Corrosion of Welded X100 Pipeline Steel in a Near-Neutral pH Solution

Journal of Materials Engineering and Performance, 2009
In this work, electrochemical corrosion behavior of a welded X100 pipeline steel was studied in a near-neutral pH solution by electrochemical scanning vibrating electrode technique combined with metallographic and scanning electron microscopy/energy dispersive x-ray analysis.

Modeling the fatigue crack growth of X100 pipeline steel in gaseous hydrogen

International Journal of Fatigue, 2014
Abstract This work proposes a phenomenological fatigue crack propagation (FCP) model for API-5L X100 pipeline steel exposed to high-pressure gaseous hydrogen. The semi-empirical model is predicated upon the hypothesis that one of two mechanisms dominate the fatigue crack growth (FCG) response depending upon the crack extension per cycle ( da / dN ...

Anisotropic Behaviors for X100 High Grade Pipeline Steel Under Stress Constraints

2017
Because of the manufacture process of high grade pipeline steel, the anisotropic behaviors appeared in different directions, including both properties and microstructure. In this paper, mechanical properties and microstructures for X100 high grade pipeline steel were investigated with a series of tests, including not only experiments but also ...

Study on the Toughness of X100 Pipeline Steel Heat Affected Zone

2014
Microstructure-property correlation of heat affected zone (HAZ) in X100 longitudinal submerged arc welding (LSAW) real weld joint was studied in this paper. Coarse grained (CG) HAZ and intercritically reheated coarse grained (ICCG) HAZ were characterized by optical microscope (OM), electron backscattered diffraction (EBSD).

Effect of Prestrain and Aging on Mechanical Properties of X100 Pipeline Steels

ICPTT 2013, 2013
Harsh environments that may displace a given pipeline beyond the elastic limit include: seismic areas (that may be susceptible to soil liquefaction, fault displacement or soil instabilities), continuous or discontinuous permafrost (that may result in thaw settlement and frost heave), and construction.

L51924 Evaluation of Welding Consumables and Processes for X100 Steel

2003
The primary objective of this study was to evaluate the mechanical properties of weld metals deposited using a number of commercially available welding consumables and welding processes. The secondary objectives of this work included characterizing weld metal microstructure, assessing hydrogen-assisted cracking susceptibility of the weld metal and X100
