Abstract
Induction Heating Stress Improvement (IHSI) has been proved as a strong countermeasure for intergranular stress corrosion cracking (IGSCC). IHSI is also expected to suppress further crack extension of existing cracks. The applicability of IHSI to a flawed pipe was investigated using a thermo elasto-plastic FEM program. IGSCCs with depths up to 50% of the pipe thickness are considered. It is found that there is a large margin for the extension of the crack during IHSI. Effectiveness of IHSI as an eternal countermeasure for IGSCC depends upon the level of service stress as well as the crack size. A long circumferential crack will be prevented from further extension by IHSI if the depth is under 30% of the thickness and the service stress is under 0·75 S m . For practical use, a simplified procedure to predict IHSI effectiveness for preflawed pipe is proposed making use of calculation of K by the superposition principle.
