| Abstract | Offshore pipelines and risers constructed from carbon steel have reduced levels of performance when operating in a sour environment. Sour service environments are defined by NACE International specification MR0175 as “fluids containing water and hydrogen sulphide (H2S) that is at a total pressure of 0.4Mpa (65psia) or greater and if the partial pressure of hydrogen sulphide in the gas is greater than 0.0003MPa (0.05psia)”. The acidity of the environment is below pH 3.5 and carbon dioxide and chlorides are also normally present.
This document provides technical information for pipeline fabrication and welding technology in sour service which characterizing material properties i.e. fracture toughness and fatigue crack growth rates.
So the special care is required for design, procurement, construction, operation and maintenance of pipeline for sour service condition. |
