Installing plastic piping in areas subject to extreme temperatures requires careful consideration to maintain performance and longevity. Using insulation is critical because it helps to protect the piping from temperature fluctuations that could cause expansion or contraction, which may lead to stress fractures or leaks over time. Insulation acts as a thermal barrier, preventing the cold or heat from affecting the pipe’s material integrity and ensuring that the fluids within maintain a stable temperature.

This practice not only enhances the durability of the piping but also minimizes the risk of condensation and frost formation on the pipes, which can lead to water damage or mold issues in the surrounding areas. Properly insulated piping can also improve energy efficiency for systems transporting hot or cold water.

In contrast, direct installation on the surface, placement in open air, or encasing in concrete would not provide the necessary protection against temperature extremes, potentially compromising the structural integrity and function of the piping system.
