摘要

The limit of long-term strength and destruction of pipe metal from a set of superheater spare parts are investigated. It is shown that softening characterizes the durability parameter of I. I. Trunin, structural transformation —the relative content of molybdenum in carbides. Formulas for calculating the allowable stress in the metal, the equivalent operating temperature and the resource characteristics of coils are proposed.
