description: The work is based on evaluating of using extruded polystyrene foam as the main material for insulation of pipelines in St. Petersburg. The object of research is extruded polystyrene foam. The subjects are mechanical properties of polystyrene and its change during the time. Analysis of existing scientific works, data collection and systematization of data are conducted in this research. The change of creep velocity was evaluated by stepped isothermal method and critical temperature of polystyrene was found. Ways of increasing the critical temperature have been proposed. The results obtained were compared with the results published in the scientific literature earlier. Recommendations on the use of polystyrene as a thermal insulation material for main pipelines are proposed.
