The loading and unloading site for liquid ammonia tanks should be prohibited from being set near densely populated areas such as schools, hospitals, and residential areas. The quantity of liquid ammonia stored must meet the national standards or relevant national regulations regarding major hazard sources, and the distance from the following places and areas must comply: 1. densely populated areas such as residential areas, commercial centers, and parks; 2. public facilities such as schools, hospitals, cinemas, and sports stadiums; 3. water sources, waterworks, and protected water source areas; 4. stations, docks (excluding those specially approved and engaged in hazardous chemical loading and unloading according to national regulations), airports, highways, railways, waterways, subway ventilation shafts, and entrances and exits; 5. basic farmland protection areas, pastoral areas, fishing waters, and production bases for seeds, breeding animals, and aquatic seedlings; 6. rivers, lakes, scenic areas, and nature reserves; 7. military restricted areas and military management areas; 8. other areas protected by laws and administrative regulations.

Liquefied ammonia storage tanks, as a type of special pressure vessel, are widely used in the chemical industry for transporting strong acids and alkalis. Over the years, it has been found that these tanks rarely suffer from strength failures, with most damage being caused by corrosion cracks. The corrosion issue with liquid ammonia storage tanks is increasingly being noticed, as many safety concerns arise from their insufficient corrosion resistance. Generally, cracks are more severe in the weld seam areas of the inner surface of the tank, particularly in the hoop welds, and they typically show no plastic deformation, presenting characteristics of brittle cracks. The cracks are usually shallow and elongated with distinct branches, with the main crack perpendicular to the weld seam. This is especially true at the start and end points of manual arc welding, T-joint areas, and where the封头ring weld intersects with the cylindrical longitudinal weld. In addition to strengthening the detection of weld seams, manufacturers of liquid ammonia storage tanks must also improve inventory management of welding rods. It is crucial not to mix welding rods used for different equipment, as this can create hidden quality issues.

　Liquefied Gas Storage TankThe application of these containers is very widespread, and their placement is a critical matter. When placing these containers, many aspects need to be considered. Failure to securely place these chemical storage containers can be highly hazardous, leading to chemical spills and severe corrosion of the containers, causing various issues. When storing chemical items, users must pay attention to the following:

Ensure safe placement; do not affect nearby residents and businesses.Liquefied Gas Storage TankThe location of the storage facility must be carefully selected, undergo risk and quantitative analysis. When placing containers for storing chemical goods, it is imperative that no severe impact is caused to neighboring residents or businesses, and that the daily lives of residents are not affected. The placement of these containers must maintain a certain distance from residential areas to ensure they are not within the impact range. Only then can the containers be properly placed. 2. Ensure compliance with meteorological and geological conditions when placing containers.Liquefied Gas Storage TankIt is mandatory to meet local meteorological requirements, geological conditions, and pay attention to safety issues during thunderstorm seasons, considering whether the area is prone to severe seismic disasters. In placingLiquefied Gas Storage TankAt that time, safety must be the top consideration when storing chemical products. With increasingly limited land resources, ground storage of chemical storage equipment occupies a significant amount of land. Therefore, choosing to store chemical products in underground tanks is an excellent option. Placing tanks underground not only saves on resource utilization but also avoids environmental pollution issues, offering numerous advantages.
