Heat Losses of Main Pipelines Depending on Thermal Conductivity of Insulation Materials
Abstract
The article focuses on the problem of heat losses of main pipelines due to moisture of insulation materials (mineral wool, polyurethane foam). The experimental results concern the moisture (partial, full) effect on thermal conductivity of insulation materials. The calculations and comparative analysis are given for heat losses using the standard techniques and TeploRoTr-2 software system. Research allows estimating the impact of the number of moisture-drying out cycles for mineral wool and polyurethane on heat losses of the main pipelines.
