Abstract: A new method is presented for estimating residual stresses produced in a pipe made by surfacing weld. By focusing on the concept and the feature of inherent strain causing the residual stress, ...

Abstract: Full-scale burst tests were carried out on X70 line pipes, 48 in. o. d. × 0.720 in. w. t., with air and rich and natural gas as the pressurizing gases. The experimental results indicated ...

Abstract: High Strength Line Pipe Research Committee organized by The Iron and Steel Institute of Japan carried out two full-scale burst tests on X 70 line pipes, 48 in. o.d. × 0.720 in. w.t., ...

Abstract: A shear fracture propagation in steel was investigated with the aid of spring-loaded DCB testing, that was developed as a laboratory simulation test of shear fracture propagation in pressurized ...

Abstract: Full-scale burst tests were carried out five times on line pipes of 48 in. o.d. × 0.720 in. w.t., Grad. X-70 manufactured by the controlled rolling and the quenching and tempering ...

Abstract: A high-speed video camera was combined with a newly developed optical system to measure time resolved two-dimensional (2D) temperature distribution in flames. This diagnostics has been applied ...
