A S/F double wall oil storage tank is a type of storage tank designed for the safe storage of oil or other petroleum products. S/F stands for "Single Wall/Flexible Membrane," meaning that the tank has two layers of protection.
The outer layer is a steel tank that provides strength and protection, while the inner layer is a flexible membrane that prevents leaks and spills. The space between the two layers is called the interstitial space, which is monitored for any leaks or damage using a leak detector.
This type of tank provides an extra layer of protection against leaks and spills, making it a popular choice for both above-ground and underground storage of oil and other hazardous materials.
