Stainless Steel Gas Tanks
A stainless steel gas tank stores gasoline in a strong, corrosion resistant stainless steel container until it is released into the engine of a motor vehicle or evaporates into the air. As part of an engine system, the gas tank is typically mounted into the rear of an automobile between the chassis and exterior or, for other modes of transportation, into an available space.
Many motorcyclists and classic car enthusiasts are attractedto the high polish of a stainless steel gas tank and its ability to be custom fitted tothe vehicle. Stainless steel tank manufacturers strive to produce tanks thatare airtight and without cracks or leaks so that gasoline does not diffuse intothe air or drip out of the tank. As a storage container, the tank itself has nomoving parts; for an average automobile, it is usually rectangular with roundedcorners and a capacity of around 16 gallons.
Airplanes carry from around 6,000 to more than 80,000 gallons of fuel inmultiple tanks that are mounted in the wings or installed in a designatedcompartment. Stainless steel is gaining popularity as a material for gas tanksas it resists rust, does not deposit impurities into the gas and has minimalcracking over time.
Traditionally, gas tanks are made from molded ceramic,carbon fiber or steel coated in zinc or aluminum.
These materials are prone to splitting, flakingand corrosion, which lower the quality of the gasoline and can decrease theengine’s performance. If the tank begins to develop cracks, gasoline can diffuseinto the air which is costly and damaging to the environment.
Stainless steel, however, does not break downor get worn away, and the tanks maintain a good seal, especially if they arecarved from a billet.
A billet is arectangular piece of steel, and they are often melted down then cast or forgedinto mechanical and industrial products. The disadvantages of those processesis that they result in thick and thin areas in the steel which can warp andcrack from internal stress, and a weaker steel must be used so that it can beworked properly. If the gas tank is carved from a billet of stainless steel
, itwill have even walls and can be made from a higher grade of steel. Gas tankscan also be welded from sheets of stainless steel or, for larger tanks, boltedtogether. A fuel delivery system is also welded or soldered into place withtubes to deliver the fuel to the engine and pressure gauges to provide theoperator an accurate reading of how much gas remains.
