The application of polymer composites (hereinafter referred to as PC) as a constructional material for gas-escape channels of industrial chimneys and ventilation pipes in most cases is reasonable and effective. However, similar to the use of any other material, there is a certain area of the PC rational application as well as certain construction forms, which allow the ultimate usage of the material resources compensating its disadvantages. This paper provides the analysis of the PC properties, which determine their rational application field in the gas-escape channels of industrial chimneys and ventilation pipes construction. The proposed method of PC design characteristics’ appointment for the gas-escape channel construction takes into account temperature-time factors. For a structure made of the new improved heatproof PC, it is proposed to use common (base) PC coefficients values for a bearing capacity design, however, amending their temperature scale in compliance with heat proof changes relative to the base PC while setting the temperature-time durability coefficients. The construction schemes being considered are the most optimal from the manufacturing and erection points of view. Some new tested elements of the gas-escape channel and connecting joints are proposed.
