概要
This study is confirmed IHSI which is one of preventive maintenance techniques for stress corrosion This study is confirmed IHSI which is one of preventive maintena nce techniques for stress corrosion cracking, can be applied to pipe with crack. The results were applicable under certain conditions by the test which was used pipe with 3 / 8 depth crack. Following four items were confirmed by this test. 1. Not affect for cracks and joints, 2. Residual stress would be improved with the tip of t he crack and can be suppressed with crack growth, 3. Residual stress would be improved around the crack, 4. It can be effective for preventing SCC at non crack area.
