This project focused on the gathering, dissemination, and identification of critical variables affectng line pipe steels in hydrogen service. Published studies from US government labs (e.g., NIST, Sandia) and global publications were reviewed and…
Based on the investigation of the recent pipe failures, it was clear that HAZ softening was one of the contributing factors. To understand the factors that influence the susceptibility to HAZ softening, a simple weld bead-on-plate testing procedure…
This report summarizes the effort to evaluate the sour fracture toughness properties of two thermo-mechanically controlled processed (TMCP) pipes and a plate material in sour environments with different H2S partial pressures. The primary objective of…
Some instances of substandard high yield (42-80 ksi) fittings and flanges have been reported over the past few years in Canada and the USA. In response, PRCI launched project MAT-7-1 to investigate some of the potential metallurgical causes of this…
This report is a literature review of several non-metallic material systems often used as alter-natives to steel pipelines. The pipeline systems reviewed are high density polyethylene (HDPE), fiberglass rein-forced plastic (FRP), flexible composite…
PRCI required guidelines for pipeline valve stem seals in CO2 rich applications such as for enhanced oil recovery (EOR) and carbon capture and storage (CCS). In particular, guidance was needed to ascertain when standard O-rings may be used, when a…
The general objective of the PRC Line Pipe Research program from 1953 to 1962 has been to obtain the highest quality pipe possible within economic limits. The results of research conducted during this nine year period was presented to at an industry…
Pipeline Research Council International, Inc. (PRCI) required guidelines for pipeline valve stem seals in CO2 rich applications such as for enhanced oil recovery (EOR) and carbon capture and storage (CCS). In particular, guidance was needed to…
