Crack nucleation and propagation in high strength welded pipes

International Seminar on Welding of High Strength Pipeline Steels

2013
Pyshmintsev, I Yu
The effect of local embrittlement of the weld joint on the structural strength of high-strength pipe is discussed in the paper. The results of hydraulic tests of Х70 grade pipes having a longitudinal surface notch in the base metal and weld joint are presented. By using examples of full-scale burst tests, features of ductile fracture propagation in spiral pipes are displayed.
