What is the maximum temperature permitted for liquids in pipes embedded in concrete walls?

The maximum temperature permitted for liquids in pipes embedded in concrete walls is indeed 150 degrees Fahrenheit. This temperature limit is established to ensure the integrity of both the piping material and the concrete. As liquids, particularly hot ones, can expand and contract, maintaining a maximum allowable temperature helps prevent excessive thermal stress that could lead to cracking, damage, or failure of the concrete structure or the piping itself. Additionally, a temperature limit is critical to ensure safety, as piping systems exposed to higher temperatures could pose risks of leaks or even burst scenarios, affecting not just the immediate surroundings but also the structural stability of the concrete walls into which they are embedded.

Other temperature options would be insufficient to ensure the durability and safety of such installations. Choosing a temperature below this threshold could lead to limitations in the types of systems that could effectively operate in tandem with these embedded pipes, impacting both the functionality of the system and the performance of the concrete structure over time.
