The effect of moisture content on the performance of polyurethane insulation used on a district heating and cooling pipe.

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

Summary

The performance of polyurethane pipe insulation used in district heating and cooling subjected to underground water attack has been investigated. The objectives of the experiment were to measure the effective thermal conductivity and the moisture absorption rate of polyurethane pipe insulation under conditions similar to those found in operating systems that have failed and to determine the drying rate and the extent to which the insulation can be dried out once the source of moisture is removed. The insulation was tested at pipe fluid temperatures from 1.6 to 126.6 deg C. Results are given.
