Precautions for installing LPG underground storage tanks

When installing the underground LPG storage tank, it should be considered to fill the upper surface of the buried tank with some fine sand, and the sand should be evenly and finely crushed. In order to ensure the service life of the storage tank, cathodic corrosion protection should also be done well. This is because the tank body of the underground storage tank is in contact with the minerals in the soil, and will be corroded by acid, alkali, and salt substances during the perennial erosion process, which will cause fatal damage to the tank over time. Therefore, for buried liquefied gas tanks and supporting related equipment, we mainly do a good job in cathodic anticorrosion, so that the accumulation of negative charges (electrons) on the metal surface can prevent the metal from losing electrons and achieve the purpose of protection. After installation, it should be convenient for future inspection and inspection. Special equipment inspection units regularly make corresponding assessments based on the use of the storage tanks, and if necessary, enter the interior of the storage tanks through manholes to check the corrosion of the equipment.
