Curved-Wide Plate Testing of X100 Girth Welds

Volume 4: Production Pipelines and Flowlines; Project Management; Facilities Integrity Management; Operations and Maintenance; Pipelining in Northern and Offshore Environments; Strain-Based Design; Standards and Regulations, 2014
Curved-wide plate (CWP) tests are frequently used for assessing the quality of pipeline girth welds. Despite a large number of CWP tests having been conducted at great expense over many decades, an industry consensus standard remains unavailable. Considerable effort at several research institutions is focused on the standardization of test protocols ...

Design, Application and Installation of an X100 Pipeline

Volume 3: Materials Technology; Ocean Engineering; Polar and Arctic Sciences and Technology; Workshops, 2003
Traditional pipeline technology will be severely challenged as design-operating pressures continue to rise and gas field developments occur in more remote locations including the arctic. Cost-effective solutions to these issues can be found through innovative designs using new technology and its implementation. Some of these designs have considered the

Effect of Vanadium Addition on Api X100 Linepipe Steel

2015
This 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 ...

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.

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.

Reheating Treatment of X100 Bend Pipe Steel

Volume 6: Materials and Fabrication, Parts A and B, 2012
Oil 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.

X100 Linepipe With Excellent HAZ Toughness and Deformability

Volume 3: Materials Technology; Ocean Engineering; Polar and Arctic Sciences and Technology; Workshops, 2003
Good low-temperature toughness of the base material (BM) and weld heat-affected zone (HAZ), and good deformability of the pipe body together with good field weldability are required for X100 linepipe to ensure the safety of pipelines and to facilitate field welding. It is, however, very difficult to attain these properties simultaneously because of the
