..., the performance of the spiral pipes under large longitudinal strains is not well understood. The focus of this paper is the tensile strain capacity of spiral pipes. The crack driving forces of flaws in spiral welds under longitudinal tension strains were analyzed for X80 pipes. Unlike the girth weld flaws which...

...). The determination of apparent toughness, CTODA, from the apparent CTODR is demonstrated. The prediction of tensile strain capacity (TSC) using the CTODA and the traditional tangent method is conducted. Similar results are obtained from both approaches. The value of apparent CTODR is found to be relatively...

... 07 04 2011 Tensile strain capacity (TSC) is a critical component of the strain-based design of pipelines. TSC is affected by a number of material parameters, such as the strain hardening rate, weld strength mismatch, and toughness. Girth weld high-low misalignment, internal pressure...

... 07 04 2011 Various industry efforts are underway to improve or develop new methods to address the design of pipelines in harsh arctic or seismically active regions. Reliable characterization of tensile strain capacity of welded pipelines is a key issue in development of strain-based...
