Welding with High Power Fiber Laser API5L-X100 Pipeline Steel

Materials Science Forum, 2010
The increasing length of oil and gas transportation pipelines, associated with their construction and operating costs, has lead to the development of new steel grades with higher performance. The API 5L- X100 is a new high strength steel for pipeline applications which enables the use of thinner walled pipes, lighter to transport and easier to handle ...

Evaluation of environment-assisted cracking susceptibility of a grade X100 pipeline steel

Corrosion Science, 2012
Abstract Susceptibility of as-received grade X100 steel was compared to that of simulated and seam-weld heat-affected zone microstructures by slow strain rate testing in a sodium hydrogen carbonate–sodium carbonate solution at 75 °C over a potential range of −500 to −1100 mV vs. standard calomel electrode (sce).

Correlation of initiation of corrosion pits and metallurgical features of X100 pipeline steel

Canadian Metallurgical Quarterly, 2013
AbstractIn this work, corrosion pits initiated on X100 pipeline steel and their correlation with the metallurgical features of the steel were characterised by scanning electron microscopy and energy dispersive X-ray spectroscopy. It was found that pits are always associated with various inclusions.

CTOA Results for X65 and X100 Pipeline Steels: Influence of Displacement Rate

2008 7th International Pipeline Conference, Volume 3, 2008
The toughness and plasticity of steel generally decreases with increasing testing rate. The crack tip opening angle (CTOA) was measured on two types of commercial pipeline steels API-X65 and API-X100, at a range of displacement rates to characterize rate effects. The testing was conducted at quasi-static and dynamic rates.

Physical Simulation on Microstructure and Properties for Weld HAZ of X100 Pipeline Steel

Materials Science Forum, 2013
In this paper, the simulation heat affected zone (HAZ) continuous cooling transformation (SH-CCT) diagram of X100 pipeline steel was drew by using Gleeble 3500-HS thermal/mechanics simulation test machine, and the microstructure and properties of the HAZ of single-pass/double-pass welding were simulated and studied.

A New Corrosion Mechanism for X100 Pipeline Steel Under Oil-Covered Chloride Droplets

Corrosion, 2018
A 1.7 mM NaCl droplet on X100 pipeline steel covered by paraffin oil is used to simulate the corrosive environment encountered in heavy oil or bitumen pipelines. The development of corrosion under the droplet was monitored and explored in two stages. In the initial stage (1 h), the distribution of corrosion pits was heterogeneous with one area under ...
