Arresting propagating shear in pipelines (Part 2. See no. 1, 2015 for part 1)

Autor: B. N. Leis

Publikováno v: Steel in Translation. 45:161-174

The consequences of what has been termed running ductile fracture require that pipelines be designed to arrest propagation, and so avoid major incidents due to this type of failure. Approaches to characterize pipeline response and their resistance to

Hydrocarbon pipelines transporting compressible products like methane or high-vapor-pressure (HVP) liquids under supercritical conditions can be susceptible to long-propagating failures. As the unplanned release of such hydrocarbons can lead to signi

Publikováno v: Volume 2: Pipeline Integrity Management.

The types of defects that have caused in-service failures and hydrostatic test failures of natural gas and hazardous liquid pipelines comprised of electric resistance welded (ERW) or flash-welded seams were revealed by a study of 569 seam failure inc

Experimental Determination of Constraint Dependent J-R Curves for X80 Pipeline Steel Using Normalization Method

Autor: B. N. Leis, G. Shen, Xi. K. Zhu, W. R. Tyson

Publikováno v: Materials, Nondestructive Evaluation, and Pressure Vessels and Piping.

The normalization method is adopted for standard specimens and extended for nonstandard specimens in this paper to develop J-R curves for X80 pipeline steel directly from load versus load-line displacement records without the need of crack length mea

Hydrotest Protocol for Applications Involving Lower-Toughness Steels

Autor: R. D. Galliher, B. N. Leis, R. Sahney, R. L. Sutherby

Publikováno v: 2004 International Pipeline Conference, Volumes 1, 2, and 3.

Hydrotesting has been used by the transmission pipeline industry for decades, and remains the only effective means to control stress-corrosion cracking until in-line inspection is proven. This paper addresses the conditions for effective proof-pressu
