For tanks coated with corrosion-resistant paint, regularly inspect the coating's condition and perform repairs or recoating to protect the tank from corrosion. Leak Detection: Regularly perform leak detection to ensure there are no leakage issues. Use gas detectors or leak detectors for testing, or evaluate the tank's sealing performance through pressure tests. Safety Valve Inspection: Regularly check and test the functionality of safety valves to ensure they operate normally under overpressure conditions. Adjust and test according to the specifications and requirements of the safety valves. Pipe and Valve Maintenance: Regularly inspect and maintain the pipes and valves connected to the tank to ensure their proper operation and sealing performance. Clean and lubricate valves, and check for leaks at pipe connections. Documentation: Record the dates, contents, and results of maintenance, establishing a maintenance record for the tank. Retain relevant documents and reports for future reference and review. Please note that for the maintenance of CO2 storage tanks, it is recommended to follow relevant safety operating procedures and standards. If you do not possess the necessary knowledge and experience, it is advisable to consult personnel or manufacturers for maintenance work.

Low Temperature Carbon Dioxide Storage Tank Related Knowledge 1. Structure of Low Temperature Carbon Dioxide Storage Tank The low temperature carbon dioxide storage tank typically features a double-layered cylindrical structure. The inner cylinder is made of 6MnDR alloy steel, while the outer cylinder is constructed from Q245R or Q345R pressure vessel steel plate. The piping is made of austenitic stainless steel, and the insulation layer is filled with high-vacuum sintered sand or wrapped with multiple layers for thermal insulation. The storage tank is equipped with valves for operation, which are arranged for ease of use. It also includes a pressure gauge and a level gauge for monitoring the pressure and liquid level inside the tank. 2. Key Features of Low Temperature Carbon Dioxide Storage Tank (1) The tank is fitted with a liquid filling connection for trucks, allowing supply to vaporizers, tank trucks, and pumps. (2) Both the inner and outer cylinders are equipped with safety devices to ensure safe operation for the user. (3) The insulation material of the low temperature carbon dioxide storage tank is specially treated to provide a longer vacuum life. Additionally, the tank is equipped with a vacuum gauge for measuring the vacuum level of the insulation layer as needed. 3. Transportation of Low Temperature Carbon Dioxide Storage Tank (1) During road transportation, the tank should be securely fastened to the vehicle, travel at moderate speeds, and avoid collisions with other objects. (2) After arrival, the unloading personnel should work with the equipment supervisor to develop a scientific and reasonable unloading plan. 4. Installation of Low Temperature Carbon Dioxide Storage Tank (1) Upon arrival at the installation site, the tank can be positioned when installation conditions are met. During the installation process, avoid impacts and strikes, and pay special attention to the explosion-proof equipment on the outer cylinder and the vacuum valve, which should not be touched. (2) Perform a gas-tightness test on the inner cylinder system using nitrogen to the working pressure. After checking that valves, pipes, flanges, etc., are leak-free, the installation is complete. (3) The installation dimensions are as specified in the supply materials. When considering liquid filling and emptying with tank trucks, account for the vehicle's travel path.

When planning carbon dioxide storage tanks, the following requirements should be considered: - Safety Distance: Tanks should maintain adequate distance from surrounding buildings, equipment, and personnel to prevent injuries and losses in case of accidental incidents. Specific safety distance requirements may be stipulated by local regulations and standards. - Tank Capacity: Determine the tank's capacity based on actual needs and usage. The capacity selection should consider factors such as the amount of CO2 used, storage cycle, and supply demand. - Tank Layout: The layout should facilitate operation and maintenance while meeting safety and environmental protection requirements. There should be sufficient spacing between tanks for ease of operation and maintenance. - Tank Material: Select appropriate materials for manufacturing the tank to ensure corrosion and pressure resistance. Common materials include carbon steel, stainless steel, etc. - Safety Equipment: Tanks should be equipped with necessary safety equipment, such as safety valves, pressure sensors, temperature sensors, etc., to ensure safe operation. - Leak Protection: Measures should be taken to prevent CO2 leaks, such as sealed valves, leak detection systems, etc. Appropriate leak handling procedures and emergency response plans should also be in place. - Environmental Impact Assessment: An environmental impact assessment should be conducted when planning the tanks to evaluate their impact on the surrounding environment and implement corresponding measures for environmental protection. - Regulations and Standards: Adhere to local regulations and standards when planning tanks, including building codes, safety regulations, environmental protection requirements, etc. It is important to note that planning carbon dioxide storage tanks should be carried out by engineers or relevant agencies to ensure compliance with safety and environmental protection requirements. Consulting with local authorities for advice and guidance is also necessary.

Before using a carbon dioxide tank, the following preparatory steps are required: Safety Inspection: Conduct a thorough safety check of the tank before use to ensure there are no obvious damages, corrosion, or leaks. Inspect the tank's exterior, valves, and connecting pipes to ensure they are intact and undamaged. Tank Cleaning: Ensure the tank is clean both internally and externally. Remove any debris, dirt, and residues inside the tank to ensure no substances could potentially affect the quality or safety of the carbon dioxide. Connecting Pipes: Check the connection between the tank and associated pipes to ensure they are securely fastened and sealed properly. Verify the opening and closing status of valves and pipes to ensure they are in the correct position. Pressure Check: Inspect the tank's pressure to ensure it is within the safe range. If necessary, use a pressure gauge or other pressure detection equipment for the check. Ventilation and Safety Measures: Ensure adequate ventilation around the tank to prevent the accumulation of carbon dioxide. During operation, follow relevant safety procedures and measures, such as wearing personal protective equipment and avoiding open flames. Tank Labeling: Label the tank with relevant information, such as the type of gas stored, pressure rating, and capacity. This assists operators in correctly identifying and handling the tank. Please note that these preparatory steps may vary depending on the specific type of tank and usage scenario. Before using a carbon dioxide tank, it is recommended to refer to the relevant safety operation manuals and guidelines to ensure safe and correct operation.
