Abstract

We present the results of the investigation of the growth of corrosion fatigue cracks in TBVK 140×11L drill pipes, determine quantitative characteristics of fatigue cracks in the pipes under stresses of different types as functions of the elapsed part of the entire service life, perform their statistical analysis, and propose a method for the prediction of the residual service life of these pipes.
