Rationale

There are large quantities of below ground, insulated pipes that carry steam or hot water for district energy heat distribution systems. Often, due to rain and / or melting snow, resulting in a high water table, the insulated pipes become temporarily immersed in water, resulting in the pipe insulation becoming saturated with water. When the steam or hot water subsequently dries the pipe insulation, it can become thermally degraded. This is a practice for determing the extent of that thermal degradation.
