“…The precipitation ofNb(C,N) during finish rolling prevents austenite reoystallization producing a fine pancaked austenite microstructure upon completion of rolling. As demonstrated in earlier work [3], it is important that the reduction below the temperature of no recrystallization (T m ) be maximized. This promotes formation of a uniform, fine-grained microstructure.…”

Recent construction of pipelines in Canada has seen a trend towards higher operating pressures with greater wall thicknesses and/or higher strength pipe. At the same time, Grade 550 linepipe is becoming accepted as the standard for new construction. The production of high strength grades in wall thicknesses over 12.5 mm presents a new challenge. The increased wall thickness and higher strengths tax manufacturing equipment to the fullest. IPSCO has recently completed the production of 1150 km of 14.2 mm spiral-welded Grade 483 linepipe for the Alliance Pipeline. This paper will examine the technical issues associated with the production of this pipe at the Regina steel mill. Successful production trials at IPSCO’s new steel mill in Montpelier, Iowa, which incorporates new process technology, are also described. Production of linepipe with strength exceeding 550 MPa will also be examined.

“…IPSCO has previously demonstrated the capability of producing Grade 550 linepipe [3]. Looking towards the future, the feasibility of producing Grade 620 or Grade 690 linepipe of the same gauge and diameter as the Alliance order was also examined.…”

In this study, the deformability of high-grade pipelines subjected to an axial compressive deformation was experimentally and analytically discussed. Six cases of axial compression experiments with high-grade line pipe were carried out. The pipe specimens had various material properties and wall thickness. Finite-element analyses were also carried out and verified the reliability. Then, a finite-element analysis method for evaluating the deformability of the line pipe was established. By using this method, parametric studies were carried out. The effects of the strain-hardening behavior and pipe geometry on the deformability of the high-grade pipelines were examined.
