The article is devoted to one of the most important and urgent tasks in engineering development - obtaining lightweight, non-flammable, environmentally friendly and cost-effective insulating materials. The study shows that the highly porous basalt fiber material is the most efficient insulation for heat-insulating coating of pump-compressor pipes (PCP), operating at temperatures up to 420 °C. The study tested the process of filtration deposition of short basalt fibers with mineral binder from alumina of heat-insulating PCP coatings in the form of cylinders and cylindrical shell. The research relies on the thermal characteristics of basalt fibers and technological features of manufacturing highly porous coating and results in determining the thickness of highly porous insulating PCP coating. During continuous hot air pumping through the PCP samples with thermal insulation and a protective layer of fiberglass it was possible to experimentally establish the heat conductivity coefficient of the multilayer material.
