The birth and evolution of high temperature processed (HTP) linepipe steels

Significant long distance infrastructure projects, to expand the world’s oil and gas distribution network, have been steadily emerging across the continents.

Kirkwood, Phil
The pipe needed for such initiatives is now often required to be of the higher strength API 5L X70 or X80 grades and also tends to be of much larger diameter with increased wall thickness. These combined changes reflect the need to quickly transport increasing volumes of hydrocarbons at higher pressures.

Strengthening Mechanisms and Their Relative Contributions to the Yield Strength of Microalloyed Steels
The Charles Hatchett Award is important to identify new applications and markets for Niobium. Introduced over 40 years ago, The Charles Hatchett Award is a prestigious recognition that aims to identify new applications and markets for Niobium. The award is sponsored by CBMM | Niobium and recognizes the best published research on the science and technology of Niobium. The annual award brings together technical experts worldwide, and a panel of international experts selects the winning paper. The 2013 Charles Hatchett Award winners’ presentation aims to understand the strengthening mechanism of micro alloyed steels by determining strengthening contributions due to the effects of the grain size and the influence of precipitation.
