Compartmented SF Double-Wall Tanks
A compartmented SF tank has the same double-wall construction as a standard SF tank, but the steel inner tank is divided by internal bulkheads. Each compartment has its own nozzles and holds a separate fuel grade.
One tank can then store petrol and diesel, or several petrol grades, in one excavation, with one lift and one backfill.
Shells follow the SF-10 to SF-50 range: Q235B inner tank 6 mm, FRP outer tank 6 mm, manufactured to SH/T 3178. The number and volume of compartments are set from your station design.
| Construction | Steel inner tank divided into compartments + FRP outer tank; interstitial space for leak detection |
|---|---|
| Inner tank | Q235B steel, 6 mm |
| Outer tank | FRP, 6 mm |
| Shell sizes | SF-10 to SF-50, 10 to 50 m³ total nominal capacity |
| Compartments | Number and volumes to your station design |
| Manufacturing standard | SH/T 3178 |
| UL certificate | UL 1746, certificate 20161115-MH61687, jacketed underground tanks for flammable liquids, issued 2016; compartmented tanks are within the certified scope |

How many compartments can one tank have?
It depends on the shell size and the nozzle and manway layout. Send your station design with the grades and volumes, and we confirm the arrangement.
What should we send for a quotation?
Total capacity, the volume and fuel grade of each compartment, the nozzle and manway list per compartment, the leak-monitoring method, site and burial conditions, quantity and delivery destination.
Which standard and certificate apply?
Tanks are manufactured to SH/T 3178. Our UL 1746 certificate is 20161115-MH61687, for jacketed underground tanks for flammable liquids, issued 2016. Compartmented tanks are within the certified scope.
How are the tanks delivered?
Complete, by truck, and lifted into the pit by crane on site. Finished tanks are loaded in our workshop with overhead cranes up to 50 t.
