Revitalization of steam pipeline wall thickness

Steam pipeline is used for water steam transport. Described boiler of thermal power unit has nominal steam production of 375 t/h and the power of 110 MW. Current available unit power is 80 MW. Steam pipeline material is chosen for boiler operation conditions and unit turbine of 200000 operative hours. Fallowing materials are considered: 15Mo3, 13CrMo44, 14MoV63, 10CrMo910, X20CrMoV121, X10CrMoVNb91. Material selection is based on the attemption that route of steam pipeline stays approximately the same and the new material has to have the same or better mechanic properties.
