In order to save energy a lot of pipelines in refineries and oil depots and long distance hot oil pipelines need insulation measures. Adding insulation layer is one of the main insulation methods. The derivation process of calculation method of economical thickness for buffed pipeline insulation is mainly introduced in this paper. Then the application conditions and iterative formula and its numerical solution are discussed. A calculation program is compiled and a practical example is calculated. The result indicates that Newton method is simple, effective and precise.
