What is the highest temperature that HDPE fire truck water tank can handle?

The highest temperature HDPE (High-Density Polyethylene) fire truck water tank can handle is around 130 degrees Fahrenheit. Temperatures higher than that can compromise the tank’s structural integrity, leading to deformation or potential failure. Industry standards typically design these tanks for optimal performance at 100 degrees Fahrenheit, ensuring long-term durability and reliability.

For applications where the temperature consistently exceeds 100 degrees Fahrenheit, consulting the manufacturer for custom-designed tanks is necessary. These tanks can be tailored to safely handle higher temperatures. For example, the design hoop stress for a 100°F service temperature is applied as a maximum hoop stress and is derated for service temperatures above 100°F using a constant service factor of 0.475. This ensures that HDPE water tanks maintain their structural integrity and performance in elevated temperature conditions.
