| Abstract | Modern, cost-effective pipelines are moving beyond the API X70-X80 limits of the 1990s. Over the last few years, more interest has been placed on the X100-120 grades because they are potentially more economical to build and operate. To reach the impressive properties required by these new grades, the proper combination of alloy and rolling process design must be implemented, along with highly controlled interrupted accelerated cooling and hot leveling. This paper discusses some of the underlying physical metallurgy that is required and points out areas where further research and development would be useful. |
