Abstract
Relationship between the rate of growth of corrosion cracks and stress intensity factor was described on the basis of the static corrosion crack resistance diagram. The main working hypothesis that crack growth is of a discrete nature was proved by means of analytical scanning microscopy.
 
 
Keywords: pipe steels, corrosion cracks, diagram of static corrosion resistance, acoustic emission, electron microscopy, hydrogen embrittlement zone
