Traditionally in pipeline steels and welds, ultrasonic testing (UT) has been used for crack and/or flaw detection. The work presented in this Thesis explores the use of this technique to characterize the microstructure of pipe steels. Ultrasonic velocity calculations, for shear and longitudinal...

Casing pipes used in sour service are prone to two forms of failure: hydrogen induced cracking (HIC) and sulfide stress cracking (SSC). The objective of this thesis is to investigate the resistance of L80 ERW and Seamless steel pipe, with five different chemical compositions, to both HIC and SSC....

Modeling of the Effect of Run-out Table Cooling on the Microstructure of a Thick Walled X70 Skelp
DownloadSpring 2018
This thesis presents work performed to model and measure the effect of run-out table cooling on a thick walled X70 steel. During run-out table cooling, the steel undergoes several phase transformations that will affect its microstructure, and thus, its mechanical properties. To predict the steel...
