Precautions before installing LPG underground tanks

LPG underground tanks should be well cathodic corrosion. LPG storage tank tanks and soil minerals in contact, in the process of perennial erosion will be acid, alkali, salts corrosion, over time on the tank will cause fatal damage. Therefore, the liquefied petroleum gas buried tanks and related equipment, we mainly do a good job of cathodic corrosion, so that the metal surface produces a negative charge (electron) accumulation, inhibit the loss of metal electrons and achieve the purpose of protection.
