How to solve the corrosion problem when using double oil tank

We all know that double-layer oil tanks are subject to different degrees of corrosion problems because they are buried underground all year round. And the corroded oil tank will bring various problems. So, how to solve the corrosion problems related to pressure vessels?

1. The inner and outer walls of the double-layer oil tank interlayer should take stricter anti-corrosion measures, such as paint, sacrificial anode, and corrosion inhibitor, to solve the corrosion problem of the oil tank. Choose a good coating to ensure that the coating has strong rust resistance, water resistance and oil resistance. The coating should have very good cathodic protection performance.

2. Double-layer oil tanks are evacuated before leaving the factory. When the leak detection system is installed on site, rubber gaskets must be installed and tightened between the flange of the detection pipe and the flange of the leak detector to prevent rainwater from leaking into the tank and interlayer air. In and out.

3. Brush the coating on the bottom of the oil tank. Choose a paint with higher corrosion resistance to brush the bottom of the oil tank to reduce the damage to the bottom of the pressure vessel by corrosion. Secondly, use conductive material with higher potential to make the inner wall of the bottom of the oil tank to avoid the formation of iron at the bottom as the anode, thereby increasing the corrosion of the double-layer oil tank. 4. At present, most double-layer oil tanks use the "dry" alarm method, that is, a liquid sensor probe is installed in the detection tube and connected to the alarm through a cable. Although the "dry" leak detection method is simple and easy to implement, there are also problems such as prone to corrosion and possible underreporting of perforations on the outer layer of the tank. The "wet" leak detection method completely drives the oxygen out of the interlayer. The liquid medium can be added with corrosion inhibitors to basically solve the corrosion problem. It can also detect the perforation leakage of the inner and outer layers at the same time under various liquid
level conditions to achieve no leaks and full coverage ,Safe and reliable.

The above are the related issues explained by the pressure vessel manufacturers. I hope it will be helpful to you.
