What material is most commonly used for fuel-oil piping?

• A. Plastic only
• B. Only stainless steel
• C. Copper or steel
• D. Rubber

Answer: (C)

The most common materials used for fuel-oil piping are copper and steel due to their mechanical properties, corrosion resistance, and suitability for high-pressure applications. Steel, particularly when galvanized or treated, provides robust durability and strong resistance to the conditions typically present in fuel-oil systems. Copper is favored for its excellent corrosion resistance and the ability to handle various temperatures without degrading. The use of copper and steel also aligns with industry standards and regulations that dictate materials suitable for safely handling fuel oils. These materials are compatible with the chemical composition of fuel oils and can withstand the operational pressures and environments associated with fuel-oil storage and distribution. Other materials mentioned in the options have limitations that make them less appropriate for this application. For instance, plastic can degrade under certain chemical exposures and may not meet the necessary pressure ratings for fuel-oil systems. The use of only stainless steel might be overly restrictive and costly, as it may not be as widely used in this specific application compared to copper and steel. Rubber is generally not suitable for fuel-oil piping because it can deteriorate with prolonged exposure to oils and may not offer the required structural integrity.
