Fuel storage tanks are primarily of two types: Underground Storage Tanks (UST) and Above-ground Storage Tanks (AST). In the USTs the storage area is located below the ground and fuel has to be pumped out of the storage tanks using sophisticated machines. The ASTs are above the ground, fuel can be pumped out of the tank using a pipe and valve, to control the flow of fuel.
Choosing the Ideal Fuel Storage Tank
Compared to USTs, the ASTs are preferred as the API 650 repairs can be carried out easily with fuel storage units that are above the ground. Other than that, API 650 repairs are quite common. Some of the advantages that you should consider when choosing a fuel storage tank are as follows:
- Installation process: Consider which kind of tank is easier to install. By default ASTs are easier to install as no major excavation work is required to set up the tank.
- Wear and tear of the tank: Since ASTs are exposed to natural elements like heat, wind, rain and snow, deterioration due to exposure is greater in case of surface fuel storage units compared to USTs.
- Expenses due to repair: Most of the tanks require regular repairing to ensure that the tanks are in working condition. As reaching the USTs are more difficult, repairing them is more difficult in comparison to ASTs.
- Maintenance expenses: Corrosion or wear and tear is greater in the case of ASTs, so expenses for maintenance are greater for surface fuel storage units.
- Removal of fuel: As ASTs are located below the surface, pumping out fuel from them is more difficult.
So understand the basic features of the two major types of fuel storage systems and then choose one that meets your requirements.
