Splitting susceptibility in modern X80 pipeline steels

Materials Science and Engineering: A, 2020
Abstract The microstructure and crystallographic texture of modern industrially produced API X80 grade pipeline steels were studied to identify the factors associated with the phenomenon known as splitting, which can occur on the fracture surfaces of Charpy, drop-weight tear test and full-scale fracture propagation tests.

Hydrogen induced cracking of X80 pipeline steel

International Journal of Minerals, Metallurgy, and Materials, 2010
The 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 ...

Precipitation behaviors of X80 acicular ferrite pipeline steel

International Journal of Minerals, Metallurgy, and Materials, 2011
The precipitation behaviors of X80 acicular ferrite pipeline steel were investigated by using transmission electron microscopy (TEM) and energy dispersive spectroscopy (EDS). The results show that dendritic precipitates in the as-cast steel slabs precipitate mainly in grain boundaries, and these dendritic precipitates dissolve and re-precipitate to two

Quantification of Splitting in X80 Pipeline Steel

Volume 3: Operations, Monitoring, and Maintenance; Materials and Joining, 2018
The 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.

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.

Fracture Toughness and Application of X80 Pipeline Steel

Materials Science Forum, 2019
The fracture toughness of X80 pipeline steel, which has been widely used in China, plays a key role in pipeline safety insurance. In order to know the accurate fracture toughness of X80, the methods of acoustic emission and high K ratio have been carried out to judge the initiation of crack propagation and improve flatness of fatigue pre-crack front ...
