What is a critical consideration when selecting materials for pipes?

When selecting materials for pipes, the temperature rating is a critical consideration because it directly affects the performance and safety of the piping system. Different materials can withstand different temperature ranges, and exceeding these limits can lead to failures such as leaks, bursts, or material degradation. This is particularly important in applications involving hot liquids or gases, which can alter the integrity of the pipe and compromise the entire system. Ensuring the material is suitable for the specific temperature conditions it will encounter helps to ensure longevity and reliability in the piping system.

While other factors like color matching, availability, and environmental impact are important in certain contexts, they do not have the same direct effect on the operational suitability and safety of the piping materials as temperature rating does.
