US Army denies DAPL easement, AFPM responds to decision

HOUSTON (Reuters) -- The US Army's denial of an easement for the Dakota Access Pipeline, after permitting and legal obligations were followed, sets an uncertain precedent for new projects despite President-elect Donald Trump's promise to support energy infrastructure.

Causes and mitigation of thermal bowing in process piping design

Darji, P., Dholakia, M., Chaube, N., L&T-Chiyoda Ltd.

The authors encountered pipe thermal bowing problems in recently executed projects. These practical problems are discussed in three case studies, after a brief description of the thermal bowing concept and common reasons for the occurrence of this phenomenon.
