Abstract
Procedure for determination of parameters of a simplified static corrosion crack resistance diagram for pipe steels in soil water solution environment is described. The possibility of plotting simplified diagrams using small-sized Charpy-type specimens with a pre-induced fatigue crack is shown. The use of acoustic emission for fixation of crack growth allows the test time to be reduced to 5-7 days.
Keywords: static corrosion crack resistance diagram, main pipelines, acoustic emission, stress intensity factor, crack growth rate
