What Are the Considerations Regarding the Materials of Fuel Dispensers With Tanks

Fuel dispensers with tanks play a crucial role in the fueling process, and the selection of materials for their construction is of great significance. Each component requires specific materials to ensure optimal performance, durability, and safety.

Tank Materials

The tank of a fuel dispenser is typically made of steel. Carbon steel, with its high strength and relatively low cost, is a popular choice. However, to prevent corrosion, especially when storing fuels like gasoline and diesel, the steel is often coated with corrosion - resistant materials such as epoxy or polyethylene. Fiberglass - reinforced plastic (FRP) is also increasingly being used for fuel tanks. FRP tanks are lightweight, highly resistant to corrosion, and have excellent insulating properties, reducing the risk of condensation and subsequent corrosion.

Hose Materials

Fuel hoses need to be flexible yet durable. They are usually made of synthetic rubber or thermoplastic elastomers. These materials are resistant to fuel permeation, ensuring that fuel does not leak during the dispensing process. Inner linings of hoses are often made of materials like nitrile rubber, which has excellent chemical resistance to fuels. The outer cover of the hose is designed to be abrasion - resistant, protecting the inner layers from damage during regular use.

Nozzle Materials

Fuel nozzles are typically made of metals like aluminum or brass. Aluminum is lightweight and corrosion - resistant, while brass offers good durability and resistance to wear. The components within the nozzle, such as seals and valves, are made of materials like fluorocarbon rubber or silicone. These materials have high resistance to fuels and can withstand the pressure changes during fuel dispensing.

Housing Materials

The housing of the fuel dispenser is usually constructed from stainless steel or high - density polyethylene (HDPE). Stainless steel provides excellent strength and protection against physical damage, while HDPE is lightweight, corrosion - resistant, and can withstand harsh environmental conditions.
