Effect of underground water attack on the performance of mineral wool pipe insulation.

Author(s) : CHYU M. C., ZENG X., YE L.

Summary

The pipe fluid temperature was tested from 1.6 °C to 232.2 °C. The surrounding water was maintained from 7.7 °C to 37.7 °C to simulate the possible conduit water temperatures when the system fails. Under heated conditions (pipe temperature higher than water temperature), the effective thermal conductivity of the wet mineral wool insulation can be, depending on the insulation and the surrounding water temperatures, 50 times higher than that of dry insulation.
