Factory inspection requirements for double-layer buried oil tanks

The double-layer buried oil tank is a container for storing oil. Its safety performance and various indicators are closely related to the safety during future use. Therefore, after the double-layer buried oil tank is processed and before leaving the factory, strict inspection work is required to ensure that the quality of the double-layer buried oil tank meets the standards. Next, I will tell you about the factory inspection of double-layer buried oil tanks.
 
1. First, perform a water-filling experiment on the double-layer buried oil tank to ensure that there is no problem in the sealing of the tank wall and the adhesion of the wall plate and the weld.

2. The ultrasonic method is used to inspect the double-layer buried oil tank to test whether the wall thickness of the oil tank body reaches the standard.

3. Use welding oil to check the weld of the underground double-layer oil tank, because the penetration of the burning oil is very strong. If there are no mottled traces after applying the burning oil, then the weld connection is very strong.

4. Use the magnetic flux leakage scanning technique to check whether the bottom of the double-layer buried oil tank is corroded. In general, if the magnetic flux scanning sensor does not change, then the tank bottom is qualified. 5. Finally, you need to measure the pressure at the bottom of the oil tank and calculate the amount of medium in the tank. If the quality continues to decrease, it will clarify the leakage.

The above are the factory inspection requirements for double-layer buried oil tanks. I believe everyone has a better understanding of this. Although manufacturers will carry out strict inspections after the production of double-layer buried oil tanks is completed, when we purchase double-layer buried oil tanks, we still need to perform corresponding quality inspection to avoid quality problems.
