What is a common material used for vapor recovery piping?

• A. Fiberglass or steel
• B. Plastic and rubber
• C. Aluminum and copper
• D. Wood and concrete

Answer: (A)

The correct choice highlights that fiberglass or steel are commonly used materials for vapor recovery piping due to their durability, chemical resistance, and structural integrity.

Fiberglass piping is known for its lightweight properties and corrosion resistance, making it ideal for handling vapors without risk of degradation over time. In contrast, steel piping provides strength and has a long service life. It can withstand the operational pressures and temperatures typically encountered in vapor recovery systems, all while being resistant to damage from the substances being transported.

Other materials listed have limitations that make them less suitable for vapor recovery applications. For example, plastic and rubber may lack the necessary strength and resistance to certain chemicals, while aluminum and copper could corrode more rapidly in the presence of harsh vapors. Wood and concrete are not viable options given that they are not designed for such applications and would not withstand the operational requirements or environmental exposures of vapor recovery systems.
