Thermal insulation of pipelines for the centralized hot water supply generally made by cylinders or mats based on a mineral wool. The criterion of an efficiency of the thermal insulation system is its technical properties, a durability and a cost of production. Modern thermal insulation products made from the mineral stone fiber possessing high chemical resistance. A structure of the products is such that the fiber is in a strong bond and has a volume-oriented state. Complicated bound structure gives to the product additional strength characteristics, and it is fixed due to curing of a binder. The substances having high resistance in the cured state are used as a binder. Accordingly, a reserve for increased durability is the completeness of curing of the binder. Which, in turn, depends on the organization of the process of thermal treatment. Cost reduction caused by the use of a binder with a curing temperature of up to 150 ° C. The possibility of justifying an application of epoxy modified binder with a latent hardener is given in the article, and the methodology of the choice of parameters of the mode of thermal treatment of mineral wool cylinders with this type of binder is also stated. The methods are based on graphics intended for selecting parameters of thermal treatment of mineral wool cylinders obtained as a result of engineering interpretation of mathematical models with empirical coefficients, and also a computer program for calculation based on the algorithm developed by the authors.
