For accessories of carbon dioxide storage tanks, such as valves, pipes, and pressure relief devices, maintenance and protection are crucial. Here are some suggestions: Regular Inspections: Conduct regular checks on the appearance and operational status of the accessories to ensure there are no damages, loose parts, or leaks. Pay special attention to the sealing performance and operational flexibility of valves. Cleaning and Maintenance: Regularly clean the accessories to remove dirt and impurities on 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 the accessories, such as the seals and sealing surfaces of valves. Replace any damaged or aged sealing parts promptly. Corrosion Protection: For accessories prone to corrosion, such as pipes and valves, take anti-corrosion 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 the accessories, including cleaning, lubrication, and inspections, to ensure long-term stable operation. Storage and Transportation Precautions: For spare parts or accessories that require replacement, pay attention to moisture-proof, shock-proof, and damage-proof during storage and transportation to avoid affecting their normal use. The above suggestions are for the maintenance and protection of carbon dioxide storage tank accessories. Specific operations should be based on the characteristics and requirements of the accessories and comply with relevant regulations.

The spacing regulations for carbon dioxide storage tanks are typically governed by relevant safety codes and standards, with specific spacing requirements potentially varying due to factors like location, use, and tank capacity. Here are some common spacing rules: - Small spacing between tanks: Generally, the small spacing between adjacent tanks should comply with relevant safety codes and standards. This space ensures that neighboring tanks are not affected in case of a leak or accident. - Spacing between tanks and buildings: The distance between tanks and buildings also needs to meet the requirements of relevant codes and standards. This distance ensures that buildings are not affected in case of a tank leak or accident. - Spacing between tanks and equipment: The spacing between tanks and other equipment (such as pipelines, pumps, etc.) should also comply with relevant codes and standards. This ensures the proper operation and maintenance of the equipment. - Safety and evacuation routes: Adequate safety and evacuation routes should be provided around and between tanks for safe evacuation during emergencies. It's important to note that specific spacing rules may vary by region and industry. Therefore, when installing and using carbon dioxide storage tanks, it is essential to refer to local safety codes and standards and consult with experts to ensure compliance with requirements.
