The most important equipment in gas station is storage tank ,good quanlity and more safety techology will keep the station running stable and safety ,so how to choose the tank and how many type stroage tank for gas station ,now we can give a simple instruction about this .now we only talking about Double wall underground tank.cause single wall usually not safe.
1. Double wall underground tank we can divide to three classic : SF , FF and SS
A: SF Double wall underground tank
SF Double ‒ wall Tank is a truly innovative product; it has a double ‒ wall structure consisting of a primary steel tank and a secondary FRP tank, and it is equipped with sensor for monitoring leakage. The seamless secondary FRP tank is manufactured using our advanced spray-up technology.
B: FF Double wall underground tank
FF double tank, the inner and outer layers are made of FRP . The tank has a uniform sandwich space and equipped with a leak detector which is connected with the sandwich space. Such tanks have excellent corrosion resistance, light weight, easy installation, Long-term use of economic benefits.
Features: Never rust, reinforced ribs, thick wall structure, the highest strength, the sandwich can be positive pressure leak detection, dry or wet leak detection system, no cathodic protection, no high voltage pinhole detection, It can be easy repaired , tank light, easy construction.
C: SS Double wall underground tank
SS double Wall underground tank, Composed of steel inner tank and tempered glass fiber (or polyester material (PE) outside the tank, also known as jacket tank, tank has a uniform sandwich space and equipped with leak detector In sandwich space , The biggest breakthrough of this type tank is can prevent the leakage of dangerous materials, Avoid environmental pollution, prevent accidents caused by dangerous materials , current market widely used.
Features: easy to rust, thick wall structure lead to Strong pressure resistance , sandwich can be positive pressure leak detection, dry leak detection, steel material to be cathodic protection, can not be high voltage pinhole detection, difficult to repair, Construction difficult, low prices.
