Full-scale burst, crack-arrest testing vets X-120 line pipe

Based on a presentation to the 13th International Offshore and Polar Engineering Conference, Honolulu, May 25-30, 2003. A new high-strength steel with a specified minimum yield strength of 120 ksi has been developed for line pipe applications (OGJ, Dec. 1, 2003, p. 56).1 Because existing specifications were not originally intended for X-120 and no service experience exists for this grade, full-size pipe tests and finite-element analyses were conducted to evaluate structural performance.This article presents results of burst and fracture-arrest studies and analyses that demonstrate sufficient pressure-containment capacity. For crack arrest, full-size tests evaluated the intrinsic arrestabi...
