The evaluation of optimal insulation has been presented for insulated pipelines and spherical tank. In the majority of the insulation problems the objective function and the restrictions are nonlinear. An efficient nonlinear optimization method was applied for the minimum cost design of insulated pipelines and spherical tank with constrains. The objective (cost) function includes the heat loss and the material costs of the insulating layers and material costs. The thickness of insulating layer and the minimum costs depending on the temperature of surrounding air are presented.
