Common deficiencies in pressure vessels during use can include corrosion. Below are some causes that may lead to corrosion in pressure vessels:
- Chemical Media: Certain chemical media are corrosive, such as acids, bases, and salts. When these media come into contact with the vessel material, corrosion may occur.
- Humidity and Moisture: High humidity environments or prolonged exposure to moisture can lead to corrosion on the vessel surface, especially when oxygen is present, which may accelerate the corrosion rate.
- Rusting: When the protective layer on the vessel surface (such as coatings or plating) is damaged or destroyed, the vessel may suffer from rusting. Rusting can damage the surface of the vessel and may lead to further corrosion.
- Electrochemical Corrosion: When different metals or metals and non-metals come into contact, electrochemical corrosion cells may form, which can lead to localized corrosion on the vessel surface.
- Welding Defects: Defects like weld pores and cracks may be introduced during the welding process. These defects can serve as starting points for corrosion.
- Corrosion weakens the structural integrity of the vessel, increasing the risk of leakage or rupture. Therefore, it is important to regularly inspect and maintain the corrosion protection layer, coating, or plating of pressure vessels. If corrosion issues are found, timely measures should be taken to repair or replace the damaged parts.
- Additionally, selecting appropriate materials and corrosion prevention measures, as well as proper operational and maintenance methods, can reduce the risk of corrosion in pressure vessels. Adhering to relevant safety operation procedures and standards ensures the safe operation of pressure vessels.
For accessories of CO2 storage tanks, such as valves, pipelines, and pressure relief devices, maintenance and protection are crucial. Here are some suggestions:
Regular Inspection: Conduct regular checks on the appearance and operational status of accessories to ensure there is no damage, looseness, or leakage. Pay special attention to the sealing performance and operational flexibility of valves.
Cleaning and Maintenance: Regularly clean the accessories, removing dirt and impurities from the surface. Use appropriate cleaning agents and tools, avoiding corrosive substances.
Lubrication Maintenance: For accessories requiring lubrication, such as the pistons and stems of valves, perform regular lubrication maintenance. Use suitable lubricants to ensure the normal operation and sealing performance of valves.
Sealing Inspection: Regularly check the sealing performance of accessories, such as the seals and sealing surfaces of valves. Replace any damaged or aging seals promptly.
Corrosion Protection: For accessories prone to corrosion, such as pipelines and valves, implement corrosion protection measures, such as coating with anti-corrosion paint or wrapping with anti-corrosion materials.
Regular Calibration: Calibrate measuring equipment such as level sensors and pressure sensors regularly to ensure their accuracy and reliability.
Regular Maintenance: Develop a regular maintenance plan based on the usage and requirements of accessories, including cleaning, lubrication, and repairs, to ensure long-term stable operation.
Storage and Transportation Caution: For spare or replacement accessories, pay attention to moisture-proof, shockproof, and damage-proof during storage and transportation to avoid affecting their normal use.
The above suggestions are for the maintenance and protection of CO2 storage tank accessories. Specific operations should be carried out according to the characteristics and requirements of the accessories and in accordance with relevant regulations.

Low-temperature carbon dioxide storage tanks offer several advantages:
- Low-temperature storage capacity: These tanks can store carbon dioxide at low temperatures, typically between -40°C to -70°C. This low-temperature storage allows carbon dioxide to be stored in a liquid state, significantly reducing the storage space required.
- High storage density: Due to the liquid state of carbon dioxide at low temperatures, its storage density is relatively high. Compared to gaseous storage, liquid storage can hold more carbon dioxide in a smaller tank, improving storage efficiency.
- Environmental and renewable: Carbon dioxide is an environmentally friendly gas, and its storage and use do not produce harmful substances. Moreover, carbon dioxide can be reused through capture and recycling technologies, reducing environmental impact.
- High safety: Low-temperature carbon dioxide storage tanks are made from high-strength materials with good sealing and corrosion resistance. They are equipped with safety valves and pressure relief devices to effectively control internal pressure and temperature, ensuring safety during storage.
- Wide application: These tanks are widely used in various fields, such as the food and beverage industry, pharmaceutical industry, and chemical industry. They can be used for frozen food, refrigeration equipment, gas supply, and more, meeting diverse industry needs.
In summary, low-temperature carbon dioxide storage tanks offer advantages such as low-temperature storage capacity, high storage density, environmental friendliness, renewability, high safety, and wide application. These benefits make them crucial storage equipment for carbon dioxide in many industries.
