Safe removal method for double-layer oil tank

For a double-layer storage tank, its life will be exhausted when it is removed, but because the risk factor of the double-layer oil tank is relatively high, it is necessary to find a professional when dismantling, and Certain research.Let's take a look at the dismantling method:
 
1. First of all, we must prepare for the construction. We must pay attention to whether the fire protection equipment is prepared in the workplace. It is mainly to prevent sparks from being generated during the demolition and to burn with the residual objects in the double wall oil fuel storage tank. Then we must pay attention to whether the equipment is flat or not. The presence of the personnel to supervise, in order to ensure the safety of the construction site.
 
2. Cleaning of the double wall oil fuel storage tank before demolition. The equipment needed is: explosion-proof fan, foam and ignition point detector. The explosion-proof fan is designed to ventilate the oil tank, remove the gas that can generate explosion, and ensure the safety of dismantling. Then use the foam to clean the residue in the tank. When cleaning, remove the valve in the case, and finally open the hole cover for disassembly. In the process of disassembly, the ignition detector is used to check the oil and gas concentration to see if the concentration in the tank reaches the concentration that can be applied to ensure the safety of dismantling.
 
3. Specific disassembly steps: Install the reinforcement ring on the tank wall below the tank to be removed, weld the lifting lugs, arrange the inner boom, and then hang the chain hoist. The tank wall and the tank bottom are then removed and cut to separate the tank wall from the tank bottom. In the process, the tank wall of the front ring should be cut off first, and the tank can be put down by the chain hoist. The wall of the tank is cut in a circle, and the whole tank wall is cut. Finally, the tank top railings and accessories are cut and the bottom plates are cut in the order of welding.

4. double wall fuel storage tank steel and site cleaning. After all the oil tanks have been cut, it is necessary to deal with the steel plate cleaning site in time, and take safety and environmental protection measures to prevent any safety accidents. This is the specific tank removal process. It must be in the process of removing the double layer oil tank. Pay attention to life safety.
