Gas-filled thermal insulation use in heat supply

Abstract

The possibility of applying a new type of thermal insulation, which will significantly reduce heat losses during transportation of heat, increase the service life of the pipeline, and reduce the cost of heat insulation work considered. Using multi-layer thermal insulation, which is a system of closed, sealed microvolumes (pores), which are filled with carbon dioxide proposed. As a shell, high-density polyethylene is used. Such a film can be used as a ready-made material for insulation of pipelines. Depending on the temperature of the pipeline, the required number of layers of thermal insulation is applied to the pipeline.
