Research on Hot Deformation Behavior of the X100 Pipeline Steel
Applied Mechanics and Materials, 2014The hot deformation of X100 pipeline steel was studied in the temperature range of 800~1200 °C and strain rate of 0.1~40s-1 on Gleeble-1500 thermal mechanical simulating tester. The effect of deformation conditions on the flow stress was analyzed. The constitutive equation of hyperbolic sine including Z parameter was used to describe the relationship ...

The Underoil Droplet Corrosion Behavior of X100 Pipeline Steel
ECS Meeting Abstracts, 2018Canadian natural bitumen production will reach a peak of 112 million barrels per day in 2078 [1]. Pipelines are primarily used to transport this bitumen. Bitumen must be diluted in order to be pumped through a pipeline effectively because it is otherwise too viscous to flow [2].

Effect of Vanadium Addition on Api X100 Linepipe Steel
2015This study is focused on the effect of vanadium addition to an API X100 steel. Laboratory heats were melted and control rolled based on a coil plate production process. Compared to non vanadium steel, it was found that 0.06% vanadium added steel had 8 to 14% higher yield and tensile strengths in all directions, while the toughness and ductility were ...

Development of High Steel Grade Seamless X100 Weldable
Volume 3: Pipeline and Riser Technology; Ocean Space Utilization, 2008The technological evolution in the offshore sector points out a trend towards an increasing use of high strength steels (grade 80ksi and higher), for both pipelines and risers. Pipeline specifications for deepwater offshore fields demand developments in design criteria (i.e. limit state design), welding, installation, and laying technologies.

Characterization of fiber laser welds in X100 pipeline steel
Materials & Design, 2009Recent developments in steel grades for pipeline applications have lead to new high strength grades, such as API5L-X100. Higher strength enables the use of thinner walled pipe, with greater operating pressures and reduced overall costs. The base material presents good toughness values; however there are still limitations regarding the weldability of ...

Development of X100 Linepipe Steel With High Deformation Capacity
2008 7th International Pipeline Conference, Volume 3, 2008Recent linepipe steel is required to have enough deformation capacity through longitudinal direction at severe environments such as permafrost or seismic region, even though after anti-corrosion coating treatment in pipe. Under this background, the development of X100 linepipe steels with high strain aging resistance was tried.

Reheating Treatment of X100 Bend Pipe Steel
Volume 6: Materials and Fabrication, Parts A and B, 2012Oil gas is the most clean fuel. Till 2020, the requirement of oil gas will increase 104%, but consumers are mainly live in developed cities, and oil and gas resources are located in ice field, hungriness, ocean and polar place. That is, the undeveloped resources are remote from the cities.

Development of X90 and X100 Steel Grades for Seamless Linepipe Products
Volume 3: Materials and Joining; Risk and Reliability, 2014The general trend in oil and gas industry gives a clear direction towards the need for high strength grades up to X100. The exploration in extreme regions and under severe conditions, e.g. in ultra deep water regions also considering High Temperature/High Pressure Fields or arctic areas, becomes more and more important with respect to the still growing
