The ways of external protection of oil pipelines, their advantages and disadvantages were described. A method for protecting pipes using foam glass products, based on local raw materials, was proposed. The powder technology of the batch preparation and the hydration mechanism of foaming through the interaction of alkali and silica were chosen for this study, based on the existing methods of foaming of silicate raw materials. Compositions of the batch were developed, their foaming was carried out in the temperature range, corresponding to the pyro-plastic state, the effectiveness of the additional introduction of foaming substances was analyzed. The macro-and microstructure of the specimen, as well as their phase composition, were studied. The optimal composition and optimum foaming temperature for the production of foam glass materials were selected.
