by the capacity for storage or transportation. Common capacities range from a few thousand to several tens of thousands of liters.
Structure: The structure of the liquid oxygen storage tank mainly includes the inner shell, outer shell, insulation layer, and supporting structure, etc.
The inner shell of a liquid oxygen tank is the part designed for storing liquid oxygen, typically made from materials such as stainless steel or aluminum alloys, which offer excellent corrosion resistance and sealing properties.
Shell: The shell of a liquid oxygen tank is the external structure that protects the inner lining, commonly made of carbon steel or stainless steel, featuring sufficient strength and corrosion resistance.
Insulation Layer: The insulation layer of liquid oxygen tanks is used to reduce heat conduction and loss, maintaining the low-temperature state of liquid oxygen. Common insulation materials include polyethylene foam, glass fiber, and aerogel, etc.
Support Structure: The support structure for the liquid oxygen tank is designed to support and secure the inner and outer shells of the tank. Typically made of steel, the support structure boasts adequate strength and stability.
The dimensions and structural design of liquid oxygen tanks must consider the properties of liquid oxygen, storage or transportation requirements, safety standards, and other factors. When using liquid oxygen tanks, it is crucial to strictly adhere to relevant operational specifications and safety requirements to ensure safe usage.

Routine inspections for liquid nitrogen tanks primarily include the following aspects:
Visual Inspection: Check for any obvious damage, deformation, or corrosion on the tank's exterior, including the tank walls, valves, pipes, and joints.
Sealability Inspection: Verify the sealing performance of the storage tank, including checking for any leaks at valves and pipe connections, as well as ensuring the exhaust valve and safety valve of the tank are functioning properly.
Pressure Check: Verify that the tank's pressure gauge is functioning properly and that the pressure is within the normal range to ensure the tank operates correctly.
Level Check: Inspect the liquid nitrogen tank's level to ensure it remains within the normal range, avoiding issues caused by levels that are too high or too low.
Insulation Layer Inspection: Check for any damage or detachment in the storage tank's insulation layer to ensure its effectiveness and reduce the evaporation loss of liquid nitrogen.
Leak Inspection: Check for signs of liquid nitrogen leakage around the storage tank, including frost, ice, or liquid nitrogen residue on the ground.
Safety Equipment Inspection: Check that the storage tank's safety equipment, such as leak detectors, alarm systems, and safety valves, are functioning properly to ensure the tank's safety.
Cleaning Inspection: Regularly clean the interior of the tank to remove accumulated impurities and dirt, maintaining the tank's cleanliness and hygiene.
Above are the key items for daily inspection of liquid nitrogen tanks. The specific inspection content should be adjusted and supplemented according to the tank's model, usage, and relevant regulations. During the inspection process, strict adherence to the relevant operational procedures and safety requirements is essential to ensure the safe operation of the tank.
