Abstract
A calculation-experimental method is proposed to predict the remaining life pipe steel. It is based on a comparative analysis of the dependence of the recrystallized grain size on the degree of preliminary plastic deformation before and after operation. This method is used to estimate the remaining life of gas main pipes having operated for a long time.
