What materials should not be used in vapor recovery system installations?

The selection of materials for vapor recovery system installations is critical to ensure safety, efficiency, and longevity of the system. Using materials that are susceptible to corrosion from hydrocarbons is a significant concern. Hydrocarbons can cause various materials, particularly certain metals and plastics, to degrade over time, leading to leaks or failures in the system. Therefore, selecting corrosion-resistant materials for components like piping, tanks, and other parts of the vapor recovery system is essential to prevent contamination of vapor and to maintain operational integrity.

Choosing materials that are highly reflective, lightweight and flexible, or capable of withstanding high temperatures generally does not directly relate to the failure risk associated with vapor exposure. While these characteristics might be relevant in other contexts—such as insulation or thermal resistance—they do not address the core concern of compatibility with hydrocarbons that could lead to system malfunctions. Thus, the emphasis on corrosion-resistant materials is paramount to safeguard against the specific threats posed by hydrocarbons in vapor recovery systems.
