Advantange of Undergound Tank:

1. Underground Cooling the tank

2. More Safe in construction

3. Less Land Requirement

Underground oil tanks have the following differences:

Above Ground Tank

  • above-ground oil tanks are not corroded by the soil, have long life,convenient construction and maintenance, low investment, and easy inspection.
  • A sense of security, can not be located in the urban area, and covers a large area and has many fire-fighting equipment.

Underground Tank

  • Buried gas tank is installed underground, it has reliable fire and explosion-proof capabilities, shorten the station and residential distance.
  • Construction is fast and the fire-fighting equipment is simple,
  • Disadvantages: Corrosion by the soil & water, not easy to find leakage, inconvenient for maintenance.
