Texture Dependent Mechanical Anisotropy of X80 Pipeline Steel
Advanced Engineering Materials, 2010 AbstractPipeline steel grades API X80 are used for oil and gas transport. The most important mechanical properties of these steel grades are strength and fracture toughness. A remarkable directional anisotropy of toughness and strength were often observed in the plates.

Failure Analysis of API X80 Steel Pipe
ASME 2023 India Oil and Gas Pipeline Conference, 2023Abstract Pipeline structural systems face challenges due to varying loading conditions, which can lead to sudden failures caused by fractures. Enhancing fracture toughness is crucial for improving structural performance. Metallic coatings offer a promising solution to increase pipeline reliability.

Susceptibility of a X80 steel to hydrogen embrittlement
Materials and Corrosion, 2005The susceptibility to hydrogen of a X80 grade steel produced by a thermo-mechanical control process (TMCP) has been investigated by keeping straining notched specimens under continuous charging conditions. Hydrogen charging was carried out either in synthetic seawater under potentiostatic control at − 1000 mV vs.

Quantification of Splitting in X80 Pipeline Steel
Volume 3: Operations, Monitoring, and Maintenance; Materials and Joining, 2018The results of in-depth analysis of microstructure and crystallographic texture of several industrial batches of line pipes with known full-scale burst test results are presented. Several microstructural features promoting splitting are highlighted and quantified using electron back-scattered diffraction (EBSD) data.

Hydrogen induced cracking of X80 pipeline steel
International Journal of Minerals, Metallurgy, and Materials, 2010The hydrogen-induced cracking (HIC) behavior of X80 pipeline steel was studied by means of electrochemical charging, hydrogen permeation tests, tension test, and scanning electron microscopy (SEM). The experimental results indicate that the increase of charging time and charging current density or the decrease of the solution pH value leads to an ...

Transitions in Charpy Energy and Splitting for X80 Pipe Steel
Volume 3: Materials Technology, 2021Abstract Using data obtained for a recent production 48-inch diameter X80 PSL2 pipe, the transition in fracture behavior between fully brittle and fully ductile modes was examined to assess any effects of transverse splits or delaminations.

Toughness anisotropy in X70 and X80 linepipe steels
Materials Science and Technology, 2014The anisotropy of mechanical properties in the context of steels used to fabricate large diameter pipes can be detrimental to the design and performance of the pipes. We examine here the anisotropy of strength and toughness, and with the help of detailed characterisation show that there is a complex interaction between the ability of the steel to ...
