First of all, we need to prepare the necessary equipment, the required equipment is: explosion-proof fan, foam and fire point detector. Must be fully prepared to ensure that the inspection is more complete, the explosion-proof fan is to change the air for the oil tank, remove the gas that can produce an explosion, and ensure the safety of demolition. Then use foam to clean the residue inside the tank.
We should remove the valve in a certain order when cleaning, and then open the hole cover for disassembly. In the process of disassembly, the ignition point detector is used to detect the oil and gas concentration, and the construction can be carried out only after the concentration is tested to ensure safety, to see whether the concentration in the oil tank reaches the constructable concentration to ensure the safety of demolition.
Double tank in the disassembly is very necessary, double tank manufacturers when the production of double tank cleaning is for safe operation, I hope that everyone in the cleaning should pay attention to, do a certain amount of preparation work, so that our construction more safe.
【 Why double tank is widely used 】
Once the double-layer oil tank came out, it quickly replaced the status of the traditional single-layer tank and was welcomed by many users. What is the reason for this? Let's take a look.
1. Security
The tank of the double structure leaves a gap between the glass fiber layer between the internal steel shell and the external steel bar, and even if the inner shell leaks, it can ensure that the volume of harmful substances flow only in the gap, and will not immediately overflow the external environmental pollution
2. Environmental protection
The glass fiber outside the double shell tank is guaranteed by special process injection molding, completely sealed outside, in the process of not using gas into the interior to cause erosion, when the glass fiber is an insulator, does not produce electrolytic corrosion, can ensure that in the ordinary environment to ensure the use of 30 years of safety small double tank.
3. Economic practicality
The versatility and high environmental performance of the double tank can indirectly reduce user costs. The tank body is easy to install, there is no need to build an underground storage room, and the tank can be directly buried underground, greatly shortening the construction period and reducing the input cost; Effective protection of the environment from late high environmental costs.
