About this Abstract
Meeting 2017 TMS Annual Meeting & Exhibition
Symposium Pan American Materials Congress: Materials for Oil and Gas Industry
Presentation Title Structural Integrity of Pipelines
Author(s) Anibal Carlos Di Luch, Nicolas Oyarzabal
On-Site Speaker (Planned) Anibal Carlos Di Luch
Abstract Scope This work is part of a comprehensive structural integrity program of pipelines in Argentina, in particular it is applied to a gas pipeline in the North-East region. It is composed mostly of pipes API 5L grade X70 PSL 2, 24 inches nominal diameter and 11.9 mm wall thickness, manufactured by roll bending expand RBE and submerged arc welded SAW inside and outside. For girth welds assessment API Standard 1104 and BS 7910 guidelines are followed. This study is based on engineering critical assessment (ECA) and fitness for service (FFS) and it is required to perform complex tests and calculations like CTOD testing to assess both the weld metal and the heat affected zone. A sensitivity analysis is finally presented showing the effect of imperfection length and height on a failure assessment diagram (FAD).
