Abstract
An experimental study of the thermal conductivity coefficient of glass coatings of pipes has been carried out. A device for experimental study of the thermal conductivity of the glass-coating of the pipe has been developed. To a greater extent than the composition, the thermal conductivity of glass depends on the temperature. It has been established that the thermal conductivity of the glass coating increases by several tenths of a watt with an increase in temperature up to 600 ?C. Studies have shown that an increase in the temperature of a glass coating leads to a slight improvement in its thermal conductivity. The highest thermal conductivity is possessed by a coating made of glass of the S-89 and S-52-1 brands. These grades of glass are recommended for pipelines operating at elevated temperatures of heat transfer fluids.
