The stress state of the glass coating in a pipe in the petrochemical industry is studied. Formulas are obtained for determining the longitudinal, radial, and tangential stresses arising in the cross sections of a coating. The stress state of a glass coating of a pipe was studied experimentally. The tensile strength of the coating at high temperatures is presented.
