A Study on Stress Corrosion Cracking of X70 Pipeline Steel

Nov 08, 2012 · Consequently, API 5L X70 designation suggests that the minimum yield strength for this steel is 70 ksi (70 ksi or 483 MPa). The mechanical properties of the steel measured at room temperature were provided by the supplier as tabulated in Table 2 which is above the specified value by the API 5L. API 5L Line Pipe Seamless Steel Pipe, US Steel Tubular An understanding of the planned end use and desired method of pipe fabrication is a necessary prerequisite for selecting the appropriate material specification, pipe grade, special requirement (ASTM), API 5L product service level (PSL), API 5L Annex Requirement or CSA Z245.1 category or service group. *U. S. Steel Tubular Products ERW pipe is HFW as defined by API 5L.

Low-Cycle Fatigue Properties of the X70 High-Frequency

  • AbstractIntroductionExperiment ProceduresResultsDiscussionConclusionsData AvailabilityAcknowledgmentsThe strength, toughness, corrosion, and fatigue resistance are the main requirements for evaluating the integrity of a pipeline. In this study, the tensile strength, impact toughness, and fatigue properties of the pipe body and weld joint of an X70 high-frequency electric-resistant welded (HFW) pipe were measured and the effects of microstructure and surface defects at weld joint on properties were discussed. Results show the appearance of a weakened zone at the weld joint of the X70 HFW pipe.
