Welspun, the India-based corporation, made a key decision to build a line pipe mill in the state of Arkansas during the midst of the Great Recession. It was a gamble, but one predicated on the belief that the American shale industry was about to boom and they would be centrally located.
Part 2: Low Temperature Ductility And Ductile Crack Arrest Properties Of High Strength Low Alloy Steel
We stated in Part 1 of this two-part series that one of the most critical decisions in pipeline design is the quality of steel. We also discussed the importance of steel quality in terms of the quality of pipe. Pipe, after all, is a dimensional aspect of material and, for this discussion, the material is steel. The discussion on steel making especially focused on low-temperature ductility and steel’s ability to resist initiation and arrest of ductile cracks.
The emergence of micro-alloyed, high strength steel in pipeline applications has opened opportunities for more specialized studies of low-temperature ductility loss and the possibility of crack development. We will discuss the subject further in still more stringent design conditions that challenge engineers and operators.
