Failure Assessment for the High‐Strength Pipelines with Constant‐Depth Circumferential Surface Cracks [PDF]
Advances in Materials Science and Engineering, Volume 2018, Issue 1, 2018., 2018 In the oil and gas transportation system over long distance, application of high‐strength pipeline steels can efficiently reduce construction and operation cost by increasing operational pressure and reducing the pipe wall thickness. Failure assessment is an important issue in the design, construction, and maintenance of the pipelines.

Effect of Austenitic State on the Multi-phase Control in X90 Pipeline Steel with High Nb Content
Materials Today: Proceedings, 2015 Abstract This work focuses on the effects of different austenization temperatures on the continuous cooling transformation kinetics and the ultimate microstructures characteristics of 620 MPa grade (X90) pipeline steel. The results indicated that the austenitic state has significant influence on the diffusive transformation with the cooling rate of 1
