Stainless steel carbon steel storage tanks are the main measures in petroleum storage and transportation. During the process of unloading, transportation and laying, it should be smooth and gentle to avoid vibration of the stainless steel storage tank, which may cause the cement mortar lining to loosen or even fall off. The low-pressure water supply system needs to rely on external firefighting forces and completely relies on fire trucks for pressurization. The system takes a long time to start up and cannot meet the firefighting needs of the storage tank area. Aqueous film-forming foam fire extinguishing agent is a highly efficient fire extinguishing agent. It has the characteristics of low surface tension, good foam sealing, good fluidity, liquid spraying mode, and can be used in combination with dry powder. Compared with other foam liquids, it has a longer validity period and can be used with priority.
       Maintenance and overhaul of stainless steel and carbon steel storage tanks In order to ensure the safe production of enterprises and the safe operation of equipment, and improve the service life and labor productivity of equipment, regular inspection and maintenance of operating mechanical equipment must be carried out to prevent mechanical failure from affecting production, or mechanical accidents causing casualties. The actual production, safe operating procedures and safety maintenance management system have been studied and formulated to formulate this annual storage tank maintenance and overhaul.
