Corrosion Mechanism of a X100 Pipeline Steel in NACE Brine at 1000 rpm

ECS Transactions, 2021
This work shows the research about the corrosion mechanism analysis of a X100 pipeline steel immersed in NACE brine under turbulent flow conditions (1000 and 5000 rpm) at room temperature and atmospheric pressure of Veracruz Port. In order to study the hydrodynamic conditions, a rotating cylinder electrode (RCE) was used, while to the electrochemical ...

Experimental Investigation of Slant Crack Propagation in X100 Pipeline Steel

2008
Failure information from full-thickness burst experiments on long distance gas transportation pipelines has shown that unstable fractures propagating in the pipeline axial direction are dominated by ductile slant shearing [1]–[3]. Different test samples, e.g.

The Effects of Chloride Droplet Properties on the Underoil Corrosion of API X100 Pipeline Steel

Corrosion, 2019
The corrosive environment expected to form in diluted bitumen pipelines was explored by simulated exposure with a paraffin oil-covered chloride droplet on API X100 pipeline steel. The effects of droplet volume, chloride ion concentration, temperature, initial pH, and cation species on the underoil droplet corrosion behavior of API X100 pipeline steel ...

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 ...

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).

Mechanical Properties of the Heat Affected Zone of an X100 Grade Pipeline Steel

Materials Science Forum, 2013
The microstructure and mechanical properties of an X100 grade pipeline steel were investigated by the thermal simulation tests performed on a Gleeble-3500 thermal simulator. The results show that the steel has excellent weldability. Even if the weld heat input gets 40 kJ mm-1, the low impact toughness energy in welding coarse grain heat affected zone ...

Microstructure and Mechanical Properties of X80/X100 High Deformability Pipeline Steel

Advanced Materials Research, 2011
In the present study, X80 and X100 grade high deformability pipeline steels have been processed by using TMCP and followed two-stage cooling process. The microstructures of the X80HD (HD, high deformability) and X100HD steels were both characterized by ferrite-bainite dual phase.

Effect of Crystallographic Texture on Anisotropy of Yield Strength in X100 Pipeline Steel

Journal of Iron and Steel Research International, 2013
Abstract The anisotropy of microstructures and mechanical properties in commercial American Petroleum Institute (API) X100 pipeline steel was systematically investigated by experimental measurements. The experimental results show that anisotropy of yield strength could be observed considerably, which should be attributed to the crystallographic ...

Effects of Finish Cooling Temperature on Microstructure and Properties of X100 Pipeline Steels

Materials Science Forum, 2016
The effect of finish cooling temperature on microstructure and mechanical properties of X100 pipeline steels were investigated through SEM, TEM and mechanical tests. The results showed that the effect of finish cooling temperature on tensile strength of studied steels were slight in the temperature range of 180°C~500°C.
