Температурные напряжения и оптимальное отношение внутреннего и наружного радиусов цилиндрической части сосудов давления парогенерирующих установок

Abstract

The strength condition of the cylindrical parts of pressure vessels (water drums, collectors, heating surfaces, etc.) of steam-generating systems, which takes into account stresses due to the internal pressure and thermal stresses. Stresses due to internal pressure and temperature stresses are obtained using all-known results of the theory of elasticity for infinite cylinders. It is assumed that the strength of the cylindrical parts of pressure vessels of steam-generating systems is limited due to the formation of the plastic deformation in one point at least.
