Recently, the need for research in high quality Heat-transfer Tubes of Steam Generators(Alloy690) for life extension of APR1400 equipment is increasing. The U-ending cold working of Heat-transfer Tubes have a great influence on final product quality of steam generators as Pilgering(or Drawing) and Heat treatment p rocess have. There are permissible ovality, minimum wall thickness, tolerance of bending radius, residual stress as quality valuation factors.
But, most producers of alloy690 Tubes, they are depending upon their own working experience(skill), so it is not existing for quality improvement to quantitative form control factors of U-bending cold working.
Accordingly, through this study, we tried to verify of Analysis methodology as modification and ‘spring back’ condition, and reduce experimentation range, use in base data for U-bending cold working of Alloy690 Heat-transfer Tubes, and analyze the interrelation between quality valuation factors and from control factors of U-bending cold working.
