Designing reliable delivery systems and managing the complexities of modern alternative fuels.
Traditional, highly durable, but labor-intensive due to numerous fittings. FRP is the standard for large-diameter underground mains as it is corrosion-proof.
Modern standard for underground runs. Installed inside a larger "chase" pipe, allowing for replacement without digging. Fewer joints = fewer leak points.
Suction: Pump is inside the dispenser. Limited distance (fuel is pulled). Good for small sites.
Pressurized: Submersible Turbine Pump (STP) inside the tank pushes fuel. Standard for high-volume stations.
Hydroscopic (absorbs water). Requires nickel-plated fittings and alcohol-compatible tank linings to prevent corrosion and phase separation.
Acts as a solvent, cleaning sludge from old tanks which can clog filters. More susceptible to microbial growth ("bugs").
Chemically identical to petro-diesel but made from renewables. Fully compatible with existing infrastructure (drop-in replacement).
Categorize the piping materials.
Drag items from the pool into the correct category bucket.
