Corrosion of oil tank bottom plate

Corrosion of the bottom of the double-layer oil tank is a very common phenomenon. What causes the corrosion of the bottom of the pressure vessel and how to deal with it? The main reasons for the corrosion of the oil tank bottom plate are as follows.

1. Related to the material of the bottom plate of the oil tank, the chemical composition of the bottom plate of the double-layer oil tank is not uniform. If the composition is unreasonable, it will accelerate the corrosion of the oil tank.

2. the corrosion caused by welding factors of the pressure vessel bottom plate structure, the anti-corrosion coating is easily burned off during welding, so that the anti-corrosion protective film of the tank bottom will be destroyed, which will accelerate the corrosion of the oil tank bottom plate.

3. The rust removal of the double-layer oil tank is not clean. During the anti-corrosion process of the steel plate, the steel plate and the asphalt primer are not tightly bonded due to the incomplete rust removal, so the anti-corrosion effect of the asphalt anti-corrosion insulation layer is affected. 4. the sealing around the oil tank is not good. If the sealing is not good, rainwater can easily penetrate the bottom of the tank. If it is in a humid environment for a long time, the double-layer oil tank is also easy to be corroded.

Once the bottom of the oil tank is corroded, it will bring great safety hazards, which will have an adverse effect on the entire petroleum industry. Therefore, we must always pay attention to the anti-corrosion work of the double-layer oil tank. Anti-corrosion work must be carried out in a targeted manner. Only in this way can the problem of corrosion of the pressure vessel bottom plate be better solved. If you don't know how to do the anti-corrosion work, you can directly consult the oil tank manufacturer.
