Phase Behavior of Tyloxapol/Triton X100/Water Mixtures
Journal of Pharmaceutical Sciences, 1995The influence of admixture of Triton X100 to the polymer tyloxapol and the phase behavior of the mixtures in contact with water was investigated by viscometry, polarization microscopy, and X-ray scattering. The viscosity of tyloxapol/Triton X100 mixtures is lower than that of pure tyloxapol.

Local Buckling Behavior of X100 Linepipes
Volume 3: Materials Technology; Ocean Engineering; Polar and Arctic Sciences and Technology; Workshops, 2003Local buckling behavior of API 5L X100 grade linepipes subjected to axial compression and/or bending moment is discussed in this paper based on results obtained by finite element analyses. Yield-to-tensile strength (Y/T) ratio and design factor were taken into account in the finite element analyses in order to discuss their effects on the local ...

Girth Welding of X100 Pipeline Steels
4th International Pipeline Conference, Parts A and B, 2002Girth 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

Construction and Installation of X100 Pipelines
2004 International Pipeline Conference, Volumes 1, 2, and 3, 2004The developments of gas fields are increasingly occurring in more remote locations and further from the prime gas demands. Pipeline activity continues to focus on arctic regions of both Canada and the United States. Cost effective solutions to these challenges can be found through innovative technology and the use of higher pressure and higher strength

Welding X100 steels for gas pipelines
Welding International, 2004Abstract 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 ...

X100 (Grade 690) Helical-Welded Linepipe
2008 7th International Pipeline Conference, Volume 3, 2008During the past ten years, linepipe development activities around the world have been focused on high strength steels for Arctic gas transmission. The incentive for this work has been the potential for greater transportation efficiency and lower construction costs associated with the use of higher strength steels.

Photoexcited fullerene species in Triton-X100 micelles
Journal of the Chemical Society, Faraday Transactions, 1997Photoexcited states of fullerene C60 have been studied using laser flash photolysis and near-IR spectroscopy. In order to stabilise these species the C60 molecules were incorporated into aqueous micelles of reduced Triton-X100 (TX100-R). Mechanistic studies show that C60− can be formed in the presence of an electron donor, such as sodium ascorbate, via

Science and Technology of Welding and Joining, 2000
Research has been carried out to identify weld metal compositions and microstructures capable of meeting high strength and toughness requirements for X100 seam welded linepipe. Single pass, multiwire submerged arc welds were made in experimental, high strength low alloy steel plates using consumables to give a wide range of weld metal alloying.

Ductile failure of X100 pipeline steel – Experiments and fractography
Materials & Design, 2013Abstract 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 ...
