Girth Welding of X100 Pipeline Steels

4th International Pipeline Conference, Parts A and B, 2002
Girth welding trials involving pipes of minimum proof strength 690 MPa (X100) from several linepipe manufacturers have been conducted. Welding consumable selections for the trials were based on background data generated at Cranfield University coupled with potential weld metal mechanical property requirements thought necessary for the implementation of

Welding X100 steels for gas pipelines

Welding International, 2004
Abstract The increasing demand for high strength steel (to date not included in the standards for pipe material specifications) for dedicated long distance pipelines for natural gas transportation at high pressure (≥ 10 Mpa) has prompted studies of the overall integrity of both the pipe and the girth welds used, fundamental parts of the structural ...

Ductile failure of X100 pipeline steel – Experiments and fractography

Materials & Design, 2013
Abstract Ductile failure of X100 pipeline steel is studied. In order to study the effect of anisotropy, triaxiality factor and Lode angle on the failure, a series of specimens with different geometries are tested. Measurements of deformation in three dimensions are done to check the variation of elongation and lateral deformations during loading ...

CTOA Measurements of Welds in X100 Pipeline Steel

2008 7th International Pipeline Conference, Volume 3, 2008
A suite of tests characterizing X100 pipeline steels was initiated at the National Institute of Standards and Technology (NIST) in Boulder. Part of the test matrix included testing the toughness of the base metal, welds, and heat-affected zones (HAZ) by use of modified double cantilever beam specimens for crack tip opening angle (CTOA) testing.

Characterization of fiber laser welds in X100 pipeline steel

Materials & Design, 2009
Recent 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 ...

Microstructure and Properties of X100 High Strength Pipeline Steel

Materials Science Forum, 2015
In order to study the effect of welding process on the microstructure and properties of weld joint of X100 pipeline steel, GMAW was used to prepare the weld joint with low-carbon high manganese-molybdenum-nickel flux cored welding wire. SEM and XRD were used to analyze the microstructure and phase morphology of HAZ and weld metal.

Development of High Steel Grade Seamless X100 Weldable

Volume 3: Pipeline and Riser Technology; Ocean Space Utilization, 2008
The 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.

A Weldability Study of Steel of Strength Class X100

Metallurgist, 2014
The effect of welded joint heat-affected zone (HAZ) cooling rate on structure, mechanical properties and brittle failure resistance of pipe steels of strength class X100 is studied by simulating welding thermal cycles in a Gleeble-3180 test unit.
