What is a significant factor in pipe material selection?

Resistance to temperature changes is a significant factor in pipe material selection because it directly affects the performance and longevity of the piping system. Different materials react uniquely to temperature fluctuations; some materials may expand or contract significantly, which can lead to issues such as leaks, ruptures, or fitting failures. For example, materials like polyvinyl chloride (PVC) may become brittle in cold temperatures, while metal pipes can expand when heated, leading to possible misalignments or failures in the system.

Considering resistance to temperature changes ensures that the chosen pipe will maintain structural integrity and functionality under varying thermal conditions. This is especially crucial in applications involving hot or cold water, steam, or those exposed to external temperature variations. Choosing a material that can withstand the expected temperature range contributes to overall system reliability and minimizes maintenance costs over time.
