A Test Protocol for Comparison of the Moisture Absorption Behavior of Below-Ambient Piping Insulation Systems Operating in Hot-Humid Environments

Source

The value of adding insulation to piping systems operating at below ambient temperatures has been demonstrated by many successful installations. For other systems operating at these temperatures, the adverse impact of moisture migration into the insulation system during operation has caused many premature failures. The objective of this paper is to propose a standard test protocol for evaluating an insulation system's moisture adsorption response when exposed to a design combination of ambient temperature and relative humidity. Test results, developed using this protocol, for eight chilled water piping insulation systems are presented and compared to simplified model results.
