The materials used at different temperatures are different. For example, phenolic foam resin is as high as -196 degrees, polyurethane is usually as low as -60, rubber and plastic -20, glass wool +300, rock wool +600, etc.! So it depends on the nature of the items themselves contained in the stainless steel storage tank! Storage tank classification Due to the different storage media, there are also various forms of storage tanks. Classification by location: It can be divided into above ground storage tanks, underground storage tanks, semi-underground storage tanks, offshore storage tanks, submarine storage tanks, etc. According to oil classification: It can be divided into crude oil storage tanks, fuel storage tanks, lubricating oil tanks, edible oil tanks, fire tanks, etc. 1. Reasons for chemical cleaning During the installation, welding and manufacturing of the storage tank, the inner surface of the steel has dust, welding slag, grease, rust, etc. The presence of these dirt will pollute the product and affect the chemical and physical qualities of the storage medium. Therefore, chemical cleaning must be carried out to meet the required cleanliness. 2. Cleaning method 1. Spray cleaning is a circular cleaning technology. During the cleaning process, the chemical cleaning solution is evenly sprayed on the inner surface of the system to be cleaned, and the gravity of the cleaning liquid flows to the bottom along the container wall to the bottom, so that the cleaning liquid is fully in contact with the rust and dirt on the inner wall of the container, and a chemical reaction occurs to meet the requirements of the cleaning system. By adjusting the position of the spray head, the cleaning liquid can be sprayed to the top of the tank and the tank wall to ensure the cleanliness of the entire inner surface. 2. In spray cleaning, the design of the sprayer is very important. Improper design or selection of the sprinkler will cause the cleaning liquid to be unevenly distributed, which directly affects the cleaning effect. The commonly used sprinkler head is a rotating nozzle. A rotating nozzle is installed on the top of the tower or container to be cleaned, and the nozzle is driven by hydraulic torque to achieve the purpose of rotating the nozzle.
