How can extreme temperatures affect UST operations?

Extreme temperatures can significantly impact the integrity of the materials used in Underground Storage Tanks (USTs) and their overall system performance. High temperatures may lead to the expansion of fuel and other substances, potentially causing structural stress on the tank and its components. This can result in leaks, material degradation, or even failure of seals and fittings, which compromises the safety and effectiveness of the UST.

Conversely, extremely low temperatures can cause fuel to thicken or change phase, complicating the dispensing process and affecting fuel flow rates. Such temperature fluctuations can also impact the efficiency of pumps and valves, complicating operations and potentially leading to equipment failures.

Understanding the implications of extreme temperatures is crucial to maintaining UST systems in good working order and preventing environmental hazards due to leaks or spills. Therefore, recognizing how these conditions can affect material integrity and system performance is essential for technicians in ensuring safe and efficient UST operations.
