Calculation-experimental method for evaluation of residual life of welded joints in steam pipelines

F.A. Khromchenko, R.N. Kalugin

OJSC «VTI», Moscow, Russian Federation.

Abstract
Calculation-experimental methodological approach to evaluation of residual life of steam pipelines on the basis of long-time strength and structural state (microdamage) of metal of welded joints under creep conditions is considered
Keywords: power plants, welded steam pipelines, long¬time strength, creep, residual life, safety factor for strength
