How should the oil storage tank be removed?
Everything has its own life, and the same is true for the oil storage tank, so how to dismantle the oil tank when it reaches its own life is a problem, because no one knows whether there is still an oil body in the oil tank, or whether there are two Hazardous gases are generated. There may also be a risk of leakage of the storage tank, So how should we dismantle the oil storage tank?
1. Before construction, pay attention to whether fireproof equipment is prepared in the workplace, mainly to prevent sparks from being generated during dismantling and burning with residual objects in the oil tank, and then pay attention to whether the site of the equipment is level and whether there are personnel present to supervise, Only in this way can the safety of the construction site be achieved.
2. For cleaning before removing the oil tank, the required equipment is: explosion-proof fan, foam and ignition point detector. The explosion-proof fan is to ventilate the oil tank, remove the gas that can cause explosion, and remove it safely. Then use foam to clean the residue in the oil tank, remove the valve during cleaning, and then open the hole cover for disassembly. In the process of dismantling, the ignition point detector is used to detect the concentration of oil and gas to see if the concentration in the oil tank reaches the concentration that can be constructed, so as to ensure the safety of dismantling.
3. For specific dismantling, install a ring on the tank wall under the tank to be dismantled, weld the lifting lugs, configure the boom in the tank, and then hang the chain hoist. Afterwards, the tank wall and the tank bottom plate are removed and cut to separate the tank wall and the tank bottom plate as a whole. In the process, a circle of the tank wall should be cut off first, and at the same time, the tank body should be put down by the pull hoist, and a circle of the tank wall should be cut, and so on until the tank wall is cut. It is to cut the railings and accessories on the top of the tank, and cut the bottom plate in the order of welding.
4. It is necessary to do a good job in cleaning the steel and the site of the oil tank. After the oil tank is cut, the steel plate cleaning site should be handled in time, and safety and environmental protection measures should be taken so that no safety accident occurs. This is the specific removal of the oil tank. In the process of removing the oil tank, pay attention to life safety.
