In this paper, temperature distributions of the fluid and pipeline are determined using the explicit finite difference method. Transient temperature responses of the fluid and pipeline wall together with thermal stresses on internal and external wall surfaces were obtained from numerical solution. The optimum time changes of the steam temperature during pipeline heating was calculated by using the Duhamel's integral.
