  The results of research pipes diffusion hardening as an effective method for
increasing the durability and reliability of power equipment are presented. The
experience of commercial operation of pipes manufactured from diffusion
chromized and heat-hardened steel 14 MoV6-3; on the heating surfaces of the
supercritical pressure boilers are generalized. The possibility and
effectiveness of this method on the example of capacities of Trypil'ska CHP are
shown.
