Abstract

Recently, troules have been experienced successively wherein stress corrosion cracking occurs to cause even a leakage of water during the final stage of the propagation of a crack while a nuclear power plant is in operation. The heataffected zone of circumferentially butt-welded joint between a pipe and a nozzle is said to have the most frequent stress corrosion cracking in the equipment commercially used. Assuming such risk, this paper discusses correlation between the notch dimension of stainless steel pipe with circumferential surface notch and burst criteria of pipes such as the burst pressure. The burst pressure of test pipes with circumferential notch does not show simple change against the notch dimension. Namely, if pipe has a partial circumferentially notch, a neutral axis moves and the pipe will receive stress by bending moment besides axial tensile stress due to internal pressure.
