EXPERIMENTAL RESEARCH OF PERFORMANCE CHARACTERISTICS FOR POLYPROPYLENE PRE-INSULATED PIPES
This paper highlights the main causes of heat losses in heat networks and methods, that can significantly reduce heat losses, which means to increase the efficiency of heat supply systems.
The results of experimental research on determination of thermal and technical characteristics of pre-insulated pipes are presented in the paper. Experimentally, the data on the thermal conductivity of the closed-cell foam samples were obtained.
